Re: Some 30 Cal BCs Tested
Mike, I just needed to know how the chronos read relative to each other. If one read 20 fps higher than the other and I didn't know it, that would skew the numbers one way or the other depending upon whether I put it in front or back. The relative comparison between bullets would still be valid, but much less absolutely accurate.
As it turned out, Oehlers are good. [img]/ubbthreads/images/graemlins/laugh.gif[/img] One averaged 4 fps slower reading the same bullet than the other (accounting for the 1 fps the bullet lost between the two). I only shot three to come up with that, but they were all single digit differences with a max of 7 fps and an average of 4. So I simply added 4 fps to the readings from that one when figuring the BC's to put them on a level playing field. Had the difference been bigger, neglecting to do this would have had a larger effect. But the only way to know for sure was to find the difference in the first place.
