The truth is, there’s a time to slow things down and keep it quiet, which is why subsonic ammo exists. Not only is all that velocity-crazed volume hard on the eardrums, it’s also unfriendly to the pocket book, as anyone who has recently bought a box of ammunition for one of the newest long-range super cartridges can tell you. Just stand next to a muzzlebraked magnum or a straight-piped hot rod to get the picture. The drawback, however, is the noise pollution that accompanies our fixation with speed. From muscle cars to overbore rifle cartridges that burn barrels and launch bullets downrange at well beyond 3,000 feet per second (fps), we operate on the assumption that faster is better. All the foregoing is strictly my opinion and I'm sure there are many who would disagree, but that's my story and I'm stickin to it.As red-blooded Americans, we’ve long ago come to embrace our ancestral need for speed. Subs are fun for shits and grins and impressing your friends with your suppressor, but for serious use and humane taking of game or varmints you are severely handicapped when using smaller calibers. Like real estate, location location location-bullet placement is key.Īll this summarized: By reducing your 22-250 to subsonic velocities, you will reduce terminal performance to a level considerably lower than subsonic 22LR HPs are capable of. Flat nose bullets will impart greater shock value, and the heavy bullet will retain enough energy to drive it deep. 30) then you can load a heavy bullet and have a much greater effect on game. Now, if you decide to go with a larger caliber (at least. If that's not enough, the bullets that are designed to be launched at 3000+ fps may not stabilize well at such low velocity and cause baffle strikes. Also, the POI is about a foot low from normal at 100 yds, whether it be 223 or 308. My suppressor works very well at reducing muzzle blast, and the supersonic crack is about as loud as an un-suppressed 22LR with high velocity ammo. Since this test, any animal shot with a jacketed bullet is shot with a full power load around my house. Hitting tissue rather than water may well cause a greater upset in these bullets, but I ruled them out after the water tests. If you HAVE to be quiet, I would put much more faith in the subsonic 22LR HP than the 224 dia Vmax at subsonic speeds. First jug blew up and the bullet separated into 3 equal slivers, 2 of which remained in the first jug and one penetrated into the second jug. The CCI SEGMENTED HP subsonic performed just as designed as well. The bullet went on through the second jug, which had a 3" split at the entrance hole, and punched a neat hole in the 3rd jug where it stopped. The HPs mushroomed perfectly and the first jug exploded like it had been hit with a 223 full house load. Many animals react like they were struck by lightning and are DRT with these fast bullets-but slow that bullet down and the magic is gone.ĬCI 22LR subsonic HPs, on the other hand performed admirably in the water tests. And velocity is what makes these small calibers shine. This is not to say a well placed round won't kill, but you completely lose every advantage of having a high-velocity round when you go subsonic. Most any jacketed bullet designed to leave the barrel above 2000 fps will not mushroom or otherwise perform like it is designed to do at 1050 fps. It was not deformed at all except the engraved rifling marks. Punches a hole through about 3 jugs and stops in the 4th-and I could probably re-use the bullet. I fired several into 6 milk jugs of water lined up. I can assure you the Vmax WILL NOT PERFORM at subsonic velocities, at least not in water tests.
