After loading hundreds of .38 spl at 4.4gr of win231 and 125gr berry bullets with winchester SP primers I have never flattened a primer.. Swapped over to fed. Champion primers and stepped up to 4.5gr and had some flattened primers tonight , not horrible but definitely flattened some Are the Fed. primers softer than the winchester?
According to winchester data I should be good from 3.8 to 4.8 grs of win231 with this bullet and at 4.4 it's kinda weak that's why I stepped up to 4.5 and you could tell it had a bit more thump.. Just wondering if the Fed primers are softer? Iam go a step back down to 4.4 and if it flattens them I know they are just soft but was wondering if you guys had run into this?? Or maybe they are hotter than the winchester? I have not BTW changed anything as far as coal..maybe just a tad bit more crimp but still considered light.
Thanks in advance...
