A buddy of mine just purchased that same ML. He also bought the same bullet/pellet combo to try.
We took it to the range and it did okay with the pellets and SST's. It was doing around 2" - 2 1/2" groups at 100 yds.
I loaded it up with 100 grs of BH209,.45 cal- 260 gr Harvester PT Golds in black crushed ribbed sabots, ignited with CCI 209M primers. WOW,, that thing is a shooter. It was holding 1" - 1 1/4" groups.
The trigger on the V2 has to be one of the best factory ML triggers I have ever shot.
Like cayuga said, you have a very good rifle.
