I picked up some 45lc 270 grain LSWC Keith style bullets, they measure.454 and are made from wheel weight lead, should I buy a swaging die to resize to .452 or will it fire just fine like it is. I could not push the bullet through the cylinder with some force, I stopped before I goofed up cylinder. Also I could not find load date for this bullet, anybody have some safe load data for it, for uberti revolver
