Here's a question for M1 shooters. I was shooting mine this weekend. I fired 24 rounds and the first 3 clips ejected normally, but the next 2 clips didn't eject. They were easy to remove, they weren't stuck, they were just sitting there and easy to remove. The weapon wasn't dirty or fouled in any way that I could see. I field stripped it today, everything seems to be in working order. Any ideas?
