Overall, I've super happy with the results. But, I wanted to test the bullets in MY gun with MY loads. Pretty cool, and lots of fun (was a GREAT conversation starter at the range!) but by no means an 'official' or scientific test. I have no idea what the temporary channel would be. The Lehigh path would take a cucumber to fill the hole, whereas the Hornady would take a small booklet due to it being a flat opening. But it looked to be roughly the same size path as the Lehigh, but more 'one dimensional' from the tumbling. The path also showed an area spread apart (wound channel) that I can only surmise is from the bullet tumbling. They penetrated the same depth into the gel, roughly 15 inches. Both the bullets was found backwards, meaning they tumbled when they hit the gel. They look like brand new, save the rifling marks from the barrel. And the results were interesting (at least to me) I actually shot 2, just for the hell of it. What would a Hornady 208 grain Hollow Point Boat Tail projectile do? Since the second block of gel was barely touched, I turned the sawhorses around and readied for a second shot, this time the 208g HPBT. But it's pretty easy to see it did not lose much, if ANY, of its weight. They are sold at 194 grain bullets, and the recovered weight of this one was 193.4 - and in all fairness, I do not know what it was before loading it. It penetrated roughly 15 inches of the gel - just into the second block. I was able to locate and cut out the was perfectly deformed, just as it should be. (Next time I'll take a tripod to use the GoPro) I wish I had a cool high speed camera to do slow motion, but I didn't even have room to set up my GoPro. It took a few seconds to find the bullet, and the path was a little easier to see. I found a neat little entry hole, and unfortunately the gel is not very clear, but an amber color. But I had to get up and check to make sure I actually hit the gel, it was so quiet and calm. There was not, so I let one loose into the gel. After verifying the sights with some 208 HPBT Hornady subsonic ammo, I tried one round of the Lehigh Defense to make sure there was no shift in POI. That proved to be a huge time saver, as it proved that it was also mostly sighted in for the 300blk at the same distance. I used my 8" 300BLK SBR with a SilencerCo Specwar762, and a Primary Arms, LLC red dot sight that I had on my M&P 15-22 that was sighted in for about 15ft due to some squirrel issues. My load was the 194g bullet, loaded with 10.5g of A1680 to a COAL of 2.185", using homemade case from LC brass. I had to transport it in coolers, but not to keep it from melting, but rather from freezing! It was a balmy 30 degrees when I was testing today but only 20 when I left my house. I found some recipes for homemade ballistic gelatin but I should note, this is NOT official ballistic gel, but rather kitchen gelatin made thicker, to *about* the 10% gel that the FBI recommends.Īfter making it up per the youtube vid and other online resources, and letting it set the required amount of time (day and a half) I took it out to the range yesterday. I wanted to test some Lehigh Defense, LLC projectiles but, at $1.50 per PROJECTILE, do they perform and expand as advertised? Unique powders optimized for subsonic use result in a low flash signature, ideal for either suppressed or unsuppressed performance.So. Silent and Stealthy: Hornady® Subsonic Ammunition doesn’t have the loud report of a supersonic round, and paired with a suppressor, it’s even quieter.Impact velocity of 1,020 fps into ballistic gelatin provides 16-18” penetration and 90%+ weight retention. Proven Performance:Performance of 300 Blackout Subsonic meets or exceeds FBI Protocol terminal ballistic test requirements.The Sub-X™ features a lead core and a cannelure for a positive case crimp for use in semi-automatics. Sub-X Bullet Technology:In addition to its patented Flex Tip®, long grooves in the gilding metal jacket of the 190 gr Sub-X™ combine with the bullet’s flat profile to ensure expansion.Performance of the Hornady® 300 Blackout Subsonic load meets or exceeds FBI Protocol terminal ballistic test requirements. Long grooves in its gilding metal jacket combine with the bullet’s flat profile and the patented Flex Tip® insert within its hollowpoint cavity to help it expand reliably at low velocities.
