Had my fav gunsmith use set of go nogo guages on my model 10 chamber...he says that its showing some wear and is a bit long. I have 2,500 or so rounds thru it after 3 years . Love the Mc Millian stock and accutrigger. thinking maybe just shoot it till barrel is gone then rebarrel and maybe new bolt....could have action trued up then also. So ..is this a viable idea or should I go get all new rifle?
