Thread: .308 vs .300blk

300blk is a great cal, but is no quieter than 308 subsonic
I used a 308 up to getting a 300blk and they are functionally the same with the 308 bieng easier to feed as its long and just more stable
no contest if you have an AR as 308 isnt gunna fit so if thats the platform you want to run
300blk wont really do 300m well as its running out of puff a bit by then

anything starting with a .4 is going to be significantly louder.
