    Abda I have not really tried to rapid fire the TX and to be honest would never need to. It makes sense that rapid firing it might lead to a slight reduction in performance, the spring and seals are going to get very warm, if not hot and as things get hot expansion occurs and gaps might get slightly larger. Plus the characteristics of the spring might be altered slightly, as I am not an engineer I could not say for sure but I d have a limited amount of experience from working in the auto trade and nothing you said really surprises me, in fact I would be surprised if it had not happened.
    As far as the big bore and it not shooting on the low setting with a full tank that also makes sense, a matter of physics my friend, on low power the hammer has not got enough energy behind it to open the valve with 3000 psi holding it closed. You would think the manufactures would have made the gun with a dual power valve that would somehow reduce the air pressure holding the valve closed when used on the lower power setting. Maybe the gun was intended to be used on full power until it reached a certain air pressure and then to be used on low power to extend the time the hunter could use the gun, but one would think this would have been made clear in the users manual. Anyway my friend, you know the answer, use it on full power all the time, lol All the best, JC

    Yea, but it was a darn good exaple, right? Did the trick.

    And yea, I pretty much just use high until I get to point. Still playing with it to see if the combinations are worth it with the power posistions.

    Not been out shooting lately. Tired I am. Slow mo, ugh . . . can't . . . . hardly . . . . . move . . . .stuck in molassas. Crying or Very sad

    I use Hawke Chair Gun Pro. Got it for free---I think because I have a Hawke Sidwinder, not for sure on that one. I can shoot you a link if you want then you could check it out regardless. You want I should?

    And you do get the plus and minus signs in the upper right hand corner now, don't you?

    Thanks, I couldn't remember one way or the other and didn't want to take the time to look it up.

    Great program and actually helped me visualize things I couldn't seem to grasp through written word.
