I have a good friend that is looking at putting together a LV benchrest rifle. i dont think he will travel to shoot many matches, but he will shoot out local fun matches. He asked me what chambering to have done, and of course i said 6ppc. He didnt even know what a 6ppc was. I then told him, how about a triple duce? He liked that idea much better as he had one as a teenager. I also told him that i have heard the 223 will shoot just as accurately as a 222 and that it just might be a little better at longer ranges. He said he didnt care what one we do but he wanted me to do some research for him on what one of these two chamberings would be best for the shoots we have. We shoot 100-300 yards in our local matches. I guess our question is, will the 222 be more accurate than a 223 by averages or will the 223 be the better choice with the added velocity? Something like that anyway. Whats your opinion? Thanks. lee
