Shot my USMC 40X yesterday. Of course from the bench at 50 yards, The scope is a Lyman SuperTargetSpot 25X. For ammo, I was using SK Rifle Match. Fired a grand total of 20 shots. Five into targets of opportunity on the berm to warm up the barrel. Then three of these 10 Meter Air Rifle Targets. This was the best as the other two had a flier. So I guess there is some life left in the old girl yet.
