![]() In a small little CQB pit shooting at targets 10yds away the sonic crack can still ring your ears a little bit just because it's reflecting off the target so close to you. If you are using it on a 50yd+ range then you'll be just fine without earpro. Your suppressor will knock that down to hearing safe levels even if you do still hear the sonic crack. However with a 223 (particularly in shorter barreled AR's) there is a LOT of muzzle blast and that is what deafens you. Try subsonic 22LR in an unsuppressed 22LR and it's fairly quiet. ![]() Even with a suppressor most of what you hear is the sonic crack. With a 22LR in a rifle length barrel there is very little heard muzzle blast in the first place. Maybe I'm wrong, but I'd like to know why I'm wrong. ![]() I just fugured it would be the same type of deal with the. But use subsonic and it's as quiet as a mouse. 22 rifle it is just as loud as without the suppressor. Well, I know that when I shoot high velocity ammo in my suppressed CZ. Just shoot the damn thing and you will be fine. Why is it that when people get cans they immediately think that they need subsonic ammo? You wont find a subsonic round that is going to cycle the action of an AR unless you go to a 300 whisper or something of that nature.

The 223 is designed to travel 3000 fps and works great with a can, but if you want quiet either go with a 22 LR or build a whisper. I think of “Ball” as the cartridge type, and then define the bullet shape, material, etc.I hear you on the full power ammo with a can. It can be ball HP, ball FMJ, ball SP HP, etc. I think we tend to make these things more complicated than they are. To me, ball ammunition simply denotes a common bullet and loading, rather than a special purpose load such as high-pressure proof, tracer, AP, blank, dummy, etc. Also, I know many will disagree as we all like to use professional, technical language when required, but some credence must be given to common parlance developed over years of conversing about ammunition (or any subject) or we will all need to carry around glossaries to talk about the cartridge we shot at a target yesterday. There is always a problem when you try to apply certain, very restrictive parameters to a common term. Further, there are even ball loads with colored tips - Israel, for one, has used a color tip (silver) to denote ball 9mm ammunition of pistol velocity, as oppossed to SMG with no color tip, as well as a black tip on commercial ball ammunition intended for the Uzi Carbine. Even if one considers “Ball” must always be “FMJ”, which I do not, many companies make FMJ commercial ammunition. In the case of German sintered-iron loads, there is NO core. Lots of pistol ball ammunition has mild-steel cores and some rifle ammunition did, such as German S.m.E. I can’t agree that “ball” usually denotes, among the other things listed, a lead core. NATO term to describe typical FMJ ammo with all of the usual qualities of “Ball ammo” military surplus will also have ball-powder, whereas foreign ammo labeled as such from the past 50 years might have any kind of powder, but are just using a U.S. But all FMJ ammo is certainly not ball, since some FMJ ammo could be AP, API, Tracer, subsonic, match, etc… Most ammo labeled as “Ball” from U.S. The term FMJ just refers to anything that has such a jacket, and ammo labeled as “ball” is actually FMJ 99% of the time. “Ball” is usually the least expensive version of, and most mass-produced version of a certain caliber as intended for military use. And also, ammo labeled ball is usually the typical average load, and not Match, subsonic, lead-free, tracer, or anything else. The SS190 for the 5.7x28 has also been labeled as “ball” because it is the originally intended military load for the P90. Like I have heard of SS109 5.56 ammo referred to as “ball penetrator” because it is the standard military load for the M4 and M16’s these days. That’s not always the case though, as sometimes ball ammo is simply certain ammo that is originally intended for a weapon, and is the standard load for that weapon. Typical pressure (designed for standard rifles or pistols), Technical definition aside, I believe the term “Ball” has an implied definition meaning that ammo referred to as ball is usually all of the following:
