    Barrel cleaning - pellet spiraling

    Nope !! Never use wd 40 mate, it will fook up your breach O-ring, personally, I only use .22 cleaning kit, dry. It's perfectly adapted to the .25 barrel size..

    Kral puncher Breaker 6.35, 110 yards shooting

    Yeah I'm pretty sure that ordering in Europe for the US is gonna cost a bit BUT this barrel is really worth the money spent... You can just email Rojal and ask them about the barrel !!!

    Kral puncher Breaker 6.35, 110 yards shooting

    Thanks !!! Yes this pup is really awesome for the price... Nice looking, easy to work on, well balanced, light, accurate... With a little bit of tuning, it becomes a real tac driver which can just keep up with those high end pcp's from big companies that cost 3 times the price of the Kral.. I'm...

    Technical question about regulators

    Hi all !! I was wondering... What really matters with the reg, is the pressure which is applied to each shot and not the volume of air right? I mean, the reg regulates the pressure and the combination Hammer / Hammer spring / valve sets the volume of air for each shot right ? So... With a 48...

So... I'll have...

    Velocity drop after barrel cleaning?

    Nope mate !! My s510 is regged and by now, it came back to normal velocities (890 - 895 fps).. After few tens of pellets through it, I think the lead lubed it and pellets don't have as much drag as a non lubed barrel. I guess what you Said bullfrog and Totally agree with you, as the rifling...

    Velocity drop after barrel cleaning?

    Yes.. Thought about it afterwards. As I only use micro fiber, I don't think it has any kind of importance, still, I don't like it. Just me being tired and dumb --"
