Why would my M14S stop ejecting? Couple of weeks ago I had it out, ran 20 rounds through it flawlessly - have had the gun three or four years and it can be picky with ammo but has always ejected with no problem. I've fired easily 1K of my reloads using IMR4895 and 150g pulled bullets. I ran t20 rounds, loaded another magazine, not one single round ejected. Bolt unlocked easily after each round fired single shot. Checked gas plug, was tight, disassembled and checked piston, was moving freely. Tried another magazine, same thing. Took it home, disassembled, cleaned, ect, ( I had one in basic training in 69 so no problem there), gun functioned fine. Loaded five rounds again using 44g IMR4895 and a 150g pulled bullet, CCI standard large rifle primer, went back to the range - same thing.
I've never seen/known it to happen, but can the gas selection switch change settings by itself? Should the slot be parallel or vertical with barrel?
thanks
