    Stopper:-

    You can use pellet BC in ballistic software programs like Chairgun but the proof of the pudding is in the eating. Dont be disappointed when your actual shooting does not tie up with your nicely printed ballistic trajectory.

    If you come early enough you can do range finding and set your scope for different distances on the shooting range before the shoot. The shooting in targets are normally 5 meters apart starting at 10 up to 50 m. It is easy to zero/setup your scope for the different distances. If you battle with it, there will be plenty guys to help you with it.

    Bring pen and paper and jot down you zero setting for the various distances and use this at the actual shoot to determine your scope settings. You can then also see the different systems the shooters use to utilise these drop charts/settings.

    Hope to see you at the shoot on Saturday.

    I found chairgun pretty accurate regarding the H&N Baracudas, I plotted my actual range results on the program and through that worked out my guns fpe,when the result came in it was low compared to what i thought it should be, but after putting my gun over a chrono the program was right,spot on! I havnt tested it with other pellets. Really nice to play with
