    700fpe? That's 220 grains at 1200fps. Big bore for sure! Not .25 cal...'-)

    Yes its .457 but my real bigbore is 20mm made from Madsen autocannon barrel, we managed to achieve unofficial air rifle power record of 3150fpe, 2160grain lead projectile at 810fps. And no the weight is not a typo it was 140 grams of lead.

    Valves receivers, barrel work, chambering, stock inleting I do myself.

    Thanks.......good tips, but where in hell do you find 4130 in Europe? I assume you import it from the USA.

    Aircraft materials sellers usually stock 4130 tubing.

    Any of the HW rifles are excellent. The HW97 is a very nice rifle and would a excellent choice. It is a little on the heavy side, but if that doesn't bother you it's very accurate and one of the best quality production rifles made today. Flip a coin for what caliber you get. It's more a matter of preference, than one being better than the other. I prefer 22cal

    This is a follow up to this saga. I did want to buy the Kral Super Jumbo in 5.5, but several things got in the way of that. First, I could not find any dealer in Holland or Belgium that had the 2018 model nor did they know when they would get them. I tried calling distributors and the factory in Turkey.......no joy. I then started looking at regulators, barrels and control valves and the effort to put it all together quickly realizing that this could be a real bag of worms with a potentially dubious outcome. If one could put a price tag on the parts, effort and aggravation, it started to make sense to buy what you want in the first place and it would not be more expensive. So I elected to change my mind and buy an FX Crown. They are the cat's meow. Everything I was looking for and more assembled, finished and tuned at the factory in Sweden. It certainly was not cheap. I got one in 25 cal. This thing shoots dime groups at 50 meters out of the box. I'm very happy with it. I picked up a Discovery 4.5-18 scope for it with a Mil dot reticle and it works perfectly with very clear bright optical glass. Highly recommended. This is truly an amazing air rifle. I guess it's like the old proverb says, you get what you pay for. I will comment on my progress with this once I have some time with it under my belt.

    I'm currently using the JSB King 25 grain pellet. I'm not sure on the factory velocity, as I don't have my chronograph yet. When I do, I'll get back to you with the number. I have made no adjustments with anything. It is still factory set. The current setting of the regulator is 130 bar. I am estimating around 880 Ft/sec. The barrel is the new 60 cm long "X" barrel, where the rifling is rolled in externally. The bore is ultra smooth. The factory stated that the tune and barrel twist was optimized using the JSB King 25 grain pellet, which is advertised as having a .0360 BC.

    Would love to see a pic or video of that
    And would you elaborate on the design at all ie the valve

    Further follow up. I received my crono and measured at full hammer spring power, 940ft/sec with the regulator set for 120 bar. With the hammer spring set to minimum, the crono reads 640 ft/sec. This thing shoots nickel groups at 35 meters.........amazing. I'm reluctant to mess with the regulator. It works pretty good right from the factory.

    Did you wear it out already?
    It seems to be loosing accuracy

    Seriously though it sounds like a really nice set up you have.

    Sorry for the late reply.
    Well the valve is of balanced design, there is internal balancer piston and cylinder to help valve opening and closing.
