Thread: 7.62x39 or 300blk

My favorite rifle is a Brno ZKK 601 re-barreled in 7.62x39. I reload for it as the chamber is too tight for cheap steel cased ammo which has a tendency to be hard to extract. Other than that I have found it takes anything inside 200M.
I haven't owned a 300Blk but I am sure it would be very similar. If I was to put a new barrel on though I would certainly go 6.5 Grendel which in my opinion is a nice step up with better ballistics.
