I’ll try not to reinvent the wheel here but I have a question about chamber pressure and ammunition. I have a .264 BHW barrel and it seems adverse to the 120 gr MPT Wolf ammo, doesn’t want to eject, bulges in the web case wall junction, and the primers are flattened. While the 123 A-Max Hornady ammo runs fine.
Anyway something I finally got around to doing was mic the case neck on some fired brass it measures .2925 / .293 could the what seems like a tight neck even with reading at some point the chambering was with a .291 diameter be a contributing factor to the pressure issue and would opening up to the .300 size possibly help or even be feasible?
I’m assuming my barrel is at .295 but I haven’t tried to get a gage pin in it at this point.
Or is this just poor quality brass from Wolf?
Thanks for any and all input.
