    FX I can't tune this… Impact M4 extended .22… with 18.13 grain pellets…

    While waiting for the 600 mm non-Heavy barrel to arrive, I tried shooting with 25 grain pellets at 950–960 fps. I raised the regulator to 105 bar and gradually set the hammer spring to 2. After reaching a plateau velocity of 990–1000 fps, I lowered the hammer until 960 and closed the VA until it...

    FX I can't tune this… Impact M4 extended .22… with 18.13 grain pellets…

    Yes, i bought it in "extended" version. I think hammer is too strong...Otherwise, although the barrel is "superior heavy" the accuracy is good with pellets

    FX I can't tune this… Impact M4 extended .22… with 18.13 grain pellets…

    I might know the answer to the problem. I bought the rifle a year ago, and those who understood already warned me about its power. The beast is the Impact M4 extended (800 mm) with a superior heavy barrel. I know it's designed for slugs, but I don't know what it is about the JSB 18.13 grain...

    Daystate Alphawolf: Leak from regulator knob when shooting. Is this normal?

    Well yes, the air is coming from the shroud. False alarm. The accuracy trouble is due to clamp barrel, i think...

    Daystate Alphawolf: Leak from regulator knob when shooting. Is this normal?

    I'll check it later. Maybe it's the shroud.

    Daystate Alphawolf: Leak from regulator knob when shooting. Is this normal?

    Hello everyone. I think I have a problem with the regulator on my Alphawolf. For the past few days, I’ve noticed worse consistency and accuracy when shooting. I did the tissue test to check if there was an air leak at the transfer port, but it was actually my daughter who noticed, when sitting...

    Daystate What type of connectors does Daystate use for the Alpha Wolf barrel-chronograph connection?

    Hello everyone. One month ago, I bought the barrel tensioner for the Alpha Wolf from Daystate. To my surprise, when I connected it, the chronograph was not recognized. The original one works perfectly, so something must be wrong with the cable on this accessory—maybe a bad connection, poor...

    Other Canting, harmonics, or shooter error?

    I’m shooting at 43 meters on a -5° slope. Target: 20x20 cm card with 5 bullseyes (2 bottom, 2 top, 1 center).

    RAW Rapid air leak in best fittings reg tester for non x tm1000 regulator

    Let me ask you a question aside from the leak you have: doesn’t the original Theoben regulator require the V-shaped piece slid over it for filling the bottle and the pressure gauge of it? If so, there will be an air leak if you don’t use it on the tester, right?

    RAW Rapid Huma regulator RAW HM1000X question

    First of all, thank you very much for the clarifications. The original regulator is in perfect condition, but due to the impossibility of measuring the regulator pressure, I ordered one from Huma (getting an original one in Europe is almost impossible) so that a custom tester could be made for...

    RAW Rapid Huma regulator RAW HM1000X question

    Hi everyone. I’ve asked this question in another post, but with no success and no replies so far. Let’s see if someone here can help me. I’ve bought the Huma regulator for the RAW HM1000X, set at 143 bar. It only comes with a brass disk that screws into the area where the bottle attaches. But it...

    Tuning RAW HM1000X and Huma 1174 adjustable regulator problems

    Hi everyone. A few weeks ago I bought the Huma regulator for the RAW HM1000X. Today (yes, today...:rolleyes::rolleyes:) I realized that the Huma regulator only comes with the brass seal for threading... Is it supposed not to need a piston or Belleville washers? Or do I need to get those...

    Some BR questions and troubles i can´t solve it

    I have to say in my defense that I love benchrest, but I don’t consider myself even remotely good enough to compete, nor do I intend to. In Spain, there's little interest in this discipline. Shooting in this style and the 'need' to make good groupings is more a matter of mental hygiene — ending...
