Thinking of an SBR on an AR platform... Want something handy I can put my can on, and shoot stuff (paper, steel, varmints/pests, terrorists) maybe out to 100-150yds. My picks, so far, are 9mm, 223, and 300blk. I will be shooting this nearly 100% through the can, mostly supersonic.
Some pros and cons I've thought about...
9mm...I'm super invested in 9mm ammo, cheap to plink with, quietest (subs or supers), some say finicky to make run correctly, dedicated lower receiver, not as much power at 100yds as the other two
223...reasonably priced ammo, accurate (correct barrel twist for most bullets), more power than 9mm, not as efficient through short barrels, more gas blast to the shooter when using suppressor, more pressure on can bc of short barrel
300blk....ammo expensive compared to the other two above, efficient from short barrels, quieter than 223, able to shoot subsonic loads easier than 223, accuracy not as great (what i've read) due too fast twist barrels geared towards subs, more power than both above
I have no experience w/ the 300, only experienced 223 through carbines, and 9mm only through pistols.
I like the idea of the 9mm for the cheapness of the ammo, but seems like quite an expense for not much performance over a pistol. ??
Looking for others experiences/thoughts, that have been down this road. What did you choose? Why?
