[QUOTE="J E Custom, post: 419331, member: 2736"] Very good information Lou and Bryan !!!!! I had not thought about using the flat base bullets in over 50 years because I have all ways liked to shoot as far as my ability and equiptment would allow and the only choice back before computers was the boat tailed bullets. All of my trajectories tables/ drop charts had to be fired back then to recent times because listed BC were calculated differently from one bullet maker to the next and could not be trusted. But now that we have the computer it would be nice not to have to re zero for changes in altitude, temperature,humidity and so forth buy actually shooting a group under these conditions and have to modify your drop charts across the range to be used. What I see as the main benefit of good BCs for each bullet fired in a particular rifle is the ability to calculate a solution that will allow a shooter to correct for all known conditions and be able to predict bullet impact at any reasonable distance. I am not very computer literate but I do know that the better information you put in the better you get out of it. so that's why I would like accurate BCs not high numbers that don't work in anything well. What's the saying- Close only works with horse shoes and hand grenades. Please keep the debate going for the less informed members Like me. Thanks J E CUSTOM [/QUOTE]
