Interesting accidental discovery...

As would aiming the muzzle off in the required direction

guys you are all missing Jons point.

modern air rifles like the fx impact have interchangeable barrels.

that means you simply have to carry, lets say 5 different barrels each with a 5 degree change in crown.

you then choose the correct barrel for the conditions.

Most barrels these days are retained by grub screws - just rotate the barrel to give your preferred windage/elevation/droop

I've found that chamfering the head of the pellet works too, obviously you need to know how many turns your rifling makes (and in what direction) then you can load the pellet accordingly to buck the wind, or even ride it sideways around tree stumps for those obscured targets.

Regardless of what date it is - One of our more experienced club members last Thursday night seemed to have trouble zeroing his rifle which came with inter changeable barrels. Despite changing the breech seal in the quest for accuracy nothing seemed to improve the smooth twist accuracy. It was only later in the evening he made the discovery that .177 dont go to well in a .22 barrel regardless of the twist, seal etc. He wont live that one down for a while.
And I thought I was a Wally trying to zero a .22 Ace fitted with a .177 silencer (that was when Whisperer silencers were calibre specific.)

What you do is file a flat on the side of the pellet, dependant on the wind direction

You could also fit baffles to the muzzle, micrometrically adjustable... use them just like rudders... I just wonder, with all these amazing ideas, if the FT rule book will need to be re-written tomorrow morning...

That would be the variable muzzle angle barrel..

That explains a lot...
