Any tips on how to shoot the Taipan Veteran cal 22 out to 100 yards?

The gun is not mine. But my friend told me he wants me to use his Taipan Long 22 in an upcoming BR competition. I would like to ask for tips from you guys. The ranges will range from 50 all the way to 100 yards. His gun is exceptionally a tack driver at 50, literally one holer for ten shots with JSB 18 grains. We have a video on youtube of shot groups out to 133 yards but I do not know how to post a video here.
