Thanks for the detailed reply Brian, lots to think about. I don't have a high mag scope at the moment so will pick up a cheap one so i can try it out & see how i get on. I have been looking over videos on youtube of the shoots recently.
I am at the Air Arms shoot this sunday so won't be able to make the Kent open unfortunatly Dave.
In life you should not persue goals that are easily achieved, develop an instinct for what can be only just achieved through your greatest efforts.
