I’m sure just about everyone has heard of Hornady’s XTP bullets and I have always found them to be good performers. They may not be the “best” but usually give deep penetration with modest expansion.
Shooting five rounds, from the Sig P229, gave me an average velocity of 932fps with a high of 938 and a low of 927fps.
When shooting the Kahr Mk9, I got a five shot average of 884fps with a high of 901 and a low of 873fps.
Shooting the first round from the Sig P229, into the bare gel I got a velocity of 941fps with a penetration of 18 inches. The bullet had a recovered diameter of .54 inches and a recovered weight of 146.9 grains. The second bullet penetrated to 19.5 inches with a recovered diameter of .54 inches. The bullet’s recovered weight was 144.1 grains and the velocity was 951fps.
When shooting through the heavy clothing, the first round form the P229 had a velocity of 944fps and penetrated to 21 inches. It’s expansion was .49 inches and the recovered weight was 146.8 grains. The second round had a velocity of 936fps and penetrated to 23.75 inches. Recovered weight was 145.7 grains and it expanded to .48 inches.
