Well on the program I'm using the drift in a 10 mph crosswind at 1000 ft elev in 30 degree temps is as follows.

The 180 gr launched at 3070 is 46.9" @ 800, 61.8" @ 900, and 78.6" @ 1K.

The 200 gr launched at 2970 is 40.5" @ 800, 53.5" @ 900, and 68.2" @ 1k.

Would be interested in seeing the results from other programs for comparison purposes.

Ignorance can be treated with education, sadly there is no cure for stupidity.

Yes I did not have the exact data about wind drift but the idea behind the question was to point out that high BC bullets are not just intended for achieving a flatter trajectory but less wind drift.- At known distances ( i.e. lasered) drop can be easily corrected... wind drift is much harder to assess.

For that reason, even though the 180 ACCB may shoot flatter at some distances, the higher BC of the 200 ACCB will give it an advantadge if velocity is not too low.

Thanks for the info. I think I will jump up to the 200's beacause of the decreased wind drift. I was mainly focused on the drop and penetration aspects but having less wind drift would be a big plus. I have been lucky up to this point and have not had to deal with much wind but I know those days will come.

Don't get me wrong I like heavy bullets.. I built a 338 Laupa around the 325 Grain Wildcat bullet and I am going to build a 300 Ultra around the Widcat 265 grainer
range it,check the wind, dial in correction, aim and only one shot
