Ammo Inc's 180-grain TMJ runs 1,190 fps and 566 ft-lbs from a brass case, a power factor of 214 that clears the 165 major floor by 49. The total metal jacket encloses the bullet base, leaving no exposed lead, the point for an indoor range with lead rules. It is supersonic at the muzzle but slows to 1,065 fps by 50 yards. From a 25-yard zero the bullet is 1.2 inches low at 50 yards and 9.6 inches low at 100, still carrying 981 fps and 385 ft-lbs.

That puts it in the upper half of the 10mm ball spread. Fiocchi Shooting Dynamics 180-grain and Winchester USA Ready 180-grain both run 1,250 fps and 624 ft-lbs, 60 fps and 58 ft-lbs ahead, and each produces about 9 percent more recoil energy in the same pistol; the Fiocchi bullet drops 1.0 inch less at 100 yards. HSM Training 180-grain is 40 fps and 37 ft-lbs behind with about 6 percent less recoil energy. Federal American Eagle 180-grain is the soft load of the group at 1,030 fps, 160 fps and 142 ft-lbs back. CCI Blazer 200-grain gives up 140 fps and 76 ft-lbs at the muzzle, yet its heavier bullet lands within 1 percent of the Ammo Inc's recoil energy, and it drops 2.1 inches more at 100 yards.

Buy this 10mm Auto load for indoor range work where an enclosed bullet base is required and you still want near full-power speed. It is also a close practice match for Remington Golden Saber 180-grain BJHP, which runs 40 fps slower with about 6 percent less recoil energy. Shooters who want the mildest ball load should choose Federal American Eagle 180-grain, about 22 percent less recoil energy. Those who want the top of the spread should pick Fiocchi Shooting Dynamics 180-grain.
