300BLK in an SBR - practicality

[bzdog]

Is it worth it to go with 300 BLK if you don't intend to suppress it? I don't know if I want to get a can, but would like a handy SBR, just for fun. Maybe I should stick with 5.56, but may want to try the lighter loads in 300 BLK to avoid some noise, and muzzle blast for HD. Thoughts?

Yes, 300 BLK in an SBR with a good supersonic round like the Barnes 110 gr black tip makes an ideal PDW, IMO.
