  1. God plan Mest referanse til å få pulverlakken til å dekke i høy luftfuktighet, tror vi er trygge der
  2. De ser i alle fall fine ut, håper de går godt. Pulverlakk setter seg vel konge også, i alle fall om du er på Østlandet, aka Nye Sahara
  3. OK, last update, promise. Almost certain.. (3 subjects in this post) I was elated to have 25 .357/45 cartridges based on the 8x33 cases “plunk”, but unfortunately, the string was not consistent. I still had the occasional cartridge that would not plunk/feed. Diagnosis: Flat based bullets being showed down the throat of an insufficiently supported case neck sometimes would lead to a kink/bulge in the neck, causing problems. New fix: A Lee Factory Neck Crimp die. This is the same type of die we know from rifles – 4 fingers come in to press the neck straight & tight. Wonderful. Surprisingly, Lee has overlooked the .357/45 GWM, but they have made one for .357 SIG. The .357 SIG is based on the .40 S&W case, about 10mm dia at the base, where the .357/45 is about 11mm. The SIG is also a bit shorter than the GWM. The Factory Crimp Die (FCD) has a sleeve that impacts the shell holder, the sleeve then pushes the four crimp fingers together. So. I drilled out the sleeve, and added a small extension to the sleeve, to compensate for the difference in case length. And now, by Jove, I can consistently turn out 100’s of cartridges that actually chamber and go boom every time. Happy OK, that was the plunking & FCD. I still had problems getting the cartridges to feed well, getting up the ramp without stopping. Fix: Several deep breaths, get out some non-marring pliers, and carefully bend in the feed lips at the rear end. The “next” cartridge now pops up, and is kept in place by the indent in the feed lips, creating a good trajectory towards the chamber. I can even load 110gr HP bullets without hiccups. Those 110grs HP (Sierra something hollow cavity) brings me to the final item. I was wondering if I could get them out at 2000 fps (610 m/s). The answer is no. I can (safely) get them out at 1880 fps (573 m/s), which is an interesting experience (type: the fillings in your molars are shaking loose). The loads at 1940 fps (591 m/s) showed an impressive range of indications that I’ve never seen in a handgun before: Primers backing out, cratered primers, bent rims from the extractor etc. That’s not the actual third subject – the observation is that although the slightly smaller rim diameter of the 8x33 is a minor issue, of course the rest of the case head is similarly slightly smaller. So if you go tickling the dragons tail by for example trying to push a 110gr at 2000 fps, the case (quite a bit ahead of where we go looking for the pressure ring), expands quite severely. This is of course an indication that you’re in the red on this load, and secondarily, the cases needs to be discarded. Calling it a night here, I may actually have beat this project
  4. Kan jeg få noen pekere i riktig retning? Halvauto rifle, gass, .300 BLK. Trenger en treningsladning som samler greit. Klarer ofte å holde 10'ern på DFS skiva med Lapua 123gr og 190gr Sierra MK. Samme, eller ikke så mye verre, hadde vært bra Supersonic, kanskje helst, typ 150-160gr. Pulverlakk er jeg god på (fra pistol) Så: hvilken kule, typ 150-160gr, aaaaller helst som ikke trenger GC, med PC, til typ 1700-1900 f/s, til ei knøttlita hylse, trangt kammer, kort throath, hvor de eneste vettuge kruttene jeg har funnet er N110 og N120. Kjappere krutt lager ikke gass nok, de langsommere er det ikke plass til. Åja. Må passe til OAL som går i magasinet. Og ikke være for tjukk over nesa, da kamrer de ikke. Ellers ingen begrensninger Tips?
  5. Tror du/dere skal sjekke litt. Mulig en norsk børsemaker må ta delene inn, generere et unikt nummer, melde til onkel og gravere inn nummeret. Det er i alle fall sånn Brownells gjør det - tar inn unummererte deler og tar ut et unikt N-... nummer
  6. A few more comments: 1: The case necks are rather rough after sizing & fireforming. Neck chamfering is a good idea. 2: The Kurz cases give a little (~50 ft/s) lower velocity than the .308-cases, indicating that the case volume is a little larger. I've upped the load with 0.6 grains I've just loaded 30 fireformed / fireformed + 1-time fired cases, and they all plunk. I've loaded them with varying OAL from 39.9 - 40.6mm, to see if a particular OAL is better for loading/chambering from the magazine
  7. Jeg tror hovedpoenget er at store magasiner har man litt dårlig erfaring med i enkelte, ganske spesifikke, tilfeller. De som hadde langmag før 1.10.2022 tok sikkert bilde av dem på toppen av Aftenposten den dagen, så er de i boks. De som skyter nok i skyteprogrammer som krever lange magasin og som ikke var i posisjon 1.10.22, er også i boks, etter litt papirarbeid.
