I'm looking for an AR to shoot across the course, I know this has been asked 100000 times before.
But. I'm looking for something to shoot bullets 60+ Grains or (70+ Grains). I have been told that 1:7 twist is the way to go. (Who sells a 1:7 twist off the rack?) Also, will a 1:8 be OK with heavy bullets bullets or not?
Bushmaster or what?

Thanks for the help, sorry for the stupid question

If you have questions of this nature, always consult the great Ammo Oracle.

60+ grains will be ok with a bushmaster 1/9 twist, when you shoot 70+ a 1/7 twist would work better, Colt would work there.

Bushmaster also offers 1/7 bbls. Just call them for availibility.

You could also get a CMMG upper with a 1/7 4150 bbl as well.

I just shot 68 Grain Black Hills Match out of my 1/9. Good groupings. I also went down to a 40 grain Nosler Ballistic Tip (Plastic) that also held good groups. Granted, the POI was about 6 inches off, but good groups.
