old roper, those F class numbers are very good indeed.
But I wasn't referring to such disciplines nor benchrest either when I commented: While to some this may seem exciting, but such groups from free recoiling rifles virtually untouched by humans today are no smaller than test groups with rifles normally fired from the shoulder shot around 1970. Those rifles back then were fired from machine rests, untouched by humans except for a finger on their triggers. Some 10-shot ones were well under an inch at 600.
