He finally did it. Loaded some Federal HST's to very hot levels, then chronographed them.
180 grain from a Glock 27, 3.5" barrel: 1116 fps
180 grain from a Glock 23, 4.0: barrel: 1149 fps
Unsurprisingly, and I only say that because Murphy's Law is ever present and nothing is written in stone when it comes to ballistics, the 3.5 inch gun returned bullets expanded to 1.09", while the 4 incher stopped dead in its tracks at .94 when fired into a modified Fackler Box using water baggies.
Jay makes no claims to accuracy, because even with a Ransom he cannot get two shots in the same zip code at 10 feet, so I'll be trying some of these first chance I get.
It should be noted that none of the recovered brass showed signs of distress, and his 2 weapons were fine after cranking out approximately 50 rounds apiece. His comment concerning recoil indicated that side by side firings of standard versus jacked loadings returned something of an extra push, but wasn't objectionable. He is using some sort of slow burning powder that he claims remains within SAMMI specfication for the .40 caliber bullet, but this would of course need be examined by a person or outfit that could actually run the genuine tests.
I've emailed Mike at Double Tap to inquire as to how interested he'd be in making some hi-velocity HST's in both .40 and .357, or even Ranger-T's in .357, and am awaiting his reply.
Bottom line remains what we've believed to be the case all along. IT SEEMS possible to get 5" performance from a 3.5" handgun with the best modern ammunition available, and thats all it's ever been about to begin with. After this it's on to .40 cal carbine work to see just how fast these baby's go when cranked through a 17" barrel.
