What are the options for a full power, hollywood suppressed rifle?

[teddy12b]

Short barrels are where the 300 shines, I have an 8.2" but I think the ideal is 9" for the most powder burn. If it didn't have that advantage, I prob wouldn't have built one and stuck with 5.56. Here's a good video about it.

This video referenced this video so I watched it. I think Travis Haley just sold me on the 300 blackout concept.

I'm afraid there really is no such thing as Hollywood quiet, especially in supersonic rifle calibers.

That is true. If you are just looking for quiet that won't happen. 200 yards and quiet. I don't think there is much that will do it, unless you want a bullet drop in 20 feet or so. Now if you want a full power round in subsonic without having to roll your own, a 45 acp is subsonic out of the box.

On the other hand the reason why our military uses suppressors, it makes the rifle quiet but the bullet is loud. Normally if someone fires a round and you are not looking at them by your ears you can tell where the shot came from. With a suppressor you can still hear the shot but will not know where the shot came from. I hope that was not to far off topic for you.

Took out my Thompson Machine 30 from SSNFA yeterday for the first time. This was my first suppressor experience and I really enjoyed it on my AC556. I was still using super sonic and would like to get something in 30 cal in bolt action. Looking at this thread, looks like 300 blackout is the way to go. Any specific recommendations for a rifle in 300 blackout?

 

[romad7]

I don't see a lot of benefit in a 300BLK bolt action unless you want it as an SBR. If you'll be using mainly supersonic then 308 would probably be a better choice. But, I'm also not looking to be as quiet as possible, I just want to be able to defend my house without anyone needing hearing protection. Any good bolt action would work if they make it in 300 or just have it re barreled.

I think 42769vette had a Savage bolt in 300blk with really good results. You might try to PM him about it

.458 SOCOM = deer legal in Indiana. Lots and lots of bullet choices.

I haven't shot subs from mine but 350 grain hollow points (~1700 fps) will hold 1.5-2" groups at 100 yards. I'm guessing a 500 grain sub would drop ~2 MOA from that zero and another 6-7 MOA at 200 yards.

Somebody on here posted a video shooting suppressed subsonic 458. I have not heard one in person though.

One of these days I'll SBR my 458 SOCOM and build a form 1 suppressor for it.

I like the idea of the .458 socom suppressed but I have not done it. I have done a fast twist 45-70 suppressed and it is cool with 500 gr. slugs. The .510 whisper or the .50 bmd are very powerfull and sub-sonic and 750 gr.Talk about a lot of energy !!! The drawback is that the bigger the slug the more noise it makes going thru the air. The .40 S&W carbines sound almost as quiet as 9mm.

FWIW, with a 25 yard zero my 11" Noveske 300BLK drops ~20 MOA (~40 inches, ~40 clicks on an Aimpoint) at 200 yards using factory 220 grain subsonics. That's a tough holdover with a red dot. Just something to consider when thinking about subsonic 300BLK, optics, and 200yd hunting....

I seriously doubt I ever take the gun hunting, I just like to know that it could. 20 MOA is a lot of adjustment. Have you ran that load through a chrony to know right where you're at? That's a whole lot of adjustment in such a short distance. Great information to know though.

 

[mammynun]

No, I don't have a chrony but it's held true for Remington and Gunn subsonic ammo from several different lots. I'm confident that it subsonic since it is pretty much Hollywood quiet with an SDN-6. Keep in mind that I'm shooting at a full sized Bobcat Steel IPSC target so I don't know exactly where it hits, but I do know that right around 20 MOA I start hearing the "ding" again, and I've never needed to adjust windage.
Supersonic 300BLK ammo from several manufacturers, with the same setup, does not require a holdover or optic adjustment to get repeatable POA=POI hits on the same target at the same distance.
Of course, if I zeroed at a somewhere further than 25 yards, the drop wouldn't appear to be so drastic at 200 yards... but my primary "use" for 300BLK is suppressed subsonic at "CQB" distances. A 25yd zero gives me POA=POI at 25 and 60-ish yards and I've verified less than a 3 inch deviation from muzzle to 90 yards and I'm down about 5" at 100 yards. People who typically shoot farther distances with subsonic 300BLK will/should use a different zero. I'll use a different caliber.

well, as that sounds about right for a pistol cartridge:

Personally, I dont' consider subsonic .300blk to be a "full power" rifle round... it's basically a low-BC .45 ACP (ie 230gr just under sound barrier).

