I have made brass centers for a 223 that won't go in with out some force. Need advice on what to do next. The pilot for the muzzle end is 0.223 dia and about 0.625 long. It starts into the barrel but gets tight about 0.25" into the barrel and I am sure it will go with some force from the tail stock. The same is true for chamber end only it is 0.377" in diameter and approximately 0.375" long
I intend to drill a 0.1875" hole in the chamber end pilot so that I can force the muzzle pilot out. I believe the chamber end will come out with a slight twisting motion. My Lyman Reloading Handbook says the straight portion of the chamber 0.20 long by 0.376 dia. I am confident the chamber pilot will come out easily once it is cut to 0.20 long.
Out of curiosity I mounted both pilots just snug enough to stay in the barrel then mounted it between centers, got 0.005" run out at the chamber end and failed to measure the muzzle end (lunch break). Will measure the muzzle end when ready to do the threading. With a 7/8 X 14 thread I am not sure what might be an acceptable run out if any. Would sure appreciate the advice of the experienced members of this website.
Have a good day
