[QUOTE="Mikecr, post: 865132, member: 1521"] Truths pass all tests. Your rule of thumb will fail tests as long as bullet makers/experimenters are adjusting center of gravity -vs- center of pressure. For instance, the current Miller rule of thumb results would not predict well with VLDs fired base first. McCoy's math certainly would, provided you're inclined to understand and use it. Still, McCoy's math holds flaws, and assumptions. So we currently hold no truths beyond carefully field validated. This is why I see current efforts to bell curve typical bullets as useful,, in a Greenhill sense. [/QUOTE]
