Let me tell you, with target loads, a squib that pushes a bullet two inches up the barrel will fool you with its recoil, that the bullet went out the tube. At a Bullseye Pistol Match, Old Joe shooting next to me, "fired" his first round, pulled the trigger on the second, but the 1911 did not go bang. Old Joe was pretty smart, he recognized a squib. I think he had to have racked the slide, and saw a fired case still in the chamber. I don't know the exact sequence as my pistol did not malfunction during the Timed Fire sequence. I only saw Old Joe beating on his pistol after he called an alibi. Old Joe had a 3/8" or so brass rod in the truck and beat the bullet out. The case was still in the chamber till I saw him knock it out with the brass rod. There were particle balls inside the case, making me wonder if a couple of grains of Bullseye pistol powder had been in the case. Others told me, a primer only could stick a lead bullet two inches up the tube.
