Long story short - I sent my 1894 44mag off to have a new barrel put on it 16 1/4in and 1 in 20 twist. It has been gone a long time, however the little brown truck delivered it back to me today. Cleaned the barrel and slugged it. .430 with no constrictions. Most of the time it will be shot with cast.
The real question is - What is the best way to break in this new barrel? The old tried and true of shoot 1, clean for 10 shots, then shoot 2 and clean for 20 shots, then shoot groups of 5 and clean for the last 20 rounds out of 50?
Or just shoot 50 rounds through it to burnish the barrel, clean it down to bare metal and shoot my cast?
I know that it will not be an MOA rifle, but I do want good consistant groups at 100+.
