I’ve read that some .300 BLK rounds work better in magazines specifically made for .300 BLK, but does anyone know if 5.56 can work in .300 BLK specific magazines just as reliably as standard 5.56 magazines? Thank you

I have never had an issue running 300 BO in standard 5.56 mags. The 12.5 and 16" BCM I had both ran a several hundred rounds fine with them, I think some of the issue was people using Subs ( I ran Supers) that were on the heavy end ( 220g) and the OAL was the issue.
I am a sample size of ONE.... so take that for what its worth
Only difference in 300 BO specific mags would be the front rib that keeps the bullets in line is shorter, protrudes less into the mag body, to compensate for the fatter .308 bullets. Some may have heavier springs than .223 versions.

I apologize if I didn’t ask my question correctly. I just wanted to know if 5.56 rounds work in .300 BLK magazines, NOT if .300 BLK works in 5.56 magazines. For instance if only .300 BLK magazines were in stock for purchase and someone with only 5.56 ammo needed magazines.
I thought the question was stated very clearly.
I don't have a .300 BLK, so I can't provide an answer.
