With this pistol, we are actually a bit below the Minor threshold for IDPA & IPSC with the slower rounds. If possible can you relate to real world noise levels. Once again, this load was easily in the subsonic range - even when shooting with the Ti-RANT, which added 31 fps to the average velocity. Its quite simple to handload 223 subsonic ammo -using 55 grain bullets and pistol powder-but you would probably be better served with a 22 lr. What is the difference between shooting 300 Blackout sub sonic (with a suppressor) and say 5.56 in terms of noise. (Although, once more, subsonic 5.56 NATO and. To put things in perspective, a suppressed rifle firing subsonic 22 LR ammo will still issue a report of approximately 120 decibels. Obviously this will reduce POI but for arguments sake how worthwhile/feasible is it? 223 Remington, are traditionally supersonic and therefore less effectively suppressed. ![]() My question is could one(me), "modify" a bullet(calculating speed of sound vs relevent ballistic info) to make it sub-sonic? I mean like effectively I am keeping the same bullet, primer, case(padding with cotton on primer side according to ) and am just reducing the amount of charge. Now according to wiki, the speed of sound is 1130 fps, so roughly 1/3 the speed of the bullet in question.
