SUBSONIC 223 USEFULNESS PLUS

I ended up separating out its niches into separate rifles though. I had actually almost completely lost interest in my AR before I built my 300 upper and it renewed my interest in the platform. I really really liked my 300 blackout because it introduced a lot of new ideas to me that I later expanded on. A 300blk hanging around for a quick trip to the deer woods, now we are talking. In a contender it’s as easy as swapping barrels, so again it’s a niche gun with a niche caliber in a niche role, but once you whack that hog in the thick mess you can use the same gun with a different barrel to go handle prairie dogs, or squirrel, or whatever. It’s something I struggle with having ARs because every upper I have has a lower underneath it, but for guys without that particular affliction you can have a nice or a really great AR and then slap a $400 upper on it and go from one niche to another while keeping your upgraded lower. Having a swappable barrel or upper makes the “gun” more usable to step out of that niche and into another than to simply put it away and drag out another gun. Realistically a person buying a 300blk is either looking at home defense, deer/hog hunting, or suppressed shooting, or a combination therein. That in itself is what makes me think that it’s the perfect round for 2 platforms, the AR and the TC Contender. Excellent expansion and 100% weight retention.ģ00blk is a very nice round for the niche it falls into, but it’s usefulness is questionable because of its limitations. This bullet was found in the chert behind the last armadillo I dispatched. I have dispatched a bunch of unarmored opossums (armadillos) with the REX on the hunting property. The Barry bullets are cheap subsonic plinking rounds costing me ~$0.31/rd to reload. On the right is the Maker 220 gr REX an all copper bullet designed to expand at subsonic velocities and has performed excellently for me so far. Left to Right: Maker 220 gr Rex, Berry's 220 gr Spire Point, Speer 125gr TNT, Barnes, 110 gr TAC-TX

Top: 16-inch 300 BO carbine Burris 1-4x24 MTAC scope, Bottom 9-inch 300 BO pistol, SBA-3 brace, Vortext 3X Spitfire, with AAC SDN-6 suppressor (will mount on either plus a few other firearms I have) Easy on the ears and with good bullets the terminal effects are more than adequate for what I need. It is a thoroughly enjoyable cartridge and firearms for that purpose. My 300 BO pistol is my truck/UTV gun when going out to the hunting property. I have two 300 BO but after building the pistol and getting my suppressor the carbine gets minimal use. For my use its primarily a subsonic cartridge. Been having lots of fun using it and reloading for it.

I was a late adopter of 300 BO and I love the cartridge. You can use that old 5.56 brass, which doesn't have them pesky steel cases and berdan primers ! They are a reliable 200 yard deer gun with 110 or 125 bullets, FROM A PISTOL ! Very accurate too, much more so than the 7.62x39 with any ammo I've seen yet. We are aware of the keeping them separate from 5.56 issue, it's pretty easy if you are careful as we are. I jumped on the band wagon with my own switch barrel AR rig. My son was first to adopt it as a motorcycle carryable deer hunting round in Oregon. Yeah it is a 200 yard round, but so what ? There really is nothing to compare with it in a pistol AR and that is it's niche and purpose. 30 Carbine load from an 7.5' barrel, which is amazing as that was designed and has a decent record as an antipersonnel round to 200 yards. 300 BO 110 load can and does exceed 2100 FPS so approaches 7.62x39 power from carbines It approximates the old. It also gives amazing supersonic performance in pistol barrel without crazy muzzle blasts. It was designed to excell in a short pistol length barrel and provide a heavier bullet with better short to medium range killing power at subsonic speeds. 300 Whisper we all knew it was a specialty niche round. Back in it's development by J D Jones as the.
