    Rebuilding FX Royale 400

    Replace the valve seat with a new one. It comes with the o ring. I would replace the valve as well. There is a slight deformation somewhere that you can't see and you have the leak. The seal is not steel on steel. It's steel on Delrin.

    .22 CZ pellet barrel good with slugs?

    I have a cz barrel fitted to my FX ELITE. It shoots HN 217 / 25 gr and Knock Outs .216 great at about 34 foot-pounds. It also shoots the .217 / 23 gr. This group is at 118m with the 23 gr. The coin is about an inch.
