.300 Blackout?

Ruger specs the RARR 300BO as 1-7 twist. Mine takes the AR mags, but doesn't necessarily feed long loaded rounds very well. Apparently I'm not alone in finding this as Ruger makes a singleshot conversion to get around the problem.

Maker makes copper bullets specifically designed to expand at subsonic velocities for that urban sniping with a can.
Lehigh defense used to market a subsonic expanding bullet for the blackout, but it wasn't on their website a couple days ago.

Glad you mentioned that conversion just ordered it because I have tried many different AR mags for the Ruger Ranch and none of them work very good.

Thanks for the info on maker bullets.

that 130gr speer and the 125gr. gold-dot are both good 'lower speed' bullets.
I gotta say, that 130 Speer has not been a low speed preformer for me.

I have taken three
Maybe four with it. Three I know.

One was shot twice (once with the Speer) My buddy hit a branch with a 125 sst (a soft bullet) and hit the liver. I shot the deer from 50-60 yards bedded between the eyes. That load is right @ 2050 15' out. The back of his head was a dime. No bulging eyes. Just hole in/out. Two thru shoulders was about same.

I have t used a 125 Gold Dot. But the 150 GD is a dandy @ 1850 ish. Very nice mushrooms. Recovered one from a Pig. I think pushed past 24/00/2500 might be too fast for it.
I know the 120g in the 6.5 made for the Grendel shouldn't have impacts past 2600 fps. I personally spoke with Speer engineers about it cause I shot a big deer with one @ about 2650fps. The bullet never exited. I got the deer but there was NO BLOOD & I was ON SNOW!! He bled good 5' from where he piled up.

Gold Dot bullets are 2 kinds, BO version expands down to 1400 fps but i found the 150s weren't very accurate pushed @ 2k fps. in 1:8 twist.
edit: The BO version is softer and doesn't like the higher fps. 18-1900 is plenty for deer but I won't use it for hogs.

i put the quotes there because low speed means different things.
the 30-30 will get it to 2400 without even half filling the case with powder.
the 0-6 would break 3-K without having to, well you know.
pretty much all hunting bullets are good if you keep them in their operational window.

I have followed the birth and development of the 300 BO from a hobbyist perspective. It isn't a caliber I've found a niche for personally, but it is still an interesting critter to read & learn about. Invest in? Not right away. Suppressors in Kalifornistan? Chortle, chortle, guffaw, guffaw.

As a nation we have spent 60 years with the 223 Rem/5.56 x 45 NATO. 3 generations of soldiers, sailors, Marines, and airmen have given the caliber a thorough test drive. I think civilian/citizen users have passed judgement as well, and it has been largely positive. Once controlled-expansion hunting bullets are added to the the caliber's features mix it becomes a very useful hunting tool, though care must be taken regarding bullet selection--most .224" centerfire commersh offerings tend toward varmint venues. Game bullets for critters larger than coyotes......Nosler Partition and Barnes often get the call.

Like the 30-06 and 308, all manner of wildcatting mods have followed in the 223's wake--to both the cartridge and its OEM housing the AR-series rifles. The 300 BO and others follow in that tradition. For now i am content to remain in the gallery looking on. It appears that my catheters in the right shoulder are getting removed soon, and I can think of no better way to commemorate my survival than to have another upper half built to fit atop my Aero Precision lower.

Never had an interest in< 30 cal for rifle, BO is cheaper to shoot and almost 30/30. Also does bunny fart loads better than 30/30. With the right powder you can run about any bullet that fits from sub to max fps loads. with hunting accuracy. Cycling is only real limit. Probably the cheapest general purpose rnd you can get.

I concur with CZ, the 5.56 is well established.

I don’t have a particularized dislike for the 300 Blackout, but I don’t have any great affection for it either. I understand the concept, but it has always seemed to me like something that was produced because we could and not to fill any specific need. Yeah, it works well with a suppressor, and it gets around the small caliber hunting restrictions of some states; but neither of those uses appeal to me. Doesn’t make those uses less valuable to others or wrong – just not my cup of tea.

it's intended purpose is to take illicit activity guards out at 75-100yds. without any drama or noticeable noise, so the rest of the guys can get inside the wire.
it just got re picked up for AR use 35 years later, and that's when the problems started.

if you want quiet and effective a muffler 3.5-4grs of red-dot type powder and a 230-240gr. bullet is about as good as your gonna get.

It shines as a defensive close quarters caliber. Cycles and performs head and shoulders better then the 9mm so many are enamored with. Very Supressable. Designed @ a 8.5" barrel.

"We" discovered it a acceptable close/short range hunting caliber.
"We" put it into rifles.

