Question for k kommandos. I'm getting my second AR 15 a

That's actually a really good question. You're probably going to have to jump into a dedicated forum for that, there aren't many .300BO guys around here right now.

Most of the projectiles look like they suck because they are made to handle 300 win mag velocity. 300 subs really need a bonded pistol bullet design and there are like 2 companies that do that and they aren't cheap...

Any 300BLK load with TAC-TX bullets should be fine. Subsonic is only good for suppressed shooting, since the ballistics are equivalent to .45 ACP. I keep my pistol loaded with Barnes 110gr in transluscent Lancer mags. I am paranoid about getting my .223 and blackout ammo confused. Any mag should be fine for your uses.

>Equivalent to .45 ACP
Got a sauce for that? I'm new to .300 BLK as well

Equivalent mass and velocity with smaller frontal area. I really don't like shooting supers out of my 10"pistol because they are super blasty even with a flash can. Also they shoot giant fireballs... Right now I'm going with 208gr hornady bthp loaded up to 1400fps since I don't have a suppressor. Lots of energy and quite a bit less concussive. I don't know if they will ice pick through a target though.

subsonic .300blk is a total meme. its hard to make a gun thats reliable with both subs and supers. inside of 30 meters .45acp is ballistically advantageous, if only slightly, over .300blk subsonic.

I can't stand that one. I upgraded to the model that replaces the vice clamp

Do you have evidence to support this claim

> how reliable are the heavier rounds in ar15 magazines, pmag drum mags etc...
not very. many larger rounds have an ogive which will interfere with the guide rib in just about every magazine, including PMAG gen M3s. You can usually only fit in 5 or 6 rounds before they start binding or bulging the magazine. Some people have taken to sanding down the guide ribs, I've simply stuck to shooting supers. However, I have this trouble when loading plinking loads with cheap Speer TNTs. I have to load rounds with a COAL short enough to fit in my magazines. The point where the ogive diameter gets larger than .25" has to be behind the rib.

Store bought rounds often have 300 BLK specific bullets loaded to deal with the ogive issue. The closest thing I can find in bullets for reloading are Sierra Matchkings, but they much more expensive than Speer TNTs. Ammo availability for me has been hit or mostly miss. I can find it, but it's always in differing weights so my POI is affected. I can also find plenty online, but I'm not spending $1+/rd. and even 80¢ is a bit much. I have thus far reloaded all the 300 BLK ammo I shoot. Hexmag's newer magazines are good for my reloads, due to the thinner/more forward guide rib. Magpul is supposed to have released a PMAG specifically for 300 BLK and I am eager to get my hands on them, but AFIAK it is still vaporware at them moment.

there are several around, and many of your questions may have already been answered. You can also look to youtube, if they haven't yet banned gun videos.
