I was always under the impression that free recoil reduced velocity. However today I was testing shooting positions free recoil vs shoulder touching and trigger finger and nothing else. Load was 30.4 grain varget in 6br with a 105 hybrid Berger, lapua brass and cci 450. I know this is a fairly stout load and with my shoulder on the butt pad I was getting 2920 fps with standard deviation of 5.6 and max spread of 12 which I was fairly happy with. It created a .56" group and a .6" group at 200. When I tried free recoil to see what would happen with the exact same load I got an average velocity of 3040 with one even reaching 3085. Max spread of 87 and standard deviation of 40. Of course the group was worse but still about .75" at 200 yards. I can understand why the spread could be higher but how could it add so much velocity? Every shot with free recoil was over 3000 fps. Any ideas?
