I have an 8lb all in Rem 700 BDL in a Kevlar Brown Precision stock with 20MOA rail and 4.5x14x40 VXIII, Timney trigger, 24" barrel, Harris Bi-pod.
The rifle will easily hold .5MOA HOWEVER, it is so light that it really takes patience in setting up for a field position
shot. If you don't consciously think about
1) push forward / pre-load the bipod.
2) Relax trigger hand from ANY side pressure.
3) Just the right amount of Cheek pressure
4) oops, animal moved a little, start at #1 again
If you don't really really focus on the shot, you could easily shoot 2MOA+ at distance with a rifle this light.
The added weight of a 11-12lb or heavier rifle makes an enormous
difference in shootability; especially when NOT shooting off a bench.
BTW: shooting a 160AB and 162A-Max with Norma brass and RL-22. Best group is 5 shot group of 5/8" CTC at 200yds. 1/2" at 100 is easy from the bench as long as you keep the barrel reasonably cool.
