300 Blackout vs 223: Rifle Caliber Comparison by Ammo.com

Since My medical discharge I have not fired a single .223/5.56 NATO round. I don't own anything built around the AR-15 platform. Didn't care for them while I was active either. I've been a fan of 30 cal as long as I can remember. I do have a long gun based on the AR-10 platform, and several other non-semi 30 cal rifles. I'd like to do a side-by-side with my SR-10 and one of these 15s chambered in 300Blk. After all the 15 is a lighter platform. This is purely My Point of View.
