[QUOTE="MontanaRifleman, post: 812569, member: 11717"] Wind drift is effected by velocity and BC only. Nothing else. That said, when you change bullet size and shape you will usually affect the BC. The reason bigger bullets usually buck wind better is because they usually have higher BC's. Now if you compare the 7mm 180 VLD with a BC of .764 to the 35 cal 250 NP with a BC of .446, the 180 VLD is going to buck wind much better and all the more with a higher MV. But if you compare the 180 to the 300 gr OTM with a BC of .818, the 180 will have a slight edge in wind resistance past 1000 yds using your velocities, less than 1 MOA in a 10 mph wind. Flat trajectory is useful for point blank shooting to maybe 500 yds but is of no real consequence at longer ranges. In hunting, the advantage of the 338 cal 300 gr bullet is it's larger frontal and greater mass which will cause more destruction. You can answer your ballistic questions by playing with the ballistic calculators. And you can deduce that larger bullets will have a greater destructive potential. Bottom line, you can kill a game animal with a 7mm bullet or whatever, but the higher you climb the caliber ladder with like shape and construction bullets, the more effective the bullet will be and the more you improve your odds of a successful quick kill at longer ranges.
