NuJudge Posted September 1, 2014 Share Posted September 1, 2014 There was one batch of PMC .45 acp made something like 20 years ago, with small pistol primers, for no good reason. Everybody scratched their head. Right after the .45 acp non-toxic small primer brass appeared I heard the swithc was caused by breech face damage that resulted from large pistol non-toxic primers. A pox on whoever started crimping .45 and .40 brass. Link to comment Share on other sites More sharing options...
entropic Posted September 2, 2014 Share Posted September 2, 2014 Last time I sorted and tried to load 45 SPP brass, it was almost all crimped and impossible to load. Link to comment Share on other sites More sharing options...
Vincentaa7 Posted October 24, 2014 Share Posted October 24, 2014 love the fact I don't have to change primer cups from large to small on my Dillon press, wait two weeks to find large primers , Link to comment Share on other sites More sharing options...
shootsforfun Posted October 24, 2014 Share Posted October 24, 2014 Why dose a 6.5x47 lapua use srp and a 6.5 creedmoor use Lrp. I can tell you that I hate loading and I get to a spp 45. Link to comment Share on other sites More sharing options...
Steve RA Posted October 24, 2014 Share Posted October 24, 2014 You would probably have to ask the designers of the two cases mentioned to ascertain why they chose the primer size that they used. Link to comment Share on other sites More sharing options...
batex Posted October 25, 2014 Share Posted October 25, 2014 Someone evil came up with 45 SPP brass. Either that, or they get their kicks from frustrating reloaders.[emoji1] Link to comment Share on other sites More sharing options...
sfogold Posted October 30, 2014 Share Posted October 30, 2014 The sole purpose of the small primer is to mess up my rhythm when reloading 45s. One small primer in the batch brings my Dillon to a crawl... Link to comment Share on other sites More sharing options...
