[QUOTE="Trickymissfit, post: 780977, member: 25383"] the barrel twist rate is the important factor here, and not really wether it's a 22-250 or a .223 or .222. Have not shot a 14 twist 22-250 in many moons, but the last one I shot did half inch groups with bagged Remington 55 grain bullets that you buy in bulk! Have no idea what the load was, but guess it was around 3400fps. The rifle was a 700 BDL with a 12x scope on it. All my 22-250's have a 12 twist barrel, so can't compair the three that I own right now with a 14 twist rifle. But on the otherhand I have a .222 with a 14 twist barrel and at least two .223's with the 14 twist barrel. The .222 will punch .60" groups all day long in a hand gun (15" barrel @ 2700fps). I think that one is good for about .50" groups if I'd just setdown and work up a serious handload. My Remington 700 has a 20" barrel in .223. Has only seen about five different bullets in it's life span, and the worst was about 3/4" groups (all my groups are five shot). Like I said I use the Hornaday Vmax for groups in the mid fours.
