Throughout the forms on this site, you often read posts replete with photos showing "tight" 100 yard groups. Some of these are not what I call tight!
Most firearms are advertised to shoot better than one inch groups at 100 yards. Yet, looking at the published data in the American Hunter and/or the American Rifleman, you'd think anything under 2 inches was acceptable. Others may buy those lousy groups, but not me!
Any firearm with its salt, should be able to shoot 100 yard groups well under one inch with the right reloads. If it won't, perhaps you should try a different bullet and/or load? If all else fail, sell it and buy something that will.
Dead stock, .223 Remington, Model 700.
