I recall seeing it posted somewhere regarding suppressing an AK or something, but wanted to pass this along. I bought 2 boxes of subsonic 7.62 x39 ammo to tinker with in my Yugo SKS with the gas valve shut off. I will test a couple to see IF they cycle, but got them for using with gas off. They are 150 gr JSP. $32 per box of 20. Expensive, but the only subsonice 7.62 x39 I could find anywhere. Name of the place is Detroit Ammo Co.
