[QUOTE="ken snyder, post: 483208, member: 26019"] Lets argue is too much to resist! let me unqualify myself. My lonest deer shot is a little over 800yds. I target shoot more than twice that. I have no way to scientifically measure a b.c. in the wind other than averages in drop and deflection. I dont know how far it takes for a particular bullet to go to sleep but have seen that the same bullet in different rifles may be as much as 50yds. difference. When I started seating just ahead of the major diameter of the ogive I noticed that the oal changed by as much as .003 and more. barrel diameters vary and every rifle will swage its bullet different ( change its overall shape a little) Rifle engraving also changes the bullet because it will not start at the same diameter on all bullets. G7 or G anything is not a perfect match to anything other than the standard. When I add this up I wonder how any 2 rifles could possibly shoot a bullet with the same b.c. because it doesn't matter what goes in the chamber compared to what comes out the muzzle. At yardages as boring as 1000yds. I dont think the differences amount to didly squat on a pie plate size kill zone but makes a large difference at 1500yds. between rifles. for me at about 1200 yds. I start using a lot of fudge factor. I myself am not competent enough to harvest animals at 1500yds. but feel very comfortable shooting targets. I know there are lots of people who put enough time money and effort to do so, perhaps well beyond 1500yds. [/QUOTE]
