[QUOTE="Jon A, post: 65260, member: 319"] Yes, there will be variation, no two bullets will have [i]exactly[/i] the same BC if you take it out to enough decimal points, etc.... But I think it's important we not get lost in the minutia here. I've seen some bring up all these variables before as evidence that BC's are pure bunk, hokus pokus and aren't worth worrying about at all. A typical case of being afraid to identify a forest because he's afraid he won't be able to count every tree. Yes, there will be variation. A standard deviation is always a good thing to report with any testing. And different rifles, different twists, environmental conditions.... [i][b]But![/b][/i][b][/b] It is possible to judge the relative size of different forests without counting each tree in each forest with absolute certainty. I hate it when people see instrumented tests on BC's and say, "Yeah, well maybe in [i]your[/i] rifle the round noses don't beat the SST's but they might in mine.... Maybe under [i]your[/i] conditions a high SD sharply pointed bullet kills a light, low SD X-bullet...but in [i]my rifle[/i] they might not...they might be "magic!" Sorry, just ranting. That wasn't aimed at anybody in particular...just a direction I've seen arguements like this go before. Yes, BC's change, vary and are dynamic. But let's keep those variations in the proper perspective. [/QUOTE]
