I'm looking at buying a Remington 5r milspec 308, it seems to come in 11.25 rate of twist. This will be a open field hunting rifle, will this rate of twist be good for 150-175 grain bullets? I'm looking for optimum accuracy from this gun, the best groups I can get out of it. I don't want to buy if it's not really made to shoot these bullets. I hope this makes sense, any help with this would be greatly appreciated. Please help me out, thanks. By the way my son handloads my hunting bullets, thanks
