I grew up on a family farm ,and there were various things that pissed my father off ,one was not riding a horse properly ,holding the reins correctly etc, he only had the patience to teach one of us everything ,which was my older brother who was five years older than me ,the rest of us were expected just to know, or else we got an angry earful .
Another thing he hated seeing ,from being in the National Service and from his own father ,was not using your thumb and fore finger to work a bolt rifle, so i quickly learnt .When i watch You Tube videos of people shooting it just makes me cringe ,when you see shooters using the palm of their hand, their entire hand ,five fingers [not even consistently ] to operate a bolt action ,[especially U.S shooters who are acknowledged as a Nation of rifleman ],even some U.S Army snipers ,who are supposed to be Professionals displaying Bubba bolt manipulation ,i dont know why it isnt considered important ,from the point of safety ,efficiency and professionalism .
