I have a 204 and a 223 Fluted, both will shoot 1/2"-3/4" groups...........going out tomorrow and have some fun with them, and my new AR16 223, which has a 1:7 twist. I was happy to find that the AR will shoot 1 1/2" groups with the WWB 45's and 1/2" with the 62 grain rounds.With the 1:7 twist , I was wondering about the 45-50 grain rounds. You will really enjoy ur 204 Fluted, a real sweet round and an excellent rifle.
