There is some merit to this. Most of the long range crowd is obsessed with shooting the highest BC bullet possible and they will ridicule you for shooting "light" 250 grain bullets. If you compare the actual ballistics you'll find that the higher BC bullet will always drift less in the wind. But the faster, lighter bullet will shoot flatter and carry plenty of velocity out to fairly long ranges. A flat trajectory is often overlooked as a benefit to using lighter bullets since its assumed your range will be precisely known. That philosophy works great for steel targets but animals move. I have personally had more issues with bad shots due to ranging errors than wind reading errors. Another advantage to the lighter bullets, especially in a hunting-weight 338, is reduced recoil. Those 300s will boot you pretty good even with a 12 lb rifle and a decent brake. 250s are much more pleasant to shoot.I’m reading a lot on 250’s shooting flatter with less wind carry until you get WAY out there.
