[QUOTE="watersfam, post: 2214760, member: 118754"] Thank you The rounds I used were old factory Win. Super-speed (mistakenly id'd as reloads) and factory Win. Silvertips. My father who has reloaded since the 60's and still reloads quite a bit looked at the rounds that I was shooting and he is certain that the ones I thought were reloads were actually factory loads. I had one random Remington thrown into a single box, which caused me to think all of those boxes were reloads. Those are actually all 87 grain short Win. Super-speed soft points. These are considerably shorter bullets than the 100 gr. silver tips, which did not have any problems, so maybe they aren't setting deep enough and it may be a headspace issue. My dad also suggested using new .257 Bob brass or find some pre-formed .257 AI brass. I have not seen either on the internet and finding them here in SE New Mexico will be impossible. Only thing that is sold here is Brand new Hornady at $75 a box. Not sure my wallet can take shooting those to fire form them. My father thought he could pull the bullets and reduce the charge. While he has never dabbled in wildcat rounds, he has a good library of old books on reloading. He has an old book that mentions using a reduced charge, then cotton, then something like cream-of-wheat, followed by paraffin to fire form parent cartridges into AI cartridges. Is this the COW method you were talking about? [/QUOTE]
