Dial the top hat down to its lowest allowable point upon the stem, dont force it. Then as per the power wheel main indicator 2-4-6-8-10 fire some strings over the chrony. (1m away from bbl muzzle to chrony) That way you can see. Where you would like to be power level wise, you adjust the power wheel or you adjust your top hat. Start with that. The bbl is more than capable of sub 1" groups at 50yrds. Watch how you place your pellets into the bbl. Most flyers are caused by not feeding the pellet square to the rifling. or shooter error.

Thanks! Will dial the tophat down to more snug but not tight over the o ring I placed there. There is maybe 1mm of gap on both sides of the o ring. Your actually missing the point here. Throw that oring out and learn to understand the gun as it is. And the potential that the gun is designed. Adding more perameters will have you chasing numbers upon a chrony and you will get no where.And see where that takes me.

I know this gun has a ton of potential accuracy. Shooter error is number one issue so far I think. The scope height is massively high and I'm not used to it yet. Scope cant is a very vulnerable issue I must learn to account for with this gun as opposed to my other guns.
