I have a 22-250 stock savage model 12 lpv and am thinking about putting a drop in shilen or pacnor barrel in a no turn 6mm BR caliber. This rifle will be used for fun non competion shooting @ 100 to 600 yards. Has anyone used any drop in barrels for accuracy on this type of rifle? Any comments or sugestions on the best brand of barrel, length of barrel, would be greatly appreciated.,I will be handloading for this rifle) Thanks.