  8. OK, I realize that this is mostly my own personal scratchpad now. But I now will draw the attention of the audience (mostly me) to the fact that I have tonight loaded 25 .357/45 GWM cartridges that have a 100% "plunk" rate when dropped into the barrel/chamber of the 357/45 GWM. They also headspace correctly, and here was no "oh, that was odd". Only took two years. The recipe is : (thanks to @de50ae for the 8x33 idea) : 1) Buy the CH4D dies. Throw away a bit of the set, but keep the sizing & seat/crimp die. 2) Grid off a bit off the bottom of the size die. How much must be determined later 3) Get hold of a .357(8) rifle type expander die. I use a .358 Win die, with most of the body sawed off, so I can use the expander. I have ground the expander button down a bit. 4) Get some 8x33 Kurtz shells. This removes soo much hassle compared to .308 Win. .44 Automag might still work, though. 5) Expand the 8x33 shells on the die mentioned in 3), add primer, powder, shells. I ended up with a light bullet and a reasonably full load. 6) Fire. Go looking for the shells. 7) Here we're back to the "you need to grind off the bottom of the sizing die a bit". Grind until a fire-formed 8x33 plunks in the chamber, and then a bit more. 8} I then size the cases until they plunk, then a bit more. (Very important step :)) 9) Expand the case necks, with the .357 expander ball, so you can seat the bullets 10) prime, powder, seat. My 25 .357/45 GWM cartridges now "plunk", and headspace right. I've found that seating the bullets long helps with feeding. I also apply a hefty bit of crimp. The Grizzly is not kind on the cartridges, and because the .357/45 GWM tapers a lot more than the .45 Win Mag it actually was designed for, the .357's get a nose job every time they're fed. So heavy crimp I feel this heavy crimp is a part of the "that's odd - some chamber, some don't". But is seems like the extra pushback from the sizer alleviates the possible bulges caused by the .357 flatbase brutally showed down + the rather heavy crimp. The "then a bit more" seems to be the clue here. When the fireformed and sized cases "plunk" in the chamber, there is still a bit of room for trouble. And that has been nagging me. But adding a wee bit of extra case neck push back still lets them headspace right, after a .357 has been showed down the throat. This is of course because the CH4D dies are actually not .357/45 GWM sized. But one works with what one has. I will now epoxy down the position of the size, expander and seat dies, after I've made the journey from 8x33 to .357/45 GWM from fresh cases one last time. Then I'll quit posting here
  9. Ja, tillatelsen gjelder for "uendelig " antall, til det ene spesielle våpenet. Står på våpenkortet til evig tid
  10. Ang spørsmålet om man får eget våpenkort på magasin: nei, det skrives "kan erverve høykap mag" på våpenkortet til rifla
  11. Er nok ikke relevant i dette tilfellet, men jeg hørte en kreativ løsning på Svenskehandel for de som bor i nærheten av grensa: Bestill pakke til postkontor til eget navn og en fiktiv adresse i f.eks. Strømstad. Oppgi egen tlf og epost. Når pakken kommer til postkontoret får du melding og reiser og henter den.
  12. Hvis han skal beholde huset i Norge og ha "bustad" det, kan han oppbevare våpnene der, selv om han ikke fysisk er der. Long shot
  13. Beklager å rane denne gamle tråden, men kunne noen hjulpet meg med Våpenjournalen nr 4/1985? Det nummeret skal ha en omtale av L.A.R Grizzly i .45 win mag jeg gjerne skulle sett.. Scan/foto/salg?
  14. Og enda mer kort innpå - messingformer med 4 - 6 hull er møkk tunge. Og støtter at MP molds er bra greier.
  15. Gongrats on the win I bowed out of both relevant championships this year due to Covid. Do you have classes for "357 mag" type guns & "44 mag" type? Here they're called Mag1 (Ø<=10mm, factor > 190) and Mag2, (Ø>10mm, power factor > 275) Regarding feeding & length: With FN bullets I frequently get cartridge 5 or 6 caught on the feed ramp, with a sad ending for that cartridge. My cartridges (from number 2-3, are pointing downwards significantly. So - RN bullets, real jacketed so they don't deform, and now with an extra long OAL. I fed atleast one 7 shot mag of these without fail. With FP bullets & 40,3 OAL, 1-2 FTF per magazine. I have new magsprings, but the magazines & followers have seen some use.
