[QUOTE="Bart B, post: 494730, member: 5302"] I don't thing any of us humans can hold a rifle with its butt hard against a shoulder, stock fore end atop something along with the way most of us pull the trigger can shoot as small a group as the same rifle (and ammo) will produce when fired from a free recoil system untouched (or virtually so) by humans. One free recoil system's like benchrest rifles use; the rest atop bags or rests, slide in free recoil such that their point of aim's not disturbed by recoil while the bullet goes down the barrel. The only human thing touching them is a finger on their 2-ounce trigger. The other a machine rest with the rifle clamped in a cradle riding in three V blocks for perfect repeatability. Very heavy recoiling rifles can accurately be fired from such devices. With good ammo, barrels and assembly/fit techniques, old Model 70 Winchester actions bedded in wood stocks have shot groups from such devices smaller than current bench rest records. As long as we choose to hold onto the rifle and shoot it, the best position seems to be shooting from prone. Slung up correctly with the fore end resting on something and the stock toe also resting on something, this seems to produce the best accuracy when firing rifles from the shoulder. One other issue; if you don't shoot at least 20 shots per test group, the probability of the group size reflecting what the rifle will do at least 80% of the time is doubtful. One 20-shot group's worth 4 times as much as four 5-shot groups. And the largets group one shoots is the best representation of what one can count on all the time. Even benchrest rifles rarely better the record group they hold; all the rest are larger, oft times much larger. [/QUOTE]
