Pk1,,,I can not, nor would I, argue with your statement as it is a truth...Quote:Every stress you put on the rifle, hand pressure on the stock, placement of the stock on the bag, touching the barrel, etc, changes in some degree the point of impact of the bullet. Putting the rifle in a machine rest may give you great groups but after sighting it in on the machine rest and shooting it with your hands and pushed against your shoulder will give you a different point of impact however slight....My only concern is obtaining the best group from test loads that I can achieve, with as little human factor involved...
Once I have achieved my best for the firearm/ammo combination, then it comes down to my shooting skills and as long as I know the equipment is performing at it's peak, any negative factors that show up are a result of my imperfection in shooting and lack of confidence in the rifle/ammo is not one of them...
