Looking for help with lower power .223 loads

I think Kazoo played with low power .223 and the results where less than spectacular... Is your can 223 or 30 cal? .30 cal begs to have some blackout ran through it

Unfortunately 223. I kick myself a little but for not just getting a .30 can.

guess I'll have to get another one...such a shame.

Once you hit supersonic speeds, will a projectile of that size/mass make that much of a difference in sound intensity within that range? I don't know the science behind it, so I am just asking.

ETA: SS crack of .223 projo at threshhold of sub/super vs same at 3000-3200FPS ?
