Whenever I post a new test, on the several forums I post on, the one response comes up a lot is “I’ll stick with HST” or some variant of that phrase. There is a very good reason for that. The HST is one of the best, if not the best, performers in all of the calibers I have tested it in. This is the first complete test I have done in the .45 ACP and I think this test, of the HST, will set the standard.
I got an average 5 shot velocity of 920fps with a high of 944fps and a low of 902fps. This average was 30fps higher than the advertised 890fps. Five shots at 10 yards were right at the point of aim and recoil was about what you would expect, not much different than most 230gr ball.
Round one in the bare gel had a velocity of 904fps, penetrated to 15 inches and expanded to .91 inches. Round two performed very similar to the first hitting the block at 927fps and matching the first round with 15 inches of penetration and .91 inches of expansion.
The two rounds fired into the heavy clothing covered gel was very much like the two in the bare gel. The first round had a velocity of 921fps and penetrated to 15.5 inches with an expansion of .82 inches. The last shot traveled at 910fps, expanded to .83 inches and penetrated to 15.25 inches.
I often get asked to post pictures of the gel after I shoot it. I normally don't because they just don't turn out very well or the block is getting dark from remelting. This block has only been reused once I thought I would give it a try.
Here are the first two rounds in bare gel.
With the two rounds through heave clothing.
