[QUOTE="P7M13, post: 2612684, member: 94154"] [USER=104268]@entoptics[/USER], I've always appreciated your studies. How many rounds were fired to obtain the values for your results? I don't recall seeing an 'n' value. I ask because my desk measurements of a different brand of CNC produced monolithics shows a variation in the ogive from bullet to bullet. This would affect the ballistic coefficients, but in the range that I use this gun (300 yds), it doesn't matter to me. If I shot farther, barring my own accuracy limitations, I would expect the POI to open up considerably. I've never been curious enough to dig into ballistic equations and BCs at different velocities like what Sierra publishes. Have you ever considered doing the test with MVs which vary significantly, I.e full power vs reduced loads, and measured the difference in BC? [/QUOTE]
