![]() ![]() ![]() Note that I have no experience with subsonic 223 loads in any of my ARs. If you feel you need to go this way, I suggest the subsonic 77 grain Atomic load. Baffle strikes are expensive to repair, and Surefire can take a few months to get the can back in your hands.Ī subsonic 223 round will be quiet with a can. Maybe it will, maybe it won't, but I won't do it in my gun. You are taking a risk that bullet wobble will begin immediately upon exiting the bore. 308 bore suppressor that I use on AR-15s, however. I wouldn't shoot the 112 grain bullets in a 1/7 twist carbine with a 5.56 bore suppressor. Bullets often yaw more at the beginning of their flight than later, so it’s necessary to check for excessive yawing at very close range with a target material that will withstand the muzzle blast. “If,” however, is the operative word I assume (that word) that such a company wouldn’t make such a claim if it weren’t, but what would be your recourse if your suppressor were damaged? And keep in mind that confirming that the bullet is stable as it leaves the muzzle may be difficult. If this is the ammunition you are referring to, the description clearly states, “These bullets will not tumble and result in baffle strikes in properly aligned and sized suppressors.” If that is true, then there should be no problem with using that ammunition. The muzzle energy of the projectile per se isn’t something that affects whether a load can be used with a suppressor. How fast that happens I don’t know, but if it occurs before it can leave the suppressor, it will damage or destroy the device. That means if you fire such a bullet from your rifle, it will start to yaw greatly and begin to tumble in flight very quickly after leaving the muzzle. I don’t know what the twist rate would have to be to stabilize a 112 grain 0.224" bullet, but it would have to be faster than 1/7". As I recall without doing any research, 1/7" will stabilize conventional lead core bullets up to about 80+ grains in weight. The more common problem with firing very heavy bullets is because they may be too long to be stabilized by the rifling of the barrel. That should not be a problem with the load you’re referring to, based on my understanding. That’s why some suppressors are rated for how short the barrel can be. The muzzle blast becomes a problem when it is so great that it damages the suppressor in some way. There are usually two primary issues to be concerned about when using a suppressor: the effects of the muzzle blast gasses and the stability of the bullet. Can you provide a link to the ammunition you are referring to? I believe I understand what you’re asking about, but more details might be helpful. ![]()
