good morning everyone. I am a new member at this forum. I presently own and love a Raging Bull .454 and a 9mm PT92. I shoot a lot of .45 LC rounds through the revolver and noticed the cylinder getting tighter and tighter. I cleaned the cylinder several times with a brush and lead solvent which I let sit for an hour. At first this worked. Now I can not seat a .454 bullet and close the chamber at all. I understand the concept of the slightly shorter .45LC causing build-up but I did clean quite vigorously. Any thoughts?
