[QUOTE="Clark, post: 327671, member: 6600"] I can get <0.5" 5 shot groups at 100 yards with mixed range brass in .223. That is with the bullet + powder is 1500 times lighter than the scope + rifle. The rifle recoils .016" before bullet escapement. I get <1.5" 3 shot groups at 100 yards with new matched prepped brass in 7mmRemMag. That is with the bullet + powder is 300 times lighter than the scope + rifle. The rifle recoils .080" before bullet escapement. 1 moa error is .006" change in position of each end of the rifle about it's center. I moa error at 100y is typically from 20mph wind. 1 moa error is typically .004" of bullet tilt from bent brass neck from expander ball. What does it all mean? Brass brand effect is down in the noise compared to wind, rifle weight, ammo concentricity, bore cleanliness, barrel heat warp, etc. [/QUOTE]
