[QUOTE="Dr. Tad Hussein Winslow, post: 1164155, member: 7123"] Well look at wind drift and drop at 300, 400, 500, 600, 800, etc. Primarily wind drift minimization is what you want, but also drop minimization. Most charts/software give you info with a 10 mph crosswind, for comparison purposes. The two key factors are bullet BC and bullet MV (ballistic coefficient and muzzle velocity) - the higher the better on both, but it's a tradeoff, and one can make up for the other to an extent. But the 6.5mm and 7mm bullet hit the 'sweet spot' for some reason on weight/BC ratio (and of course weight translates almost directly to MV). [/QUOTE]