  16. Interesting result with the .45 WM cases Glad I never loaded those. But your 7,92x33 idea still works well :) I've fireformed 40 cases, and have been tinkering a bit. First of all: the strange phenomenon that one loads 1-2 cartridges that "plunk" in the chamber, then at least some of the others don't - I get that too. All cases are fire-formed, then neck sized (because of my dies), expanded, bullet seated and a crimp applied. The dies are locked with set-screws, and still - differences. I've noticed that I get it more frequently with Frontier copper-coated .358 dia bullets than with .357 FMJs with a proper copper jacket. But still - it's sort of "organic" - happens with some, not all. I'm suspecting minor case thickness variations + an extremely tight neck. I use cheap 125 gr Frontiers for fire-forming. They can be loaded 2 per magazine, and feed OK. I had some problems getting this to work with mild N340 loads, so now I tried 18gr of N110 (basically because I was too lazy to change powders & powder measure settings. That works quite well At least they eject quite nicely, with a quite impressive fireball & "wooomph" I tried the 125s + some 158 Frontiers today - they work OK even if the chambering is not "drop free". But I keep getting failures to feed on round 5-6. Short rounds, steep angle, rough feed ramp. So, I tried loading the 170gr FMJ's way out - as far as I could get them, while "plunking" in the chamber and fitting in the magazine. That worked way better - fired two full magazines without failures to feed. I'm at 18gr N110 now while playing with the dies, bullets & seat depth. I've been up at 20gr N110 with a 158gr lead TC @524 m/s, and at 479 m/s with a 15gr charge of N105, there's headroom there, too. A 105gr Lee SWC leaves at 622 m/s in front of 19,5gr N105 My selected load will probably be the Sierra 170gr RNs with 18,5gr N110 at 480m/s. There is more headroom, but if I go there, the cases tend to bang against the top of the slide and get dented. So: Long cartridges, RN, jacketed bullets for feeding. Some variation in feeding reliability between magazines. (I have new springs all around) The variation in "plunkiness" still unsolved. The CH4D dies work, sort of, if used for neck sizing.
  17. I've been away too long. I just learned, from my own posts, how to get from 7,92x33 to chamberable .357/45 for fireforming. Good thing we write stuff down
  18. OK, I'm back. @de50ae - seems totally like your dies are SO much better than the CH4D dies - that's great (at least for you :)) I've been down with Covid for a while, but I've started experimenting again. It seems like I can use the CH4D dies as a "neck crimp" die. Just loaded 10 once-fired Kurtz shells with just enough forming to have them fit, without messing up the shoulder. These "plunk" in the chamber, bullet hold good, will try on Saturday. Now I probably need to work out how to get cases to chamber for fire-forming, then neck-size for full loads. Anyway - looking better
  19. Hi, this isn't over. Today's test shooting was a bad show I'll get back to that, let me answer your questions first. This problem of buckled cases did not occur with the .308 cases, since there I had problems with getting ENOUGH hold on the bullets. The Kurtz is grabbing on for dear life, which is a good thing. When I seat a flat base bullet, at a point in the seater die when the case neck is not fully supported, the bullets tend to kink. I stopped half way on one of them, and it looked like a tongue in cheek thing. I pressed home and crimped, but it won't chamber. So - the rifle style expander button is a must. Considering adding a bit of trumpet, too Attached is a photo of: A 308 win cartridge for reference. A Kurtz that won't chamber A Kurtz that "plonks" into the chamber A Kurtz that had a bad time at the feed ramp A Kurtz that the extractor caught A fired Kurtz. Edit: I just spotted something in my own picture. The Fired & formed cases are way different than the fired cases. Look at the shoulder, the shoulder angle & the length of the neck. F**ck. I knew those CH4D dies were iffy. F**k Then about today.. I had loaded 40 cartridges with a moderate load, 8,6 gr N340, for a factor of about 200-210 with a 170gr bullet, to be easy on my hands & shoulders. This was too little oomph against the 27lbs recoil spring, and several cases were caught on the extractor and followed the slide back to smack into the chamber wall. It seemed like the extractor was holding a death grip on the case, and the ejection didn't work. I switched to a weaker spring, this let the cases eject fine, but this spring didn't have enough power to force the cartidges up the feed ramp. The taper of the 357/45 is probably larger than the .45 win mag, and they tend to go nose first into the frame ramp and get stuck unless there's a huge force driving them. So: Feed ramp not optimal Need lots of bang to have the extractor lose its death grip on the case and let the ejector do its work. Have no idea why a THINNER rim should produce that death grip. Isn't smaller diameter, too? I don't get it. The Kurtz is actually closer to the .45 Win Mag (that I assume the GWM is built from) than the .308 is. I'll need a break from this project for a while, while I ponder..
