Re: New barrel or set the chamber forward???????
Here is advice from my benchrest gunsmith: Examine bore with bore scope. If it is not severely fire cracked, and round count is not high, re-bore. If the round count is high (my 6PPC was at 1,200 rounds)its probably OK to re-bore, and you can expect to get another 500 - 700 rounds from it. Cost was $125. BTW, my re-bored Hart 6ppc shoots fantastic.
