Chairgun Pro

Fellas,

 

am I missing something?

 

I have an Air Arms S410 Xtra FAC .22 using Bisley mags (21grain) - Power 31ft/lbs - scope height 2" - Zero'd at 50yds - mag 12

 

My rifle has adjustable power and to amuse myself (no other reason) I wondered if instead of using 1 mildot holdunder at say 30yds, I could decrease the power to keep a target on the crosshairs.

 

Common sense dictates that if you reduce the power, a pellet of this weight is going to drop earlier and thus lower the POI.

 

I have just used Chairgun to test out my theory and it shows that I would have even more holdunder, meaning that the POI has got higher....

 

Im confused

 

What am I missing

 

cheers

That's because you are probably still zeroed at 50 yards and a slower pellet will have a loopier trajectory meaning the barrel will have to be MORE inclined to get the pellet to the target, more incline = more holdover at mid range.

Yes I get it now....By reducing the power Im trying to achieve a zero at 30yds

 

Thanks
