Last year when I fired this gun for the first time, I got mostly good results. But I also had 3 cases totally rupture just above the head.
Today I went to the range, with some factory ammo, as well as hand loads (both in standard configuration) but with the bullets seated VERY long and into the lands, or close to it.
My question, is my suspicion correct that some garage hack smith just ran an Ackley reamer into the chamber, without setting the barrel back?
