Aim at the shoulder, halfway up to the body. It will help to change the shot placement to hit bone. Adjust Shot Placement for Hunting with Subsonic Ammoĭue to its low impact velocity, subsonic bullets do not expand very well in game. Check your zero and test the Point of Impact out to 100m or more. It is important to note that bullet trajectory will differ greatly with subsonic ammo. All you can do is use it like a straight-pull bolt action rifle and pull the cocking lever back after each shot. If you semi-auto rifle does not cycle these subsonic rounds by itself, you can still shoot it. I suggest you then experiment until you get the heaviest bullet your gun is happy with. But, if your rifling twist does not spin the bullet fast enough to stabilise long, heavy bullets at subsonic speeds, a lighter bullet will provide better precision. Generally, heavier bullet in the calibre works best because they retain the subsonic round’s energy better over distance. It fires a 45-grain bullet at 1090 fps and is specifically designed for self-loading (semi-auto) firearms. If you do fire a semi-auto and have these problems with subsonic, try Winchester’s M-22 Subsonic. If you use a single shot bolt- or pump action, you will be fine. Subsonic rounds may have cycling problems for semi-auto rifles or pistils due to the reduced energy, and hence not enough power to cycle all the way. 22 Short will produce the same result, if your gun can fire them. ![]() A round with velocity reduced to 1050 fps has a decibel level lowered to 68, which is almost half of the normal high-velocity. 22LR with a suppressor, it becomes a very quiet small-game rifle.Īll major ammunition manufacturers have a subsonic load. 22 LR is more accurate because it displays 37 percent less wind deflection due to the disproportional increase of air resistance near the sound barrier. It is evident that the noise is almost none, but it does not make a huge difference in performance of the bullet on the target. 22LR round travels at about 1050 fps with 100 foot/pound. ![]() 22 LR performs at 1200 fps and 140 foot/pound of energy at the muzzle. Subsonic performs the best in rimfire rounds. Subsonic Rimfire Loads are Best Balance for Hunting That is reasonable performance at 5o meters if you hunt medium game, but is good for varmint at longer range where noise may be a problem.īecause the energy is reduced, the recoil is also reduced. 648, at 500 meters it surpasses the energy of a full-power 55-grain. More mass will allow you to compensate for less velocity like a bullet with a long, large diameter.ģ00 BLK subsonic 208-grain A-Max load from Hornady delivers 480 foot-pounds of energy from a carbine’s muzzle.īecause of this long bullet’s great ballistic coefficient of. This is a reason why you hardly see subsonic.
