Well not too bad.

I shot it at an indoor range at 50M and while the light there is terrible (there is a big spotlight running right down the middle and the black circle disappears at 50M), the results werent that bad.

The photos show two groups and a six shot string. All are in the black at 50M and all had the right barrel printing to the right of the left barrel.

Dont pay too much attention to the height of the two groups in one of them, as I said the black circle was pretty hard to see at times.
