That makes no sense. One hundred fifty yards?? Are you worried about trajectory??~MuirUntil I read this thread, I was thinking of loading 40grn rounds for my 1-in-8" .223's, instead of considering a .17 hornet for rabbits out to 150yrds, but it looks like I would have been doing the wrong thing.
There is no problem , in theory, asking a 223 to group 40g or 50gr bullets into small groups, but many shorter bullets could well disintegrate in the barrel or shortly thereafter if you push them too hard from faster twist rifling. A 223 makes a reasonably accurate 600 yard rifle in still conditions but it depends what you're after. If its long range precision shooting you're after, I would say that sporting 223 isn't the best choice as the BC of the bullets (look at G7 not G1) means even slight winds will result in wider groups than larger, longer bullets from larger cals. I do shoot my 223 at 600 and have shot moa with it in still conditions at that range, but that's still too much for precision work. I know that the bench rest boys do well at these ranges, but a hunting rifle may be a more difficult proposition for half moa at 600 yds.I shoot 32gr from a .204,50gr from a .222 and would like a .223 to shoot the heavier bullets. If it could shoot the 40gr and 55gr bullets as well,I could maybe sell the other two,just a thought.
My 1:9 CZ .223 shoots 40gr, 55 and 69 gr accurately with the 40s being best of all!I shoot 32gr from a .204,50gr from a .222 and would like a .223 to shoot the heavier bullets. If it could shoot the 40gr and 55gr bullets as well,I could maybe sell the other two,just a thought.
