My 6BR is in the hands for the gunsmith. Just waiting for him to finish.I wouldn't buy another 22-250. As long as your going to spend a lot of money i would buy a caliber that's known to be very accurate. My 6BR 14 twist will shoot 58 gr bullets a little over 3600 fps without signs of pressure. Also have a 6BRX I have not shot very much easily get over 3700 fps no pressure. Krieger barrel 0.030" free bore. Would get zero FB 12 twist if I bought another barrel. It's a Rem 700. With just a few trips to the range with the Sierra 60 gr Varminter I have shot 1 group in the 1's and several below 0.250". No struggle to shoot just about any load under 0.500".
