i am pritty new to air rifles and have just got a bsa r10 mk2 in 22 and not sure about the ranges what are expected from this gun. Also not to sure on what pellets to use.
just had main zerod and tested mate... up to 50 yds is realistic in terms of range... regarding the pellets, have a look at this :
.270 Blaser R8 Professional - Zeiss V8 1.8-14X50
12g Beretta 686 Silver Pigeon 1 Field O/U
12g Beretta A400 Xplor Action
