How far off the lands is best in the Grendel? AR frame.

Bout .010-.015, but you may have to play with it to find the best load. Of course you'll be limited to 2.300" C.O.A.L to fit inside of mag length.

Thanks.

Depends on the bullet you are using. The 123 amax works well at .010" but the 123sst seems to like .070-.080" jump.
