Wondering if its ok to run a 762-SDN-6 wet with subsonic .300 Blackout. Strictly 220 grain subsonic rounds. Just figured since the round itself is subsonic, it’s essentially the same as running a .45 ACP round through a Ti-Rant .45 wet, which is fine. I personally can’t see any reason why it would hurt the can, but its better safe than sorry so I will wait to see the feedback here.
For limiting liability, that is a no-brianer for AAC to say about all their rifle cans.
Furthermore, the OP specified SUBS ONLY. from the OFFICIAL 300 BLK site, here are the specifications on the subs OP is talking about:
• Sierra 220 MK loaded to 2.120 OAL (this length is optimal for reliable feeding from USGI magazines)
• Chamber pressure 21,100 psi.
That chamber pressurefrom SUBS is consistent with a PISTOL ROUND, not a rifle round. It isn’t even a hot pistol round: 9mm and 40S&W often run 35,000 PSI; +p 9mm runs around 38,500 PSI and +p+ even higher than that,yet pistol cans can take that muzzle pressure - from a shorter barrel.
and the suppressors we are talking about is fully welded with a stainless/inconel core and on longer barrels, it routinely handles 300 WM - so its not like gas volumn is going to overwhelm a can like this - certainly not with the 10 grains of powder used in SUBS.
Be careful, look for key holing and POI shifts. Your can shouldn’t blow up, but the baffle strike issue is still there. With that combo, take caution, as some of the turbulence change could hurt things and make headaches, K baffle cans can be worse with this than others.
