i have a few pieces of federal brass for my 300 winmag that were resized and a little tough to get out of the resizer. I think I had to little lube on them. while having to put a little more muscle behind it to get them out the bases became slightly deformed from the case holder giving them a uneven lip on one side, about a 1/4 of the way around the base. it didn't actually tear the brass but now my bolt wont close with those pieces. I did file one piece to see if it would fix the problem, and it did. has anybody else experienced this and if so what was your remedy? Am I right in thinking the only real force that base ring gets is when it is in the resizer?
Thanks.
