3oo blackout ballistic test
 
I thought this was a very telling comparison of different rounds in the same caliber. Plus i am very intrigued by this round.

I've been looking at the 300 blackout and the 7.62 x 40. They both use .30 cal bullets the only difference is the brass on the 7.62 x 40 is longer. I think im going with the 7.62 x 40. Also with the 7.62 x 40 you can use a .223 bolt. EDIT they both can use .223 bolts.

7.62x40 WT (16” barrel)
110gr: *2450FPS Muzzle Velocity and 1466 Foot Pounds of Energy
125gr:* 2400FPS Muzzle Velocity and 1599 Foot Pounds of Energy
150gr: 2200FPS Muzzle Velocity and 1612 Foot Pounds of Energy

5.56 Nato (16” barrel)
55gr: 3150FPS Muzzle Velocity and 1212 Foot Pounds of Energy
62gr: 3000FPS Muzzle Velocity and 1239 Foot Pounds of Energy
77gr: 2750FPS Muzzle Velocity and 1293 Foot Pounds of Energy

7.62x39 (16” barrel)
123gr: 2320FPS Muzzle Velocity and 1470 Foot Pounds of Energy

6.8 SPC (16” barrel)
110gr: 2550FPS Muzzle Velocity and 1594 Foot Pounds of Energy

300 BLACKOUT (16” barrel)
125gr: 2275FPS Muzzle Velocity and 1436 Foot Pounds of Energy

7.62 x 40 is yet another ripoff of J.D.Jones's .300 Whisper . Except that Wilson misses half of the origional concept.

The Whisper was invented to maximize the terminal ballistics of subsonic ( highly suppresable) load in an AR platform . Ie 220-250 bullets @ 1000ish fps , with violent tumbling. The fact that it could also aproxamate 7.62x39 supersonic ballistics was a happy byproduct.

The Wilson ctg trades off a slight increase in 125gr vels for a maxium capability of 150 gr bullets , at least in ARs. A bolt gun with a long throat would be less limited. But as long as you're going that route you could use any number of still larger cased factory or wildcat ctgs.

I've bought Remington factory ammo for the Blackout at a few local shops. Can the same be said of 7.62x40? While on paper, WC's may look slightly better, the tradeoff is that, frankly, Wilson's cartridge will always be a wildcat, whereas the Blackout has a good shot at being a mainstream offering. If you exclusively hand-load, that may not make much of a difference, except that hopefully, one day, I'll be able to get Blackout brass as Bass Pro; I know I won't be able to get 7.62x40 there.

Thats one of my concerns that i wont be able to get ammo for the 7.62x40. Is the 300 blackout ammo more common then the 7.62x40. Would you consider the 300 blackout as a good deer gun?

seen some folks using it for pig and deer

nasty wound channel for sure.... I would say it's suitable for deer sized game 200 yrds or less

For 300 blackout, use some 223 cases and a case trimmer....voila....300 blackout cases

krashmania June 20th, 2011 11:26 PM

Dang... that's just mean...

Jimbob2.0 June 20th, 2011 11:28 PM

Im intrigued as well, I would think it would come down in price as the projectiles are standard .308 and the cases are common.

Want to get my 7.6239 and my 5.45 set-ups done first before I get into a niche caliber but its on my radar.

Can't you do the same with 300 whisper? (or are these the same?)
