yugo surplus,brass case,123gr? that's interesting Obiefox. that's one of the better,more accurate foreign surplus x39 out there. it's always functioned well in my AKs and usually gives a bit tighter groups than wolf too. i can't say i've ever found it underpowered but then it can range from 70's to 90's date manufactured if that makes a difference. thanks.
i keep reading about the #15 LP,i'll have to keep that in mind. this piece(LP) has a direct correlation between powder charge and roller efficiency,right? can you explain further? thanks.
