[QUOTE="MagnumManiac, post: 2043949, member: 10755"] Winchester primer cups can be soft at times. I have a similar issue in my 25-06. I have measured the actual headspace of this rifle, it is .002” above minimum SAAMI spec. However, it flattens ALL primers even on start loads. I bump the shoulder for .001” headspace every time I size cases. This thing will shoot less than a 1/4” in certain conditions, but never more than 3/8” at 100. So I don’t tamper with it. Still has me perplexed why it flattens primers though. Cheers. [/QUOTE]
