Hey there Dave, thanks for taking the time to share that wealth of information, best regards to you

Very good Dave....when I first started in airguns 2008 I did same thing except i never applied the PBR or OPBZ factors....seeing your video I now have an application for them...lol I hunt so I did have need for drift (wind) and always used 5 mph 90 degrees as factors...another card I used was for incline shots ( 20 deg-_ 45 degrees)

Nice work Dave. Been along time since I've done this.

scope height is more critical for close distance and BC is critical for long distances

AMERICAN FT is it coming to a range near you???? out to 100yards

Strelok Pro better and worth the money. Chair gun only has Hawk reticles and generic ones. Strelok has just about every one on the planet
