From another thread, regarding accuracy at 100 yds...
The biggest factor at 100 yds. is wind/air turbulence.
You’re at the mercy of the environment with slow, light pellets vs 3000fps bullets.
Sometimes it’s nearly impossible to tell if an errant 100yd. shot was my fault, the pellets fault or the environment.
Unless of course you shoot sorted, sized pellets indoors with the HVAC turned off.

Use a copy of Hawke Chairgun Pro with your pellet of choice, at the velocity you shoot at. Then see where your strike is with a 2 mph wind (set wind direction at 270 degrees), and then run it with a 7 mph wind and look at the difference in strike (left to right).
Exactly.
The difference between 25yds and 100yds w/ a 2mph wind is about 2″. And that’s only 2mph.
Now, with a 7mph wind (only 5mph extra breeze) the difference is nearly 9″!
And we’re not even talking about thermals; hot concrete ground up range vs grass or dirt down range will cause all kind of crazy thermals that reek havoc on a light pellet, up, down sideways – measured in inches at 100yds.
Just have fun at 100 yds., don’t judge an airgun's accuracy at this range.
(Edit: the same applied to a 55gr .223 at ~3000fps at 100yds. 5mph wind change, is only ~3/4″!)
