View Full Version : 300 Blackout
Is anyone reloading 300 Blackout? I am about to begin on a single stage to get familiar before going to my Dillon. I am having a difficult time picking the grain bullet I want. Any advice or suggestions would be great. Will be using 12.5 AAC
Super or subsonic? Hunting or plinking?
For super I have been using Hornady 150 gr just because they sent me 1k when I got my LNL. I am not really a fan. I generally shoot a lot of Nosler as I pick up blems as cheap as i can get them. Because of that I have settled on the 220 and the 125. I think blk really shines in the 110-125 gr for supers and anything over 200 for subs. Over at 300blktalk.com there are guys that are definitly getting good subsonic results below 200 gr but for ease of loads I have choose to stay above.
I think at this point look at what powder you have on hand, I use 1680 for subs and litlgun or h110 for supers with good results, and try to find the cheapest projectile that matches with your powder.
What powder are you planning on using?
From AAC:
HANDLOADING INFORMATION
If you load your own ammo, pay special attention to all of the normal safety practices. Recommended powder for most supersonic loads is Hodgdon H110.
For subsonic, there are special requirements and nearly all published loads are non-optimal for the 300 BLK upper. Many existing loads were developed for Thompson Center® single-shot pistols, or for ARs by people not aware of the magazine limitations. These loads pay no attention to automatic rifle function and should not be used. Look for a load which results in a cyclic rate of 700 rpm or more. A1680 is recommended because its bulk density matches the case capacity and it will generate enough gas pressure to cycle the weapon.
Suggested subsonic load:
• R-P 300 AAC BLACKOUT brass
• Remington 7.5 primers
• 11.2 grains of A1680 powder (Adjust powder charge down as needed. Factory ammo is 1010 fps for 16" barrel)
• Case length is 1.368 +0.000 -0.020
• Sierra 220 MK loaded to 2.120 OAL (this length is optimal for reliable feeding from USGI magazines)
• Chamber pressure 21,100 psi.
I had decided on H110 for supers. I am still on the fence about sub. 1680 is what it is then! Where are you getting your blems

Google nosler blems. It's something you have to watch as they don't have them all the time.
For supers, the cheapest plinking bullets are 147gr M80's, or 150gr FMJ's. I think they were around $45/250 the last time I bought them around here. They can be found cheaper online though. But typically, a 110gr super will either be a very expensive hunting bullet, or if FMJ's, too short to feed reliably.
Be careful with Lil-Gun, there has been reports that it burns hot enough to get the metal in the chamber hot to the point of flowing. Literally melting your barrel inside. H110 is a much better and more popular choice.
I can't speak on subsonic as I only runs supers for hunting and plinking.
I have noticed that the mid range grains are the most available.
They are around. We just went through a bunch of labor day sales so you just need to wait on restocking. Keep your eye on this site - http://www.slickguns.com/category/reloading
Where is everyone finding bullets?
Just keep an eye out. Midway usually has 150gr Hornady FMJ's in stock. They are quite short when loaded to the cannelure, but they feed fine. I'm going to stop using them as soon as I use up my stash. A better option are the M80's (147gr pulls). I usually pick up a bag when I happen see them at my local shop. I'm in no big hurry to stock up since I don't use my 300BLK much, but they seem to work the best.
Wow, you're on a roll fluffing your post count! (Looks like the Mods took care of the issue)
Got the email from Widener's last night for the M80's on sale:
https://www.wideners.com/itemdetail.cfm?item_id=100001264&dir=
Thats a great price on the M80s from Wideners, Also look at 7.62x39 projectiles. I have shot many Hornady Zmax 123g projectiles through my blackout and they work beautifully. I have also used 150g 7.62.x54 FMJ projectiles as well. Midway also runs sales on Speer 125g TNT in a 500 count box. For subs you can get Hi Tek coated 245g projectiles from Missouri Bullet Company for 40 per 250 rounds. 300blktalk.com has a whole section devoted to blackout load data and projectile choices. Win 296 can be interchanged with H110. IMR 4227 is also a popular choice for both supers and subs. Look to Lehigh Defense's maximum expansion projectile for a sub bullet that will expand.

The optimal bullet weight for the 300 BLK is 110-130gr. The 147/150gr FMJs are being used because they are cheap and available. The 220gr SMK is the standard for subsonic. H110/W296 or IMR4227 for supersonic and #1680 for subsonic. IMR4227 can be used for subsonic as well as H110 as a backup.
Also look at 7.62x39 projectiles. I have shot many Hornady Zmax 123g projectiles through my blackout and they work beautifully.
I'm sure it works just fine, but I don't know if I would recommend it... 7.62x39 is .311" diameter as opposed to .308 in 300BLK SAAMI specs.

Yep. I did the research and read over at 300blacktlk about how well it worked so I tried it and decided it worked well for me. As all reloading info, use at your own risk.
