Rebore a barrel aint cheap. I looked into reboring my shot out 270 wsm and was left with the question: why?
I think barrel making is as much art as science. And to me a brand new, hand lapped bore is worth the $150 more than a rebored hand lapped surface.
You do understand that $150 is all you're going to save over a new barrel?
And with a little careful shopping you could spend even less, cutting that savings to less than $100.
So I'm back to my original question: why?
All in all, its your decision, you pays your money and you takes your choice.
