A picture is worth a thousand words. I have been playing with this for a while it is that inconsistent radius that I believe is the problem. I have tried them in once fired several fired and brand new brass uniformed and not . In 45/70, 260 rem, 6mm rem, 270 wsm, and .270 win. If i really crunch them in there I can seat them. Normally I use WLRM in 270 wsm but I tried these primers in that brass just because. All the same results. #### primers to bad I have two thousand of em, five hour drive to take em back to the shop that sold them to me ha ha .
