You guys that use them...do you put the knob in the palm/heel of the hand or do you use the web of the thumb to work the bolt? I've always used the palm/heel as my Dad taught me to shoot and he did most of his War fighting in the Pacific with a Mod 1917 Enfield.
Watch some top-end competitors who shoot on the clock, and you’ll see that most of them use an over-handed, crab-claw technique. I used to be a palm/heel guy (which I still like more for the “cool factor“), but for the last several years I have been using my thumb and forefinger in an over-handed technique as it is faster and more reliable, IMO. The palm/heel technique requires you to rotate the skeletal structure of the entire arm between raising the palm and pushing the heel, which takes more time and is more disruptive to the shooting position.
