Hi-Power Jack Posted January 29, 2016 Share Posted January 29, 2016 Each bullet, even if they're the same weight, might require a different OAL. Take your barrel out of the gun, and drop a cartridge into the chamber - it should "plunk" (goes in all the way) - if it doesn't, it may be too long. If it "plunks", it should spin freely and drop freely - if not, it may be (you got it), too long. Most likely cause of your problem - probably seated out too far.

mlmiller1 Posted January 30, 2016 Share Posted January 30, 2016 In your picture, the round with the lead bullet has a line around it near the nose. I suspect that is where it is hitting in the chamber but that is just a guess. The loaded one has the line, the plain bullet does not. Something caused that line! IOW, your round is too long for that bullet. MLM Link to comment Share on other sites More sharing options...

mannparks Posted January 30, 2016 Author Share Posted January 30, 2016 Well actually that is the line left by the sizing die when pushed on. The bullet is contacting the lands on the olgive of the bullet just be four the brass mouth about 1/8 inch. This same round will plunk on my 1911 barrel.

bulldog009 Posted February 2, 2016 Share Posted February 2, 2016 You may want to check your crimp as well. I know that has given me issues in the past with chambering hand rolled 45. Link to comment Share on other sites More sharing options...
