New member, getting back into air rifles.

I've just sent you a Private Message (PM) with my phone number.  Do call me if you need advice - there's a lot to discuss!  For example:

Finding your barrel's pellet preference, Artillery Hold, Follow Through, Leading your barrel, Wearing-in, Scope choice (preferred magnification, FFP/SFP, rating, focusing/parallax, etc), creating your ballistics chart, holdover/holdunder method, range-finders, wind effects, blah blah blah..... 

Lots of good stuff to learn over time!

For now, your scope requirements - look at Side Focus Hawke or Element models for starters.  They are all Air Rifle rated, good quality, great reticules, etc...  I personally shoot at x16 magnification so l'd suggest you look for models that include that level at least...  and always use Sportsmatch Rings to mount on your rifle.

Learning how to shoot Air Rifles well is a great journey!  Talk soon....
