I went out today and fired 100 rounds. I was single loading them one after another. The first 50 were fine. After that, the shots just started slowly dropping down and down. I felt my barrel and I do have to say it was pretty hot. But I don't really feel it often enough to say that was the hottest it's ever been. I took it home and cleaned and it wasn't really that bad. I've definitely seen worse. I need some help cause I've never had this happen to me before.
