[QUOTE="BUSTINDOGS, post: 2065370, member: 49798"] I did some digging and calculating and for a .224 caliber bullet in a bull barrel (1.2 straight no tapper) the barrel and lead bullet will contract the same amount. But what about bullet upset? the pressure behind the bullet should swag it to bore diameter. I'm not trying to prove that the bore being smaller is the end all be all, just trying to keep the thoughts rolling. Lots of things are changing, and lots of strange stuff could be happening...
