I'm using Winchester brass I bought new in the bag. The bulges are 1/4 of the case length up from the rim and are easily straightened out with the resizer. What does 'web' mean?
I'm firing these from a Marlin 1894 if that makes any difference with chamber size compared to revolvers (I wouldn't think so). It might just a problem with the batch of brass since I've only found 5 or so with bulges out of 200 cases.
Thanks for all the input, I appreciate it!
