Armscor .357 Mag 158gr FMJ Ballistics
Brass Case • FMJ • MPN: FAC3576N
Solved from this product's advertised 1545 fps, 158gr bullet and G1 BC 0.170, with the sight 0.5" over the bore at standard conditions. Compare every zero for .357 Mag.
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 4" vital zone, ±2" 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 100 yards.

Product Overview
Armscor 158-grain FMJ is a full metal jacket .357 Magnum load, and Armscor names no particular use for it. At 1,545 fps it is loaded harder than anything else in the caliber, ball or expanding, for 823 ft-lbs.
Zeroed at 25 yards, it is 0.5 inch low at 50, the least drop of any .357 Magnum load, and it arrives at 1,371 fps with 660 ft-lbs. Recoil is in a bracket of its own, and a session with it is planned around that and not round count.
If you're cross-shopping, Sellier & Bellot's 158-grain FMJ runs 282 fps slower at 1,263 fps and 263 ft-lbs behind. Magtech's 158-grain FMJ Flat is milder again at 1,235 fps, 288 ft-lbs behind this load at the muzzle.
- 823 ft-lbs at the muzzle and 660 still at 50 yards, both the most in the caliber
- The flattest path in .357 Magnum, half an inch low at 50 yards from a 25-yard zero
- Ball at magnum carry weight with more energy than any expanding load in the caliber
- About 42 percent more estimated recoil than Sellier & Bellot's 158-grain FMJ, with no expanding bullet to show for it
- Armscor does not list this SKU, and the figure its US store publishes for the matching load sits under the 1,545 fps carried here
- The stored muzzle energy is below what 158 grains at 1,545 fps works out to, so the two figures disagree
