[QUOTE="Ken Howell, post: 20810, member: 23"] FWTW, a couple of echoes and cobwebs from the void in my gourd. If you were here, we could run some loads through the acoustic target and get a better grip on the de facto, field-derived BC. (I've heard industry people, asked how they get their BCs, say "We figure 'em as close as we can, then we look at what the competition claims." That has always filled me with about as much confidence in their figures as there's nourishment inside a ping-pong ball.) Also, the equations in your software may be the usual, traditional equations that have worked so well, for so long, because we small-arms riflemen never put 'em to the strain that your shooting puts on 'em. I asked the late Homer Powley what value there was in Art Pejsa's equations, and he said that the Pejsa equations are minutely more accurate than the traditional. I've heard users say that Pejsa's equations are noticeably more accurate out to 1,000 to 1,200 yards. I don't know anyone who's tested 'em farther out than that. I may have just wasted your time. I haven't checked any of this out, so I'm just throwing somebody else's cats into the burgoo. Strain the hair out for yourself. Hope I didn't ruin the pot. [/QUOTE]
