Frank, Try seating your non-lead bullets a minimum of .050" OFF the lands. Seymour

I have a Shilen 1-7 twist, 17 inch barrel on my 308 bc I made it to shoot subs but I still get it to shoot under 3/4 MOA at 100 yards when I shoot 168 gr. Amax and 165 gr. BT. ES under 15 fps. 43.5 gr. 4064, Lapua Brass, Fed 210 and ..030 off lands. I wish I could get the groups some of you guys posted but like I said I made it for different a reason.

Quick math in my head looks like you shoot 0.6moa at 328 yards and 0.4moa at 109 yards.

Even tho a 1.5 moa big game hunting rifle will always do the job, a 1/2moa rifle will do the same job with a bit more confidence

Exactly!
