One was the extreme spread and standard deviation, and the second was the powder charge relative to the case capacity. I came up with two ideas of why the failure. But, I did exhaust every idea that I could think of to get these bullets to work. I don’t give up easily and this was no exception. I can tell you this, I wasted a lot of bullets, primers and powder to find this out. I wasn’t able to make hits with any reasonable consistency or accuracy. At 300 yards or more everything just drops off a cliff. It’s amazingly quiet and extremely satisfying to hear the hit on a steel plate. Over all, at two hundred yards, it’s fun to shoot steel with subsonic ammunition. Wind deflection was not horrible, but it was not great either. They literally "mouse fart" kinda like a little kid's pop-cork gun.At 200 yards, I quickly noticed larger groups but it was still reasonable. Just make sure you have plenty of bullets - as it is so much fun. Manually chamber and viola!!!! Fun fun fun. Found a new 22 case and made that one maybe 1/8" longer than the one that stuck it and viola! I had it about right volume. I just clipped it off progressively shorter until I stuck one. I ended up using a cut down 22lr empty held with a bent paper clip as a dipper. or alternatively start at 8-10 grains and work down till it's quiet and fun. So for example - start around 2 grains of Uniqie/Red Dot and work up. You will absolutely stick a few while sorting out the load. Make sure you have a stout cleaning rod and a mallet handy to knock out squibs.Ĭheck the bore after EVERY shot. Take a teeny punch + hammer to knock out old primers and a hand primer unit with you. But a bullet which comes out of the muzzle at that velocity is spinning slowly, and is more liable to tumble or wobble.įor real low velocity work - your best bet is just to work up out at the range. If you could watch a point on its surface, it would be traveling in a much tighter helix. is therefore spinning nearly as fast as it ever did. But these bullets are still spinning as they land, and are usually well enough stabilized to land base-first.Ī bullet which has slowed from 2400 to c. In a vacuum it would regain exactly its muzzle velocity, but in air the terminal velocity acquired in its descent is so low that being hit on the head may do you very little damage. Most bullets take around a minute from firing to return to earth, a time of which much less than half sufficed for it to lose all linear motion. It therefore reaches a velocity of zero, and must spend nearly three seconds within sixteen feet of a particular point. An extreme example is a bullet fired vertically into the air. I interpret that, perhaps wrongly, because rotation just means rubbing against the air, but travelling a thousand yards requires it to elbow aside some four or five times its own weight in air. But a cartridge loaded down to those velocities isn't at all the same animal.Ī bullet keeps speed of rotation a lot better than linear velocity. twist was designed for 215gr., which gave long-range accuracy when the velocity had declined to the figures mentioned. Those loads might work, but I would feel more confident of accuracy with a lighter and round-nosed bullet.
