I took my Springfield .45 out while hunting last week to do some plinking. It has turned into a Jam-O-Matic. After racking the slide, the first round failed to load. I had to thump the slide with my palm to get it in. Almost every round after that was the same way out of the first mag. and about half out of the second mag. The bullets are hanging up half way into the chamber. It didn't used to do that. I'm shooting 230 gr. ball ammo made by American Ammunition Co., Miami, Fla. Any ideas on what's going on?
