We used 3 shooters with mutiple (at least 3 shots each. We weren't using a bench but were each using a rifle style hold, not mounting and shooting. All shots were with the same Winchester factory loads (that I always use) of the same lot.
We all shot low. Since I am 6'5" and have a 37" sleeve so I tried it with and without a slip on pad. Result was the same as I would expect.
