Default Bullet BC question

Of these two bullets, which one would be less effected by the wind, the one with a higher BC, or the one that is heavier. The lighter one would be drive around a hundred fps faster and has a higher BC. I am of the understanding the one with the higher BC would be better?

Heavier is better than lighter.
Higher BC is better than lower BC.
You have two bullets, each of which in comparison, has only one of these characteristics.
Without running them through a calculator it would be difficult to say but I would lean toward the higher BC as well.

When BC and muzzle velocity are the same weight makes no difference on bullet drift.

Spot on, and lighter bullet can usually be pushed faster so it will show less wind drift even if the B.C. were equal.

Weight is only weight and doesnt really have much to do with aerodynamics. Areodynamics are based on design. Think pointed bullet vs blunt nose in simple terms

If speed is the same, the bullet with higher bc will drift less.

In your case, A lighter bullet with a higher bc with drift less than a heavier one with lower bc due to the gain in bc, you will also see a 2nd gain because lighter bullets shoot faster.

A lighter bullet with the same bc as a heavier bullet will drift the same amount if they are shot at the same speed
