>>27744567Depends on bullet design and, if you care, the testing media (they didn't use actual calibrated 10% ordinance gel, and the people who do this stuff professionally say that the clones of it -- like the stuff LuckyGunner used -- aren't as accurate. Clear Gel in particular has been known to exaggerate penetration). Traditional cup-and-core designs generally open up more the faster you push them.
Having said that, Lucky Gunner's testing results for HST show the opposite of what previous tests have shown. Here's some results on HSTs:
Fed HST 124 gr +P JHP (P9HST3) fired from G17 at ave vel of 1208 f/s; 5 shot ave below:
BG: Pen = 12.2", Ave RD = 0.64", Ave RL = 0.38", Ave RW = 123.8gr
4LD: Pen = 14.4", Ave RD = 0.53", Ave RL = 0.39", Ave RW = 124.1 gr
Fed HST 147 gr JHP (P9HST2) fired from G17 at ave vel of 1014 f/s; 5 shot ave below:
BG: Pen = 12.2", Ave RD = 0.63", Ave RL = 0.39", Ave RW = 147.5 gr
4LD: Pen = 15.4", Ave RD = 0.53", Ave RL = 0.50", Ave RW = 147.2 gr
