Ok I had her out at the range today and I have to say she shoots nicer then my #4 Enfield Sportster, and I don't say this lightly.
I was using 39 grain (and later 41grain) of IMR4064, with a 150 grain spritzer bullets.
The 39 grain were what could best be described as silky smooth, and the trajectories worked well with the Iron sights.
At 50 yards she is a tack driver...Once I figured out the sights, and noticed that the screw holding the barrel to the stock was loose, DOH!
At 100 yards she seems to group abit to the right, but all shots where within 1" to 1 1/2" to 2". (I call it Min' of Nazi)
Mind you I was shooting freehand for the 100yad mark, but got one bulls eye when I benched her which I could never manage with my #4 so it was prob' my wobbliness standing, and my near sightedness.
The 41 grain seemed more kick then effective, but sounded brutal hitting the
metal ram out at the 200 yard mark downrange which I managed to hit quite a few times.
I'll be making up a few 180 grain bullets to try next.
but for now I am very very impressed.
BTW the pushing on the bottom mag' plate towards the trigger worked! She popped open like magic...good thing too as she was a bit dirty in there.
