How to tell if your gun fits you:

Are you experiencing pain or bruising in your face, shoulder or second finger of your trigger hand?

Practising your mount in a mirror — are you having to adjust to align your eye over the rib?

Closed eye gun mount — mount your gun on a ceiling corner and close your eyes as you do it. Open them immediately afterwards — are you having to correct your alignment?

Traditionally, point of impact was assessed by mounting and firing at a pattern board or sheet with a centre cross at 16 yards with a tight choke. Is the pattern where you want it to be?
