A year or so ago I bought an Interarms Mark X MZ bolt action rifle in 7.62X39 at the Puyallup WAC show. Its an older well used rifle but I'm thinking about all that cheap ammo to shoot. The stock had suffered some trauma and been repaired and it had an old K4 Weaver scope. I took it to the local shoot dump when I got home and couldn"t get a group a 50 yards. Oh well put in the basement. Took it out today and took the action out of the stock and didn't see any obvious problems. Some one had tried to glass bed it and I figured I might have some work to do but put it back together and while torqueing the screws there was a "click" sound. Pulled it out of the stock and didn't see anything wrong so put back together figureing it seated. Went to the shoot dump couple miles from home and set up target at about 30 yds. Shooting off a rolled jacket got 4 shot 1 1/2" group couple inches high dead center. Moved target to about 100 yds and shots were about 6" high. Adjusted old scope and got 2 shots high and 2 shots where I adjusted for. Tried 4 more shots and got a nice 1 3/4" group. I figure the 30+ yr old Weaver was sticking on adjustments and settled in after a few shot. This was with Russian steel cased ammo marked 3 94 on the case head. I can't wait to try some good hunting ammo. Has anyone worked with a bolt action 7.62X39 and what can be expected with good ammo. Plinking offhand out to 100 yds was a lot of fun with the cheap Russian ammo. I figure this is a good beater rifle for the west end peninsula drives and target of opportunity.
