Von Gruff i am in agreement with Doc on this subject ,as my first .416 rigby was just a rechambered Brno which had the swivel stud mounted on the forend, and when i shot a lion in tanzania with it i didnt give a sh-t what the lion was up to after the 1st shot, as the quick detachable sling swivel had bent itself so much on the 1st finger of my left hand it had fallen out of the mount and i was more interested to see if my finger was still there , let alone in one piece than what the lion was up to!! that was the last time i had a sling on a hunting rifle (or the stud mount not on the barrel) as i find them a pain any way. and before anyone tells me i wasnt in control of the rifle it wasnt the 1st time i had shot it but it was the only time that happened, but also it depends on what posture your body is in when you take the shot as your hold can be different. all i know is i wouldnt want to have to think about where my hand was just in case it had slid too far forward due to me being in the less than normal stance. i can tell you it took ones mind off the circumstances at hand, which when people are telling you to shoot again and you are jumping around holding your hand and telling them to f--k off probably isnt the best.....
