Hi folks I'm currently trying to work up an accurate load in 223 using 75 gn Amax's using T3 tika tac 1:8 twist. I have already got very good loads using SMK 69 and 77gn bullets touching grou ps at 100 yds, even with my eyesight.
Tried varget and N140 and usual .5 mm off lands but cant get better than 1 inch plus groups.
Any ideas? std length or max length.
Regards Optomist
