Barrels come with several different numbers of grooves (IE 3, 4, 6) and there must be a reason. I have a shot out 91/8 twist remington varmint contour in 243. I mean chunks are missing and the throat is toast shot out. It had a hard life on the prairie dog shoots.
I have a Hart 3 groove 14 twist currently chambered in 6PPC. It has 550 rounds and I am thinking of rechambering to 243 for this rifle. If I push the 55-70 gr pills thru it at warp speed will it stabilize in a 3 groove barrel?