Completely undersatnd as in "that" reality it isn't as outstanding as most Don't supress or have need for a gun to defensively "clear a room". If we do the 12 ga or hand gun in bed side drawer are used.

When I became enamored I was shooting allot of 32/20 and wanted a bolt gun. My levers and single shots only took me so far. I know the caliber was"dead" but I loved it. This came along and I didnt see a ar-15 or a supressor. I saw a caliber that met ir slightly exceed ballistics and could be had in a bolt gun. I walked into a big Ruger dealer and on the USED RACK was this short tan/brown rifle as I grabbed the tag I saw 300 AAC. MY HEART FLUTTERED!!! I had read that these was not out yet yet here was a "used" one!!! I went straight to the counter. Counter guy was clueless. Finished and he got a state approval number and I went to register. About then another guy (employee) walked up and started talking and when he saw the rifle he went flush. Went to another guy and they both came to me. Now I had paid and had recipt and rifle.
I was explained that that gun never should have been sold. It was a pre production firearm sent by Ruger to evaluate. Someone logged and put it out. I said its exactly what I came in for and thank you for the sale. Just like when "you" bring a brand new gun back and the counter guy tells you they cannot take it back. I had done papers and they could not take it back. Of coarse we know the gun was released and no issues arose but that was my first 300 and turned out started a family of them I enjoy today.

A modern .32-20 sounds appealing, but I have other things that will do that. No interest in tacticool types of things, so if it doesn't efficiently throw heavy for caliber bullets I've lost interest now.

I understand.
But if the SHTF, I know about 100 people that are going to come to my house looking for a tactical rifle, pistol or ammo and most of them are going to be out of luck because they wouldn't buy at least one when I told them to.
IMO everyone should own at least one rifle chambered in the current military round. The 5.56 and 300 BO are just a barrel swamp away from each other.

Pretty much how I treated mine, using 98 grain through 170 grain cast and small doses of Unique and W231/HP38. Mine was a Handi-Rifle, so no magazine foibles, feed-issues, cycling problems, etc. Super-short light and indeed "Handi." Smaller than my Red Ryder BB gun.

Cheap (actually "free" at the time) brass, small powder charges, efficient and accurate. The gun was a hoot. I went 'round and 'round when trying to choose my ONE 30 cal, playing with the 300 BLK in the Handi, 7.62x39 in a CZ 537 Carbine and the 30/30 in a Contender Carbine. Really sort of a tough call, but then again a no-brainer. For ONE 30 cal., the 3030 won out, but I do still appreciate the other two a great deal.

If someone were subsistence-hunting and knew (or could admit) they'd be shooting small game most of the time, with the occasional "close-range" deer, it would be a very workable cartridge. I say this ignoring the AR platform too, so bear that in mind. Did my time with those and over them. I'm much more interested in single-shots, levers and bolt-actions, depending on the cartridge, so my experience may or may not be as useful to those using ARs.

For subsistence hunting, shotgun wins every time. .22 LR would be second.

As for SHTFscenarios, if it's ever more than I can handle with a pump shotgun and a lever action rifle and a .357, guess I'm screwed and I wouldn't want to live in a world that's gone that far to hell anyway. Not gonna let paranoia rule my life. I do agree eveybody oughta own a few things chambered in military cartridges and a bolt action .223 is simply too useful not to have a couple, so I do.

12-gauge pump shotgun and a bandolier of buckshot shells is about all a person realistically needs for home defense...or will be able to use before they get overrun in a SHTF scenario. I'm not going to sit in my armchair dressed in level 4 body armor with my helmet and decked-out AR sitting my my chair just waiting for the end of civilized society. Anybody F's with my house they're going to get a rude surprise and better bring more than eight friends if they want to win. I guarantee I can do more damage in five seconds from my front door with a Mossberg 500 than with any AR. For patrolling the property, a nice, light, basic AR-15 carbine chambered in .5.56x45, with a suppressor to save on the hearing, is really tough to beat.

Personally for my country I would just reverse it.

Once upon a time I was interested in some of the tactical cool stuff but I came to my senses and realized that the harmless look, stealthily looking like a fat old guy which is getting much easier for me. Point is if a mob shows up I’ll do what I can but I’m not going to kid myself.

I love me some 32/20 WCF, and have 2 revolvers and a levergun so chambered. My 30 Carbine Blackhawk is a close cousin of the 32/20, as is the 327 Federal. If you turn down the velocity to the 900 FPS level the blasty eardrum drill aspects of the two latter calibers abate significantly; the 32/20 Marlin with loads in that pressure range yield about 1200 FPS and have a mild report; dial the loads back to the 1075-1100 FPS mark (rifle barrel) and they really quieten down.
