.300 blackout question.
Recently watched a video on youtube about caliber and damage in handgun rounds. Guys in the video were Federal and CCI (same company) development guys who work with the Federal and Military ammo development. A key take away was their statement of temporary wound cavity and effect on surrounding organs. Made it clear that bullet speed was more important than the caliber, ie., 2200fps was the magic number. The .300 in 220g is subsonic but only 1000+fps. Anybody got any info on the .300 220g in ballistic gels, etc? Thinking about a .300 blackout to keep in the house.

re: .300 blackout question.
As you said, .300 with 200+ gr bullet will be subsonic and will not give a wound cavity like a rifle round.
Think of it as a .30 caliber .45acp.

You can get bullets with 110gr bullets that are traveling ~2300fps.

Nothing wrong with this choice and whatever grain bullet you decide to shoot will absolutely do the trick.

There’s zero reason to shoot subsonic ammo unless you have a suppressor.

The 194g subsonic from Lehigh defense performs great for self defense (and some youtubers swear by it for hunting within 100yds but that’s a discussion in itself). They do ballistic gel testing with denim layers and a rack of ribs at 15:30 here LINK

re: .300 blackout question.
There is two kinds of damage from projectiles.
One is from the energy dumped into a substance. The other is physical damage caused by sharp edges and the projectile traveling through the medium. A typical high powered round, especially super sonic, actually does both. A subsonic round behaves more like a broad head. And, actually when heavier bullets are used can have amazing penetration capabilities.

IMO, the 300BO would not be my first choice for personal home defense. A short barrel 12ga shotgun loaded with OO buckshot, #4 buckshot, or #8 birdshot is devastating at short range. Most home invasion encounters will occur within 10-15 yds. ALWAYS know your backstop and what/who could be on the other side of the wall. A pump Shotgun and a pistol in the bedside table / nightstand is what many people use.

good video

another good video
