300 blk

Anyone using a 300 Blackout AR? I thought about a 300 Whisper about 10 years ago, but never had a strong enough urge to build one. One of the reasons is my infatuation with wildcats went away. Since AAC has commercialized the cartridge, I am looking at it again. A buddy who is a LEO is building one on a NFA configuration with a can. Watching the videos of suppressed AAC firing and I am getting the urge to play again.

For those not familiar with the 300 Blackout (7.62x35), it's very similar to the 300 Whisper which is a .221 Rem Fireball necked up to .30 caliber. With 220 gr bullets, it can be loaded subsonic and is a quiet, sweet shooter out to 100 yards.

No.

I'm going for .458SOCOM. Rifle caliber bullets, sub and supersonic depending on bullet weight, and will go out to 200yds. I think in the right hands, and the right loads would do great out to 400+.

The lighter bullets shoot like a 45-70Gov. The haevies, well, are heavy.

Happy hunting with the 300 Blackout. What ever floats your boat. Enjoy the sport of building another upper/rifle. BRD (black rifle disease)

Re: 300 blk

I'm thinking about it now! I've got a suppressed 7.62x39 upper that shoots full power ammo great, but the EBR 220grn subsonics are all over the place. I've kicking the 300 whisper rebarrel idea around for a year or so. Now I've read this post and researched the round and think this might be a better rout to take.

There's a boy on Snipershide that has a Noveske 300blk upper for sale and I'm seriously thinking about it.

At the moment, I don't reload...which is why the 300 whisper hasn't come home. But now, it may just be time to start gearing up.

My good lady is going to take a stick to the both of us Damn black rifle disease.

Cheers,
Breeze

Re: 300 blk

Currently, Remington is producing factory ammo. It is rumored that Federal and Hornady will be releasing some also.

I think the round has grown on me enough that it will definitely be my next AR build. Probably not my next gun build but definitely my next AR.

Hmmmmmm, so I see that I'm not the only sufferererer of the Black Rifle Disease!

It's a terrible thing, but and a big but at that, unlike a crack head we have something to show for it at the end of the day....besides really dilated pupils.

Cheers,
SB

Re: 300 blk

I currently have a 300/221 barreled AR that I've never been happy with. I have ordered a 300 blk barrel to replace it. I'm just waiting on that barrel and then will try it out.

Re: 300 blk

What was the issue with the 300/221? What twist did you go with?
