Mightymoo Posted June 21, 2013 Share Posted June 21, 2013 Har kjøpt 1000 stk Berrys 38 Special 158gr RN (kobberbelagte blykuler). Skal lade treningsammo for skyting ut til 50 yards. Fra Berrys side:Plated bullets occupy a position between cast bullets and jacketed bullets. They are soft lead, but have a hard outer shell on them. When loading plated bullets we have found best results using low- to mid-range jacketed data in the load manual. You must use data for a bullet that has the same weight and profile as the one you are loading. Do not exceed mid-range loads. Do not use magnum loads. Har sjekket ladedata på Lapua: http://www.lapua.com/en/products/reloading/vihtavuori-reloading-data/relodata/6/28 Vil følgende oppsett fungere fint for en nybegynner? - Federal SP tennhetter - Vihtavuori N350 - 5,5gr ladning - Berrys 158gr copperplated roundnose Hvilken C.O.L anbefales, da jeg ikke finner rundnesede kuler i tabellen til Lapua? Det er her anbefalt en C.O.L på 38,1mm: http://www.brianenos.com/forums/index.php?showtopic=30809 Be careful comparing other CPRN bullet recipes. The Berrys 158 gr CPRN is much longer than most (0.690" vs ~ 0.600") , so CTG OALs/resulting internal V & P/velocities will be significantly effected. Høres det greit ut? Takker for alle innspill/kommentarer Quote Link to comment Share on other sites More sharing options...
Erlend Meyer Posted June 21, 2013 Share Posted June 21, 2013 Helt feil krutt, du vil nok være tjent med N310 - 340 avhengig av nivå du er ute etter. Quote Link to comment Share on other sites More sharing options...
ivara Posted June 22, 2013 Share Posted June 22, 2013 er jo 158 rainier FP i tabellen, som også er belagte kuler. Er de noenlunde like Berry mtp ladedata? Quote Link to comment Share on other sites More sharing options...
mauser69 Posted June 22, 2013 Share Posted June 22, 2013 3grs N310 eller 3,5-3,8 grs N320 vil fungere fint til den kula M Quote Link to comment Share on other sites More sharing options...
ivara Posted June 22, 2013 Share Posted June 22, 2013 er jo 158 rainier FP i tabellen, som også er belagte kuler. Er de noenlunde like Berry mtp ladedata? edit, lenge siden nå men brukte endel 158 rainier som jeg ladet med N340 iht vihtavuoris tabeller. Brukte dataene for 158 speer, ser i Lapua tabellen over at de er temmelig like. (Godt å se at man ikke var helt på bærtur i starten av sin hjemmeladerkarriere ) Quote Link to comment Share on other sites More sharing options...
