My Lilja barreled PF built upper in Grendel is usually a 3/4" shooter with handloads, occasionally 1/2" with 5 shot groups. This is from a Caldwell front rest and a Protector rear bag. Free recoil works well on my bolt guns, with an AR I have to really hold it firmly through the shot and bolt cycle to get decent groups. With factory ammo it was usually a 1" shooter, AA Lapua was the best factory ammo across 4 Grendels. My experience has been that bolt guns offer the most accuracy across 4 calibers when compared to AR guns.
