Best I've experienced is 70 gr Sierra BTHP Match, however I had approx. 1/2 MOA @ 100yds with 80 gr. I think it just depends on the rifle as a hole, because I've used 73 gr in my 1/9 twist DPMS, after talking with the folks there.

I like high 60's grain bullets through my 1:8s. The 77's and 75's shoot pretty good.
Any of the heavy OTMs will work well. |

1:8 should shoot pretty much everything good. I've had two different 1:8 twist barrels and had no issues shooting 55, 62, 69, 75, 77 and 80 grain bullets.

This^^^ Correct. the 1/8" AR in my safe shoots very well from 55gr to 75gr (that's the range I've put through it). The 75gr worked best, followed by 60gr in a close second. |

I haven't had 1-8 that wouldn't shoot 77 SMKs very, very well. The only reason the military uses 1-7 twist is for tracers which are necessarily longer.

My 1:7 shoots the 77smk and 69 smk very well. For some reason I can't get very good groups with the OTM stuff....probably the shooters fault though :)
