ARE SUBSONIC ROUNDS QUIETER WITHOUT SUPPRESSOR PC

I still say in OPs case he's better off with a shorty 5.56/.223 upper. Maybe I'm just crazy (although I do plan to use supers for anything that requires killing stuff). 300BLK rifle and has no plans for a PCC anywhere in the future. With that said, I say all this as a guy who just built an 8.3'. All more than adequate for defensive purposes. Lehigh Defense claims an average of 1.2' expansion diameter for the 194gr ME. 45 JHP loadings show an average expansion diameter of. Expansion tests I'm seeing for modern quality 9mm and. 45 is going to be a lot more budget friendly (both for practice as well as defensive loads) and is going to give you performance that is very similar. When you can only afford to buy a few boxes (if that, since the LD stuff is $2/round) of quality defensive ammo, it's probably best to pick something with less expensive ammo costs (especially when you should be practicing with the thing you may depend on in a serious situation). No offense intended, but that's fucking retarded.

OP is talking about building this thing to use in a defensive capacity and then only purchasing a few mags worth of ammo for it. My point is, when it comes to doing this on a budget, choosing the platform that will give you the most quality options at the lowest price point is going to be the smart move. View QuoteWhile I'm sure the LD 194gr ME is a great projectile for the platform, it's one projectile. Still, roughly within an inch of the AMAX at 100y. Things start getting more lopsided towards the AMAX once you get past 150y, but then again, who's trying to use subsonic anything past 150y in any type of serious situation in the first place?Д®TA2: Just for shits and giggles, here's a drop chart for a 230gr Gold Dot 1050fps. I've now changed the zero distance to 50yd if you want to talk about a '100y and in' rifle. I'd imagine your hold under (with either setup, honestly) between 25-75 would be pretty large. Never really looked at it or thought about it. 300BLK rifle and just a generic chart for the drop out of a 9mm pistol is not going to tell you anything.Д®TA: And to be honest, I'm not even sure 100y would be a good zero distance for a subsonic pistol cartridge.

300BLK subs and whatever PC subs you're comparing or the drops are going to be way different. You have to make sure zero distance is the same between the. View QuoteHow far you're dropping at 100y is really going to depend on zero distance. If budget is as large of a concern as it seems to be in your case, OP, I think 5.56/.223 is easily the smarter choice, even if you have to deal with a 1'-2' longer barrel. 223 stockpiled already, so that lowers your ammunition costs for practice (arguable the most important part of employing any firearm in an offensive/defensive capacity), and to top it off, quality 5.56/.223 defensive loadings are significantly cheaper than their. Even with the slower velocities 5.56 reaches out of a 10.5' barrel, you'll still have a couple hundred yards inside the expansion envelope of most quality defensive loadings. Now, where the Blackout does rein king is in the ability to switch to supers, which are going to be ballistically superior to pretty much any pistol cartridge.ДЄs to OPs question, my recommendation would be to spring for a 10.5' 5.56/.223 upper and splurge on some quality factory expanding ammunition (like Fusion, Gold Dot, etc.). 300BLK does nothing better (at least ballistically speaking) than a subsonic PCC. Honestly (and this is my opinion, so it's worth what you paid for it), subsonic. Running the numbers through Strelok, comparing the 208gr AMAX loading to the 147gr XTP and 230gr XTP, all at 1050fps and zeroed at 100, they're all within an inch of one another out to 150y and within a few inches at 200y.

Even something like the subsonic 208gr AMAX load from Hornady (the 208gr AMAX projectile has a decently high BC) has a stupid amount of drop outside of 150ish yards when zeroed at 100. 300BLK, and velocities and weights (and therefore, energy) are very similar between the two.ДЄs for better ballistics, not really. You're essentially relying on the bullet poking a large enough hole (which is pretty much restricted to the diameter of the bullet, unless you're using an expanding projectile) to do damage.

Velocities are low enough that you're not getting much, if any, stretch cavity, so there's nothing gained there. View QuoteEnergy (at least in this scenario) really doesn't play a large part in wounding.
