Gun is a Ruger M77 in 6MM. Tang Safety model, heavy barrel.
Brass is assorted R&P and Winchester that came with the gun. Don't know the reloading history on it but doesn't look like its been reloaded too many times. In fact most of it looked like factory original single shot brass.
Currently in the process of working up some loads. Noticed when after being fired that when I went to FL resize, that I [beeep] near had to lean on the handle of my RockChucker to get the brass to resize. Much more effort than I have ever had to do reloading before. Also, large bulge out at the case head area. So much that I am afraid of getting case head failure.
I've tried re-sizing with both an RCBS FL Die and a Bonanza FL Die, same result. Also noticed some brass shavings at the base of the die when I remove it from the press.
Loads were starting to middle of the road using 80 Grain Sierra HPBT and another was using Hornady 87 Grain V-Max. Powder is IMR-4350 and CCI BR-2 Primers.
I can't tell if I have a headspace issue or just some weak, old brass. I do have some new brass that I am going to try for my next shooting session but this one has me a bit baffled.
This is the closest thing I can find online to what the post-fired brass looks like. (NOT MY ACTUAL BRASS)
