Yep. That's what I meant. Never have bothered.
I know the .22Lr boys play with it but I've only seen mathematical theory that says its minute and never seen anything that's shown it to be of effect on air guns. More often than not there's been other possible errors such as cant or parallax or the anmo/gun that's pushed pellets in unexpected directions.
If we could shoot a wind tunnel where we push the pellet from zero to 6" of wind and see an angled line then I'd happily eat those words but I think the maths and other variables leave this in the don't worry camp.
I suppose we could always blind test it with barrels with different twist directions?
