Reloading a 44 DE with H110 produces large fireballs
After 1800 rounds of 44, the small parts break/loosen up.
so far, had to replace a broken extractor, bolt stabilizer pin which stuck in the slide, and the firing pin stop which loosened up. the company sells an unlisted firing pin stop that has a nylon plastic screw threaded in so it can be tightened into the slot and not drop out under recoil. i removed the bolt stabilizer pin myself and stoned it/ sanded it a little to allow it to move freely. it must have imperceptibly peened itself enough out of line to stick. the parts are cheaper if ordered directly from MR so i ordered a new one and spring just to be safe.
Also, under recoil the screws holding the safety loosen up, so you need to use a small amount of locktite (I use purple)
and no, the rounds are not overloaded as i do not mix brass cases and weigh every round after loading. no pressure signs on the primers. i also changed the recoil springs around 1500, which was before the stop/pin issue
