    Ballistic coefficient G1 and G7

    Re: Ballistic coefficient G1 and G7 Bryan, I agree to use the curve that fits best, but just looking at the nice outlines of the standard bullets is a bit misleading... I think you also have to take into account the diameter of the test bullet that originated the drag model. The "american"...

    Rifle Scopes h58 vs mil dot

    Re: h58 vs mil dot I know how to use them... just don't like them for the reasons above. When I heard that the military were buying some horus equiped scopes, I thought WTF??? Perhaps there is something for everyone.

    Rifle Scopes h58 vs mil dot

    Re: h58 vs mil dot To each his own... I don't like Horus reticles, too thin, busy and difficult to use in low light. What it gains in speed more than loses in complexity and confusion. Much prefer reticles with fewer, thicker, bolder lines. And even the old dots are easy to see in low light.

    Advanced Marksmanship Analyze This

    Re: Analyze This The comments by LL and CoryT are spot on, what more can I say... what a waste of time (again) trying to save something useful from SS posts. I won't repeat the mistake.

    Range Report BC/Performance Question: 155 Sc. Vs. 175 SMK?

    Re: BC/Performance Question: 155 Sc. Vs. 175 SMK? squarenut, the form factor concept is as old as BCs... The thing is, BOTH bullet shape and mass are important to retain velocity, and both are taken into account in the BC. The Higher BC bullet retains velocity better by definition. The...

    Rifle Scopes Origin of dots in mil dots

    Re: Origin of dots in mil dots The concept is hardly new. In topography most of the good optical levels and theodolites made in the last 60+ years have true miliradian based reticles to estimate distance. And most of them use etched glass since you don't have the constrains of a wire reticle...