Of course, if I zeroed at a somewhere further than 25 yards, the drop wouldn't appear to be so drastic at 200 yards...

you'd have to zero closer to bring it up at 200. My 9mm AR I have zerod at 75, which IIRC the first crossover is ~17yds. That puts it at ~4" under @ 100, and it drops like a rock from there. My 9mm is probably a little slower and lower BC than the factory subsonic .300blk.

See that's where I start scratching my head on all of this. Finding 9mm that's subsonic isn't going to be a big deal and reloading my own recipe would be a simple exercise. It's even easier to find subsonic 45acp and reloading my own would be just as easy as the 9mm. Those two calibers are more appealing because of the much cheaper ammo options, but they loose their appeal because of the lack of variety of rifle's out there for them that's reliable with reasonably priced mags. The 300 BO on the other hand has a solid base in the AR types, but the ammo is more expensive to buy and more a little more complicated to reload.

If/when I get this setup, this gun would be a shooter, not a range queen.

 

[OneBadV8]

Once you got the reloading setup and found a good recipe for everything though it would be pretty simple to load for it.

It you are pondering pistol calibers. Tom Denalls "Silent Destroyer" is a no brianer. It is sweet. I bought one several years ago. It is a .44 mag and you need to roll your own to get subsonic. With his suppressor the magazine write ups were getting a 1" pattern at 100 yards. I am not that good of a shot. Pull up "Silent Destroyer" on the net and there are a few things on it. Here is one I grabbed just now with a picture. You pull this rifle out and guys will be all over it. Especially the deer hunters.

Silenced 44 Mag Bolt Action - Shooting Sports Forum

Ammo is borderline subsonic out of the box in .44 special. Here is another quick link. The speed of sound is about 1050 Feet per second based on altitude and humidity. So look at the charts to get an idea on ammo.

yea, reloading 9mm/.45 is dirt cheap and easy. w/ .300blk you have either 1) expensive brass or 2) a lot of work to cut down .223 brass. I use the same load in my 9mm AR as my uspsa competition pistols, which is about $140/k for 147gr jhps @ ~915fps. if you use plated you could probably do it for not much over $100/k. Yes, metalform 9mm AR mags are about 5x as expensive, but you make up that cost quick w/ ammo costs.

there's not a lot of .45 AR options, but for 9mm if you're building the gun you have as much variety as any other AR, you just have to add a mag block.

If you cut down 223 brass, that's not something you have to do every time. Just until you get enough brass that you're comfortable with. I'd bet you could load .300 blk just as cheap as .223 though. There are lots of .30 cal bullets out there for lots of calibers so it's pretty cheap. And since you can reuse it many times, I don't see "expensive" brass or even the extra step of converting it the first time to be that big of a deal breaker personally.

Sure there is extra time in converting it the first time, but after that you can just reload like normal and reuse the same brass.

and this is why variety is a good thing.
I don't get spending any extra effort / cost for pistol cal performance, esp if I'm already set up to load pistol....
Usually when I load rifle on the dillon, I do two passes, vs one for pistol. almost double the effort right off the bat, not incl any special brass work....

Exactly, having the ease of loading bountiful straight walled pistol brass is a dream on a 550B.

 

[teddy12b]

Well guys, I think I'm going to be going the 300 black out route. I'm not saying that there's a stripped lower or a pistol build kit from PSA coming in the mail, but....... there may be some PSA boxes on my doorstep in the near future.

Basically what tipped me towards the 300 BO is that when I get a can for it, I can use it on a 308 as well. With regular AR mags that'll work for it, I've already got that covered. Maybe some reloading dies and brass, but since I already reload .30cal I have plenty of bullets on hand. Now, it's just a matter of waiting for just the right upper to show on PSA's website. I don't want to spend the $$ today, but this is basically what I've got in mind for an upper: PSA 10.5" CHF 300 AAC 1:8 SQR 7" - With BCG and Charging Handle - Barreled Upper Assemblies - AR-15

Ok, those of you who have following along on this, what are your thoughts on this upper? PSA 300 AAC 12" SQR 11" Pistol Upper NO BCG or Charging Handle