  20. A quick update - this wasn't as easy as I hoped. The process for a fireformed case is: Size (calibrate) and decap, expand neck with rifle type expander, then powder, seating and crimp. I tried seating without expanding or expand with a pistol-type expander. That didn't work, the case neck buckled. Even though the crimp straightens the neck, the remaining bulges still stop the round from chambering well. I mucked about for hours yesterday to find the best expansion and the correct level of crimp. Will test-shoot today. Powder charge for fireforming - I have no opinion. What i've read that you should use a mild load, that's all. The reason for the single loading is that the cases taper too much, so the cartridges hit the loading ramp too low when I tried to feed them from the magazine. Sizing/calibration after expansion does not fix this, as the case is too slender, not too thick. They pop out to their intended minimal taper in the fireform.
  21. Possibly the last update for a while, from here on in, I think it might be mostly shooting this thing, not fighting it. I expanded 90 cases of 7,92x33 Kurtz on a chopped down .358 Win die. Primed with Federal Large Rifle, and Magtech Large Pistol when i ran out of the Federal. Added a .32 S&W Long caseful of N32C, seated a Frontier 158gr FP, crimped. Did not size in a .357/45 sizer, the cases headspace perfectly even though the shoulder is the wrong angle and in the wrong place. Went to fireform. Ended up swapping the spring for a .45 ACP spring, and then single loading a cartridge at a time. The reason for the single loading is that the 7,92x33 Kurtz is way more tapered than a .357/45 GWM, so the cases tend to dip into the feedramp before having been fireformed. So trying to load from a magazine gets tired, fast. The .45 ACP spring is still strong enough to hold back that dash of N32C, and believe me, when yanking back the slide to eject the case, you want the ~14 lbs .45 ACP spring to fight back, not the 27 lbs .357/45 spring. I'm now in the posession of 99 fireformed, washed .357/45 GWM Kurtz cases - next step is some reloading, then actual shooting
  22. I fireformed 10 today, and can report a 90% success. Actually close to 99,9%, this was fun The cases are from "GRAF", and judging from the look of the package, have been in stock a few years. I simply expanded the cases with the .358 dies, and seated a bullet. The bullet hold was good, and although the case was a loose fit in the chamber, the headspace was "incidentally" correct, although the start of the shoulder and shoulder angle are different. So making ammo for fireforming is just "expand, prime, add powder, seat bullet, crimp, bang". The expander button was originally .358, but I believe i have ground it down a bit. After firing they looked great, and I've dummyloaded a fired case. Size in the CH4d (without an expander button), seat bullet & add crimp - worked well. I've noticed that the bullet starts really tight, and becomes easier to push as we go down the case, but since we end in a nice crimp, I think we're good. The missing % was from the load of N32C. I used a .38 special case as measure, and loaded a full measure into each case. Unfortunately, this was enough to partially open the action, but not enough to eject. So the first shell was smashed into the chamber wall as the slide returned and was smashed. Possible remedies,while fireforming: 1) Increase load to make action cycle 2) Reduce load to ensure it doesn't open at all 3) replace the 27 lbs spring for .45 Mag / .357/45 with the one from .45 ACP to make the action cycle 4) manually slow down the slide for each shot with your thumb from the other hand. I chose 4) to get 9 nicely formed cases. My thumb is not sure if that was the best option, so I'll probably go for 1) in the future In all - we have a winner. Thank you so much for sharing your idea and building on our common knowledge The cases from 7,92x33 behave at least as well as the formed .308's. We have to fireform first time, but that is SO much easier than the forming, sawing, trimming & reaming. Thanks
  23. Yup, 'cept it drives a 170gr at 1670 f/s, and a 105 at 2040, from a 6,5" barrel Should be interesting from a 18-22" barrel
  24. Behold Possibly the worlds first ever 357/45 Kurtz. Sincere thanks to @de50ae for the brilliance to think of the idea Made with a combination of RCBS .358 Win & CH4D dies. 170 grs Sierra FMJ, a full .38 Special case of N32C (No idea of the weight, but way below any threshold). Should fireform the cases nicely, but won't eject, thus saving me some case chasing Looking forward to the reload
