I want to create a contender or encore 223 pistol with a short barrel manly for plinking out to 100 yds. I want adj iron sights for it also as I wont be mounting a scope. Which barrel maker would you people advise would be the best? Also are the short forends easy to come by as I want a barrel about 8 inches or a little less. I presume the contender frame would be lighter which I would want. What would be the optimum twist rate be for it40 grain up to 62 grain? One in 9? Also for an encore rifle( I presume a contender couldnt take the pressure) Who would make a barrel in 223 wssm? Any help would be appreciated as Im new to single shots Thanks
