shooting a 18" barrel w/1-10 twist, 168gr bullets, not getting the group I would like, would a lighter bullet work better, have tried 3 different powders.

You've tried three powders, but how manyn powder charges have you tried?

It's rare to see a 1:10 twist .308 not shoot a 168 gr.

Whish 168gr bullet? Smk? You may need a different length bullet to get it stabilized out of the short barrel

What powders and what charges? That barrel should be fine with a 168 grain bullet.

Barrel length does not dictate stability. Twist rate, does.

Or at least tell us what you did to correct the issue. We are all willing to absorb information. wink

They stabilize by running faster twist. 1 in 10 will stabilize a 208 amax at 308 velocity. Slow it down to subsonic and you will need a 1 in 8 or 7 to stabilize it. Its a combination of velocity nnd twist to stabilize a bullet.

Please provide details about the rifle, scope, and what ammo combos you have tried, and the results for each.

Twist rate is not the issue, and that is a certainty.
