I just thought this was really cool. Dark Horse Arms has come out with a Remington 700 in .308 Winchester that is integrally suppressed. And not only do they make the gun (and sell it for a cool $2,695), but they also produce some very interesting subsonic .308 rounds to go along with it. The three rounds I fired grouped very well. But really, how different is subsonic .308 and subsonic .300 BLK? . . .
The two calibers are damn near identical when subsonic. You have a .308 caliber projectile coming out of the gun and traveling at under 1,000 feet per second for each, which basically makes the ballistic trajectory identical for both cartridges. But the advantage with .308 is that you have more case to work with. Subsonic .300 BLK is very limited in terms of how much powder you can cram into the case before there’s no room left for the MASSIVE projectile. Does having more case space to use make it more consistent or better? How much powder are they actually using? I have questions.
I’m still not convinced that subsonic .308 is any different from or better than subsonic .300 BLK, so I’ve asked for a sample of their goods for testing. I’ll let you know how that turns out.
