I shoot two Arrowhead barrel nut rifles, and one hankins, also one other Wilson barrelnut Arrowhead, I do have one heavier barreled Howa that luke
built for me a shoulder build,, the barrel nut barrels are all Brux 1 and 20 twist, the howa shoulderbuild is an 18 twist Krieger,, the only thing that has been done to these actions at least the remingtons is lapping the lugs, I know that you see the accuracy online of these rifles ,if I'm focused on my shooting all of these rifles shoot as well as any PPC or BR bench rifle that I've ever been behind, I have chosen to shoot the lighter barrel nut barrels and lighter loads,, for me the heavier barreled hot load rigs are for target shooting, just not practical to carry around and deer hunt with,,get a barrelnut barrel from Luke install it on a Remington throw it in a stock get some 300 grain arrow Max bullets from pitman load 59-60 grains of IMR or h4198 and shoot some bullets, you'll be addicted, if I were going to build another gun on a custom action shoulder build I would choose the one in 18 over the one in 20,, I personally think of 1 and 20 or 1 in 18 twist smokeless muzzleloader and some of the 300 to 325 grain bullets that are available is the most accurate bore bullet combination in America today that a lot of shooters have no idea exist, I think I've shot every 6 mil 6.5 22 cal ,, none of them outperformed the 45 Cal smokeless,, and no I'm not talking about thousand yard shooting,, I'm addicted for life
