wondering about a 8.5" vs. 10.5" 300blk barrel?

pretty sold on a 300 blackout subsonic setup with 8.5" barrel.

really just will be a plinking toy, or perhaps a skunk set up, ha.

the only reason for the 10.5" barrel I see is to shoot supersonic 110gr type bullets?
or how much would I really lose with the 8.5 supersonic vs. 10.5? which is really a 2nd thought anyway.


Am I missing anything?

Thanks!

Just a WAG but on one of my pistols I loose around 200' per second going from a 14" barrel down to a 12" barrel.
