I use a Dell Axim 50V , the NF program and a Kestrel 2500. I am very pleased. I practise often and feel very good about cold bore first shot hits. Yesterday it was a 12" rock at 841 yards. Longest shot on game to date was a small WT doe at 1137 yards with a 7 to 10 mph full value wind. I would say you are on the right track if you have the right rifle, scope and practise.
Good luck!
