[QUOTE="MontanaRifleman, post: 480383, member: 11717"] Welcome to LRH Tex Hunter!:) I think for close in in brush hunting it doesn't make much difference what your bullets BC is. My uncle in PA was the most successful PA deer hunter I ever knew and he used a .308 back in the day when when no one hardly ever heard of a bullet's BC. On the next subject of "manufacture's published BC's", you gotta take them with a real big grain of salt. First off, they are G1 BC's which are more suited for bullets that are not low drag boat tail type bullets. Next, you simply can not trust what most of the major bullet manufacturers are listing for BC's. Bryan Litz, who is Berger's chief ballistician, has done a lot of testing of many of the more popular low drag bullets. If you go to this Ballistic calc site, his BC's are factored into these bullets which you can select on a drop down menu. [url=http://www.jbmballistics.com/cgi-bin/jbmtraj-5.1.cgi]JBM - Calculations - Trajectory[/url] It looks a little intimidating at first, but you'll get used to it. The .270 WSM is a real sweet cartridge, but it's a barrel burner too (you might check out "nitiriding") That cal is not know for high BC bullets. 308 or 270 WSM... both will do the job for you on TX whitetail (hope your wife isn't reading this :rolleyes:), but the 308 will make a bigger hole. Because they all have their own criteria and agendas :) Hope that helps, Mark [/QUOTE]
