So I got the Bar-Sto barrel for my Sig 226 and it comes with 1:16 twist. The Factory 1:10 barrel shoots way better for sure. 115 grn group better with the Bart-Sto. This 124 grn has the best groups of any Atlanta ammo in my gun. The Elite 115 or 147 hp ammo is way nice shooting but has bigger groups. The 147 has less snap and recoil but has larger groups. This 124 in my Sig puts 10 rounds in a 2" square at 10 yards and most holes are on top of each other. Ammo is a bti expensive against other brands I've been testing. This is what I'll use for my competition events

Shot this against the 147. 124 has more snap and recoil. But groups way better than the 147. I'm getting a barrel with 1:16 twist and that may help. So far this groups better than anything I've bought from Atlanta Arms. Would like to see it softer shooting
