Had a go with one of these at the Monmouth Shoot yesterday and got owned!
a) I volunteered to go first. If I'd have gone second I'd have done what you did and put the safety of my head above getting a good sight picture!
b) I did question the eye relief but Martin assured me it would be fine... with a smirk on his face
Case next to a .30-06
Come on GYR... show us yours!
