I see the Hydra Shok being mentioned again in a few threads. Tested the myth that Hydra Shok will not expand when passing through cloth due to threads wrapping around the center post. I carry Hydra Shok in a few calibers, although some of the guys I work with hate this bullet. We tested a .38 +P+ 147gr, a 147gr 9mm, and a Gold Saber 124gr as a control load. They appear in that order in the pics. We used 2 layers of denim over wet newspaper at a range of 3 feet or so.
First pic shows zero expansion of the .38+P+. There was a lot of unburned powder left on the target at 3 feet, so I'm sure it burned very inefficiently. Shot a second round with the same result. Guns were a 2" Taurus and a Glock 26. No cloth noted around the center post, so it would seem the lack of expansion was velocity related. I was surprised at this result.
Second pic, no surprises, and no cloth around the post, although there was a little bit of thread on the bullet and the jacket edge. Guns were a 4" S&W 19 and a Glock 19.
Third pic shows some thread in the 9mm, but it still expanded. In .38 we used a 6.5" Taurus, a Glock 17 in 9mm. I think the greater expansion of the .38 is due to that longer barrel. Note the fragment missing from the Gold Saber. Again no surprises and no thread wrapped around any of the center posts. Busted.
All in all, not bad performance for an old-school premium bullet. Obviously the Gold Saber had no issues at all in the 124gr weight. Comments are again welcome, as are suggestions for the next subject.
