I have been hand loading for my 454 super redhawk for a while now and I have noticed that if I load any hotter than middle-of-data loads for my 300gr bullets I end up with brass sticking in the chambers. I also have the same problem with my 14" S&W 460. I use starline and hornaday brass in both guns.

I have reviewed my load data over a chronograph and feel that I am not into dangerous pressures especially when you consider the sheer strength of the super redhawk.

Both of these guns are hunting guns for me so terminal energy is important to me.

I have noticed that both guns have tool marks in the chambers and I feel that in order to achieve top loads with easy extraction I need to do something about these tool marks.

My question is what methods can I use to smooth out or polish the chambers with out causing them to become oversize or have ripples in them?
