  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.
