So how's it done, then?

I owned an HW45 a while back and couldn't hit a barn door with it. Well, that's not strictly true - I did get good enough to tell that the accuracy was definitely there, but I never really got confident at shooting it.

I've just bought another and have the same problem: This one's dual power. On the half power setting I can get semi-decent groups, but at full power it's all over the place.

It's not the gun, it's definitely me!

So what's the technique?
