The bench versus offhand question has been around longer than Uncle Russ...
:shock:
Some good thoughts here. Still yet, I still feel strongly that nothing actually beats a good off-hand zero for hunting.
FWIW; I have often put my hand / fist against a tree for support when hunting, I have used a shooting stick with a leather strap that four fingers rest into, with the thumb supporting the rifle, and I have used crossed-sticks.
The closest thing to a bench in the field is cross sticks shooting prone, IMHO.
No matter what support or assist I use, I make double sure that the naked barrel of the rifle I'm shooting never touches anything.
As far as that "just right" placement of the stock on the assist, I've personally never been astute enough to notice much, if any, difference on where the stock was placed, but I do think I prefer something closer back toward the trigger guard. Others will swear by their own "sweet-spot" and try hard to place the assist in the exact same spot every time, and that is just as it should be.
I am not convinced that the location of "that exact spot" is really the answer, but I strongly believe that consistency in placing it in the same place will have some influence on the harmonics....especially if the assist is of something hard / rock solid, such as wood or metal.
Properly assembled cross-sticks have a leather thong that the stock fits on, vs sitting on hard wood, and a few of the old timers believe that is the real secret to their success.
