Re: My 45 auto reloads are not chambering correctly! GRrrrrr
If you can see where the bullet is hiting the rifling, it's too long. Are you using the Lee mold xxx 1R? If so, the radius of the bullet is too "short". The wide radius bullet needs to be seated deep because the "fatter" ogive bullet hits the rifling. The xxx 2R with a gentler ogive, works better. You can try sizing your bullet a bit smaller, mebbe 451".
