The fist idea sounds good, I've done similar with the rimmy & PCP's.
The open palm (hand) was done sitting, just rested it on my open palm to see what would happen, boing.
Decided to definately take it to my local range.
In a few minutes I'll be able to see how much the pellet drops just shooting towards the bank backstop & watching the dirt kick up to give me a starter.
From finding out the aim point first I can get it over the farm & target shoot to see what happens.
Just hope it doesn't drop below my view at the the bottom of the scope sight picture.
