Been lurking awhile. Been shooting the same rifle for 24 years and want to stick with it. Shot the barrel out of it so I paid the lowest bidder to hang a new shilen barrel on it. I asked for a tight chamber and 1/9 twist. Received a 1/12.5 freebored barrel. SUCK! NO recourse to take on the gun smith. Needless to say I want to start over. My research indicates I should go with a 1/8.5 twist but hart only offers 1/9 or 1/8. This gun will only see 160-180 gr loads and I want accuracy to 600 yrds. Any one have real life experience that could help me decide what to do? After spending good money on my trusty rifle I want it to stand out in my gun collection. Hart offers a skip twist flute, but I want to maintain a high gloss blue finish any suggestions? Hart doesn't advertise CM. Any other input would be appreciated. Every other gun I have I can dial in through hand loads. This is my first rebarrel and don't want to screw up again.
