Solved from this product's advertised 2238 fps, 129gr bullet and G1 BC 0.485, with the sight 1.5" over the bore at standard conditions. Compare every zero for 6.5mm Grendel.
How to read it: filled circles are the near and far zero, where the bullet's path crosses the line of sight;the triangle is the peak (max ordinate). The shaded band is the 8" vital zone, ±4" either side of the line of sight. The dashed line marks the edge of the hold-dead-on window. The chart is zoomed to where the zero matters; the tables below run to 500 yards.

Product Overview
Alexander Arms 129-grain SST is a polymer-tipped 6.5 Grendel hunting load made for medium game. Alexander Arms loads Hornady's SST, a polymer tip over a lead core. It leaves the muzzle at 2,238 fps with 1,435 ft-lbs and has a G1 BC of .485.
Zeroed at 200 yards, it drops 12.8 inches at 300 and 36.7 inches at 400, where it is down to 758 ft-lbs. That is the most drop of the 6.5 Grendel loads compared, by a clear margin.
If you're cross-shopping, Hornady's Custom 123-grain SST is the same bullet six grains lighter and 342 fps faster, and from a 200-yard zero it drops 26.2 inches at 400 with 1,028 ft-lbs. AAC's Sabre Blade 123-grain Black Tip is 287 fps faster on much the same G1 BC.
- At 129 grains it is the heaviest hunting bullet offered in 6.5 Grendel
- A higher G1 BC than Federal's Fusion 120-grain at .340 and Barnes' VOR-TX 115-grain TAC-TX at .387
- About 5 percent less estimated recoil than Hornady's Custom 123-grain SST
- The slowest start of the 6.5 Grendel loads compared, and the least muzzle energy of them at 1,435 ft-lbs
- A lead core, so it is out where lead-free ammunition is required. Barnes' VOR-TX 115-grain TAC-TX is the copper bullet of the loads compared
