I keep getting bullets stuck in the pipe. I'm using a glock 23, probably 3000 rounds fired. I've had this happen with several different bullets, probably 5 times. Using a lee single stage, COAL 1.135 using titegroup accuracy load. The cartridge that sticks makes a pop in the breech and a flash but doesn't cycle (thank god). Also the case doesn't bulge like normal (stock, unsupported chamber) and is covered in black.
