Hey there,Vera.Didn't anybody ever yell ya' that pretty girls that blast rabbits with pellet guns belong down south?Please refer to the manual.
Airguns tend to be EXTREMELY particular about what you put through them,even moreso than rimfire cartridges.If you experiment a little,you'll likely find a pellet that vastly outperforms other pellets in your rifle.
I've small game hunted with lotsa' the more common airguns over the years,and if you can tell me a make and model,I might be able to drop some advice.
For the most part,I've been unimpressed with the pointed,hollow point,and magnum pellets for hunting.I like whatever match grade pellet fires most accurately from a given rifle,bein as how with most airguns,you aint workin' with a heckuva' lot of kenetic energy to begin with,regaurdless of the pellet.Go with what's accurate,and put that little bit of energy right where it oughta' go.
One exception would be my Gamo 220 hunter,which for some reason,shoots RWS hollow points very well,and pushes 'em fast enough to open 'em up.
