I loaded some 7.62x39 subsonic rounds the other day (haven't in years) and forgot how much fun thay are to shoot. On par with the 300AAC for accuracy and performance.
Either 180 or 230 boolits at just over 1000fps showed superb 100 yard grouping with miserly loads of Red Dot. Nice to get over 1000 rounds from a pound of powder.
Anyone else shooting the "Russian Blackout"?
