"M4 16" 1x7 4150 Chrome Moly Vanadium Steel, 5.56 chambered, air gauged, Bull Dog barrel with M4 profile."
I have several .223's with 1x9" twists and a Howa Axiom with a 1x12" twist... they are real tack-drivers with 40-52 grain bullets. I know that I can get up into the 70 grain-range with the 1x7" twist but, will it still do well with the 40-52 grain bullets? In other words, is the any disadvantage (with stablization) with the faster twist?
Thanks,
SS

You will have better stabilization with heavier projectiles in the 69-75gr range but should still shoot 62gr pretty well.
How about the lighter (40-55 gr) bullets?
Thanks.

They will work but they won't be as accurate, if you want to shoot the lighter bullets I would stick with a slower twist.

Unless your pushing the 40gr really fast i doubt you'll never see a loss in group size. :twocents: my 1in9 shoots the 40-60gr all well under Moa. I haven't tried anything heavier out of it yet
That's a good point actually and one I didn't consider but if using factory bullets heavier bullets will still work better.
demontang how far are you loading down with the lighter bullets? If so what advantage do you see or seek from it or is it just a case of shooting what you have a ton of?

Well the 40gr I reload have been max loads and some are middle of the road loads. I've shot the factory hornady 40gr vmax which are listed at 3800. I think the bullets of today you would have a hard time with trying to spin them to fast out of a 223.
The 40 gr loads that I'm shoot are listed at 3650 fps. So, there shouldn't be a problem with the 1x7" twist? :dunno:

I'll have to try some of the Hornady.
