The Hornady Custom 10mm Auto 180 gr XTP (Hornady part no. 9126) is a 20-round box of 10mm Auto ammunition loaded with a 180-grain XTP (Extreme Terminal Performance) bullet. Hornady publishes 1275 fps and 650 ft-lb at the muzzle for this load from a 5-inch test barrel, and 1052 fps by 100 yards. It belongs to the Hornady Custom handgun line, which the company describes as loaded for shooters who want supreme accuracy and maximum knock down power. Hornady says every round is hand inspected before packaging, and that it builds Custom ammunition to give shooters the advantage of hand-loaded accuracy in a factory load. If your 10mm Auto firearm shoots this weight well, the published numbers make it easy to compare against other loads.
