I finally got my Grendel where I want, except Im still waiting on my can. I have the AA Entry Upper with 20 barrel, Rock River lower with fixed stock and Geisselle SSA-E trigger. The scope is a Leupold 4.5 x 14. This rifle is more accurate than I am and a blast to shoot.
I tried the American Gunner Grendel ammo in it yesterday. The group below is at 200 yards off a bench. The flier was called. Average velocity was 2509 fps with a SD of 23.84 and a 64 fps spread. At 200 yds the AG and 123 SST ammo shoot to the same point of aim. It is also lethal for groundhogs.
Unfortunately, this ammo does not like to extract from my rifle. The bullet lodges in the rifling when I try to manually eject a loaded round. Time to run it through my seating die to set it back a little.
I also chronod the other ammo I had on hand:
100 Wolf steel case ammo averaged 2757
123 AA Scenar ammo averaged 2697
123 Hornady SST averaged 2600 with an S/D of 17.58
