A friend of mine, a ballistician at, made a comment that recently caused me to grudgingly crack the door and consider the Blackout more objectively: “It’s the out there for combat.” A lifetime of gun technicana and a recent tour to Afghanistan backed his comment up. “What about long range,” I prodded. He looked at me as if I was an idiot. (Could be he’s right.) “That’s what designated marksman and snipers are for.” OK, in a team scenario, that made a lot of sense. The discussion continued.

“What about for individual use? It’s not very capable as distances stretch.”. Uses Modified.223 CasesThe.300 Blackout is a prime choice for extensive, inexpensive handloading. Because it uses standard.223/5.56mm cases, formed in a simple three-step process into.300 Blackout cases. (1) Cut the.223 cases off just below the shoulder with a Dremel tool, lathe or however you want to do it.

(2) Run the cut-off cases into a standard.300 Blackout sizing die. The die will form the new neck and shoulder. (3) Trim the formed cases to length (1.368 inches). All that’s left is to knock the burrs off of the inside and outside of the neck and load ’em up! Suppressor CompatibilityWhile you may not need a gun that shoots so silently all you hear is the bolt cycling, every red-blooded shooter wants one. Such loads are easy on the ears, perfect for popping marauding skunks in the back yard and enable nighttime hog control artists to terminate more hooved roto-rooters.

To get started, you’ll need to fill out the appropriate paperwork, order a.30-caliber suppressor and then twiddle your thumbs while the bureaucrats work out the red tape. You can make the most of the time waiting by loading up a bunch of rounds with 220-grain Sierra MatchKings or 208-grain Hornady A-Max bullets. Better practice giggling so that your stomach lining is conditioned to take it when you finally get the suppressor and turn loose those lovely oversize bullets. More Authority than 5.56mmA comparison of cartridges (L.-R.): 7.62x39,.300 Whisper subsonic,.300 BLK supersonic, 5.56x45, 6.5x38 Grendel, 6.8x43 SPC. Today’s premium.223 and 5.56mm loads get a lot of mileage out of the cartridge, but the.300 Blackout is designed to shoot 125-grain projectiles with energy approaching and even equaling that of the legendary AK-47 cartridge: the 7.63x39mm.

The very best.223 loads offer about 1,400 foot-pounds of energy; the.300 Blackout averages that or better and offers the benefits of larger diameter and increased mass—to the tune of about double that of the heaviest.223 projectiles that will feed reliably through a magazine. Instructors solution manual engineering economic analysis. Uses Standard M16 PartsOne detraction from other great recent AR-15 cartridges such as the 6.5 Grendel and 6.8 SPC is—no matter what the propaganda says—they don’t work perfectly through standard M16-type magazines and often need dedicated mags engineered just to feed them. Not so with the.300 Blackout. Since it’s based on standard 5.56mm and.221 Fireball cases, the Blackout has the same overall length as a 5.56mm cartridge. Also, the critical contours of the bullet’s ogive typically contact the feed ramp of an AR-15 in similar fashion to the 5.56mm, allowing it to cycle beautifully with standard M16 magazines.

As a nice little bonus, it also uses the same bolt, gas system—same everything but the barrel. Turning your worn 5.56mm AR-15 into a.300 Blackout is about as easy as a caliber conversion can be.

Best Reloading Manual For 300 Blackout

My buddy and I are learning to reload with a family friend. Of the cartridges we plan to load is the 300 blackout. Family friend had like 10 reloading manuals and recommended the Lyman manual.

The Complete Reloading Manual For 300 Blackout

So I'm looking at ordering 2 copies for me and my buddy. I looked online and the one he had, the 49th edition didn't have 300 blackout included but the 50th ed does. Only problem I'm having is the reviews for the 50th aren't too great. Could anyone recommend a different manual or vouch for the Lyman 50th edition? I may end up buying Lyman 49th ed and another with as much 300 blackout data as I can. Thanks & sorry for typos I'm on mobile. Thank you for checking your Lee manual.

I may decide to get the hornady 9th ed and then the Lee later. I have my plans pretty solid on doing 5.56, 300blk, and 9mm from the beginning when I get comfortable doing it on family friend's equipment. I know it's a lot at once but I budget well and he had the time and money talk as far as the wife goes and knows I fully understand that aspect. One thing question I haven't been able to get a straight answer was which book is just the most comprehensive. I guess that's why he has so many. Nosler and Hodgdon have it online for free.

Sells dedicated caliber manuals that are basically just photocopies of all the major manuals for those specific rounds, and their site shows they have a fairly new one for.300 BLK. I have the one for.300 &.375 H&H, and it contains the info from Hornady, Nosler, Sierra, Speer, Lyman, RCBS, Barnes, Swift, Accurate, Alliant, Hodgdon/IMR/Winchester, and Vihtavuori. Hornady's 9th edition has it, and I think Speer #14 does too, but all of that will probably also be in the Loadbooks copy (if you're only interested in the one cartridge). Don't touch Sierra - it hasn't been updated in over a decade.
