I have a 25-06 varmit barrel and was thinking of renting a reamer for 25-06 AI. I have read one article online about this and it said you have cut off about 1/4" from the rear of the barrel. This was to make sure you are cutting a new chamber. But by cutting it off it makes it essential to refinish the rear of the barrel with simple hand tools.
The question is it needed to cut the barrel down?
Can I use the reamer at home successfully?
