I can tell you free recoil Does Not work with a Kimber Montana in 338 Federal. When shooting my Barrett Fieldcraft or Montana I’ve found that holding them exactly as I would shooting offhand or kneeling works well. At the bench a rear bag and front rest help with stability, but I still hold the rifle the same. A bonus is that once you sight in at the bench it translates to the field perfectly. I don’t think you’ll ever be quite as consistent with a very light rifle, but the difference is meaningless in terms of hunting accuracy out to the most common ranges. When you walk up to your dead elk do you really notice whether the bullet was an inch off?
