I'm guessing the 147 was a bit softer but the 115 where very flat and quicker to follow up. Just my guess. Who knows he may have found a winning balance between weight and gas for his set up. I never went higher then 124s. 115 shot flatter at same pf. To me that was what I wanted

Big difference in muzzle rise, the 115's are flat with fast follow ups and the 147's feel like a factory gun, no point with the 147's other than practice.

OK So I went with a 115gr @ 7.14 autocomp @1.150 OAL and there is a noticeable difference. 5 shot average was 1526fps and my pf was 175 and some change if I did the math right.

The 147g @ 5.4 autocomp @1.144 OAL 5 shot average was 1177 pf of 173, again if I did the math right.

Any suggestion on 147gr 9mm? I'm running 147g at 5.4gr autocmp @1.122aol
