[QUOTE="MontanaRifleman, post: 257527, member: 11717"] JE, I completely aggree with you. Maybe I should have used a more real world example. A lot of folks think that weight is a direct factor in bucking wind and my point was that it depends on how that weight is packaged. The only two factors plugged into the wind drift calcs are velocity and BC. I wanted to use two exagerated examples to illustrate that. Weight does play a role in BC and to what degree depends on shape and projectile surface. In a more real world case, a 7mm 180 gr VLD, with a BC of .659, fired @ 3250 fps will edge (No pun intended) out a 300 SMK fired @ 2850 fps, at 1000 yds by about 1" in drift and 45"of drop. Beyond the 1000 yd mark the SMK passes the VLD in bucking wind because of it's higher BC. So yeah, in most cases, with the bullets we shoot, the heaviers ones are better for bucking wind. In some cases a smaller bullet will out peform a larger one to some degree. Cheers :) [/QUOTE]
