Thread: BA13 case head separation

I'm guessing either you got unlucky as I ran some pretty warm loads in mine (225 eld m loaded very long at 2450fps in Lapua Palma brass and never had an issue. I did here that the action could stretch (I did check barrel to frame gap with shims and it never changed running probably 100 rounds of that load before I decided I would stick with factory ammo for ease. Does seem odd though that both the go and no go gauges fit. There much resistance closing the action on the no go gauge. I'm sure a gunsmith will pipe in with an abvious answer.
