FNG / New Forum Member today, registering just after my first range session with my new SA SAINT .300 Blackout pistol. Supersonic .300 Blackout ammunition replicates the ballistics of 7.62x39mm, used by classic AK pattern rifles, but with cartridge dimensions designed with the AR-15 magazine in mind by JasonM Mon Feb 06, 2012 8:09 pm, Post Given equal penetration a larger bullet will damage more tissue and cause more bleeding. https://www.youtube.com/watch?v=Dh7Apv8YyVM?t=5m39s.

MjQxYzgwMWFlN2IyYmNlZWI5N2JjZGQ0ZGU1MzQyZmI5MWMwODk1ZjUxYmMw Just keep in mind, if you are wanting .308 performance.buy a .308. nope. .300 Blackout subsonic is not ideal for medium to long range hunting, as the velocity and kinesthetic shock is greatly lowered from the supersonic. I've been tying to keep an eye on 300BLK supersonic development, for me what comes out of supersonic in the next months will tip the scales on whether I go 308Win or 300BLK on my next purchase. A bullet traveling at higher speed means more energy that can be transferred to the target upon impact, more effective range, more tolerance to drop and wind drift. Thats another debate for others to work through in other articles, but its my story and Im sticking to it. ZDUxNWQzNTY2ZTJiNjVhN2RiMzgwOWMxNWVlNDlhN2UyYzM3MTRiOGEzN2Zh From heavy subsonic loads to supersonic rounds, both with and without the silencer attached; we experienced no malfunctions of any kind". [emailprotected], Reduced risk of over penetration from a pass through projectile. You seem to have found a sweet setup in this article that does not have any feed issues. (Clearly, supersonic Blackout beats it soundly.). ago. There is Barnes RRLP in 300 BLK, though it may end up as LE/Mil only. For anything larger, or at distance, we would recommend going supersonic. I got into .300 BLK because it excels in short rifles and has subsonic ammo for suppressor use. I really like the FAL adjustable gas system. I have an SBR as well in 300BLK which is more fun but when traveling out of state it's easier to just take my 16". And, yes, a supersonic blackout can have all the same extra-pressure-induced operation symptoms as a 5.56. MmI2MDAzY2VkZmQ4MzZiZmU1OWQzZjU2ZDIxMmM4OTBjMGM2NDQ3YWEzNTUz OTdmMTQ0NThiYmQ1YTBkNDc2NGIwN2E1NzFiZTVjMDVlMjJhZTViNTU0YmI5 Final one was with a 5.56 Ruger American Ranch Rifle.

The 7.62x39mm is another that can be made to be a great subsonic cartridge (but most factory ammo is supersonic). It cracks me up, that the 320 pound, crisco leaking computer chair army speaks of subjects that they "read" on the internet. The farther down the barrel the gas port is located, the lower the pressure will be by the time the bullet passes the port and the gas enters the port. Most factory .300 Blackout subsonic loads are a little more powerful than a routine .45 ACP handgun loading, if we're going on (the admittedly incomplete) calculated energy figures. Y2ZiMWUwMjljYjc2NjMyZDRjOTA0ZTkxMzk2MGEzMWVmMjFmYWVlOTdjZjFm NmYzMzU2MjU0YmYzZjg4NDg1MTU4MWE0NDc4ZWUyODcyZTAwNjVhMmQxMjcy NjI2MDFhZjNkMzY1NTA2MTQxNDNlYjJmMDNhNTQwOWM1ODc5MGRhZWY4Njlk Oh, my only hog of this year so far was with a 16" Noveske 300BLK.

But! 300 blackout is very much a do-it-all round, but if you're not gonna be shooting suppressed and the shorter barrel length doesn't matter go 556. . by 300Blk Fri May 27, 2011 10:17 am, Powered by phpBB Forum Software phpBB Limited. Done like that, the relatively tiny amount of fast-burning propellant behind that honking .30-caliber bullet gets put to work effectively because the pressure at the gas port is higher. One trick to get reliable subsonic function in a gun thats been built around more ideal supersonic function is lightening up the back end of the system. ZmU3NWNhNWM4YjFjYWNjMTMwNTE4MTRlZjNjNzhiNDE2MTgwMzE3NmFhZmUz Always (always) keep in mind that were operating in a world of fractional milliseconds defining too much and not enough, and hotter and cooler..

In terms of ballistics and terminal performance, supersonic is where 300 BLK really shines, especially in SBRs, and especially compared to 5.56 for short to mid-range use. That really all has to do with bullet design/bullet engineering. You dont have an issue with your 300blk if it wont run subsonic ammo UNSUPPRESSED! The Mission of Cheaper Than Dirt! cursor: pointer; On the other hand, supersonic offerings, when combined with suppression, will still conceal ones position and affords longer range lethality due to flatter shooting, lower weight bullets.

Btw: Supersonic ammo is also a really bad idea because of the VERY loud report and large muzzle flash. Post I had it 6 months before I got the silencer and put 500-700 rounds through it.. Gain a deep knowledge of ballistic science and access our improved ballistic calculator. - And the Mode 3 screw allows a varied amount to gas to be used in cycling, and the correct amount of gas (and the setting of the AGB) is dependent on correct cycling, using the procedure outlined on page 35? The price of subsonic 300 BLK now averages $1.15 - $2.85 per round (Consider this cost if you plan on using subsonic 300 BLK to shoot follow up shots rapidly on target). Most factory .300 Blackout subsonic loads are a little more powerful than a routine .45 ACP handgun loading, if were going on (the admittedly incomplete) calculated energy figures. by 300Blk Fri May 27, 2011 7:25 am, Post Id suggest running a standard USGI-spec buffer and plain old standard variety carbine-length spring for subsonic. No big surprise guys but Short barrel+weak ammo+ no backpressure=shit reliability ps. Despite larger bullet expansion size the temporary and permanent wound cavities of expanding subsonics are typically much smaller than expanding supersonics. } by 300Blk Mon Feb 06, 2012 9:00 pm, Post if running nothing special and you just want a 30 bore get a PSA 7.62 x 39 upper kit. A suppressed supersonic load will have a lot more gas coming back into the action compared to an unsuppressed subsonic load (these two examples are the extremes).

These are not as common now as they once were, but an AR-15 carrier doesnt have as long of a full-profile section on its body as does the USGI-standard M16-format carrier (which is far and away the most common now). If you don't have any experience with a suppressor I recommend you do your homework on the different models as cost doesn't always mean best sound suppression or quality.

If anything, its the heavier bullets that are more likely to keep going. If you do plan on shooting suppressed or aiming at targets within short distances then proceed with the 300 blackout platform. I enjoy them just as much as the short ones. Maybe a greater margin of error for nicking a vital organ as a result of larger bullet expansion. Instead of just yelling at the clouds, I thought we could bring in a few experts in the field of ammunition development and ask them for their thoughts on the matter.
