I've read that subsonic rifle loads usually use pistol powder, and usually only around 5gr of it.ĭoes anyone know the best powder and charge for 75gr subsonics? I've got a bunch of H335 that I use for 55gr full power rounds. I'll be using bulk 75gr HPBT bullets from wideners and wolf SRM primers. 223 suppressors, which is what I'll be shooting my subs through. But even for those applications (SRT team taking out a streetlight quietly, etc), I’d rather have a different suppressed/subsonic weapon one with more mass in the bullet.I've searched the archives, but every thread about sub. It would offer the ability to switch between “normal” and subsonic loads with just a magazine swap avoiding the swap to the Ciener kit, so I suppose it might be practical for some very specialized applications. My point is, I don’t know that I need more penetration than that and if not, what advantage does it offer…? The 20th lodged into the bucket bottom, where I pried it out. 22LR subsonic 40-grain solid, 19 out of the 20 rounds I fired went through 14 inches of water (a full 5-gallon bucket shot straight down into it), then penetrated the bucket bottom, and buried themselves in the ground underneath. Same caliber, same velocity, higher sectional density = more penetration. 223 subsonic is a very frangible design, which might be a bad idea with this low-powered (300 ft/lbs) of a rifle round, the only functional advantage I can see it offers over the. 223-diameter (.22LR) ammo at $0.038 a shot one one-hundredth the cost. 223 subsonics that cycled the action, but I’m not going to break any speed records running out to buy subsonic. The High Velocity round carries the full lethality of the Controlled Fragmentation characteristics of the NyTrilium composite, but is lead free, a substantial advantage in preventing your range from turning into a hazmat sight. The (ASP) Advanced Subsonic Round will reliably function the actions of M-4 and M-16 variants, both with and without the suppressor!! The Covert round is designed for minimum audio signature, one shot solutions and will not cycle the action, causing the corresponding noise. As a training round, it will not damage steel targets in kill houses. 223 cartridge that has reduced penetration in urban environments, and is used in close quarter anti- terror operations. The SRT (Short Range Tactical) round is a reduced velocity. 223 versions are regarded by many as the most effective CQB rounds on the market today. Lead-free, with all the advantages of the Advanced NyTrilium composite the. 30 caliber kill shots in excess of 1000 yards. As a hunting round it is unrivalled in stopping power, with the capability of. In the magazine of a capable operator it can be the difference between victory and defeat. The lethality of the Extreme Shock round is beyond description. This remarkable achievement comes from a basis of technology and processes 10 years in the making. Made of the same revolutionary fragmentable Tungsten-Nytrilium Composite that Extreme Shock is famous for, these rounds offer stopping superiority as well as the reduced ricochet advantages. 223 munitions that will reliably cycle the action of both suppressed and non-suppressed M-4, M-16 and AR -15 variants. Extreme Shock makes rifle ammunition in most tactical and hunting calibers.
