Ok so my second breech plug just arrived. what a difference compared to the first new one that was burred so bad. The second new was clean and in perfect shape. I anti siezed the vent liner very well this time and just snugged it for both vent and breech. i hope it still shoots like i last left it at the range.  |

Most of us tighten the breech plug pretty firmly. You don't want it coming loose. Snug is fine for the vent.

splinter, I tighten it up firm and give the handle on the fish whacker a swat with my hand. I think if the breech plug loosened any amount you wouldn't be able to close the bolt. If the bolt won't close completely you might get a misfire. I think the bolt handle cams the bolt face and primer ahead as you close it but Richard or Rossman could verify that.

Depending on how tight your headspace is, it could loosen a bit and still fire. You might experience some powder residue hitting the side of your face. It comes out that hole on the side and back at you. If it gets too loose, as DB indicated, you will not be able to close the bolt and that will not allow the rifle to fire. And yes, your bolt handle "cams" the bolt forward which fully seats your primer. You will note that if you stick a primer in the breech plug (with it out of the rifle) it does not go in all the way? You will note there is a slight bulge part way up the primer? When you cam the bolt forward you are compressing that bulge into the breech plug for a tight seal. If you look on the side of your action where the cam on the bolt handle that contacts it? you will feel a very sharp edge. I take a file and slightly round off that sharp edge. It will make your bolt closing go easier and cause less wear on the cam. Also, adjacent to the spot on the action the wood or synthetic material will usually also hit on the bolt. This also causes hard closing. Take That file and relieve it so the bolt can fully close without hitting the wood.

Rich is right, the gun can still fire if the headspace is loose. Petes first experimental plug was a little off on one dimension so the headspace was loose and primers would bulge slightly, by loosening the plug slightly I could shoot without the primers bulging.
