m just wondering what the opinion of the board will be.
It might be lower it might be higher it might be left it might be right. It will be fairly close and you might be able to live with not moving it but you will have to check.
Also 150 crklt doing 3200+fps completely destroy the front ends of deer.

Correct... In a vacuum. You'll attempt to address that below...

The only thing that would reduce an object's time of fall (acceleration of fall) is air resistance (drag). So, if you drop two objects from a bridge with the same dimensions (say a 12 inch sphere), one weighs 1 lb., and the other weighs 100 lbs, they hit the ground at the same exact time.
150g and 180g projectiles don't have the same dimensions.
For the record, I'm only arguing for the sake of arguing.
My answer to the OP, inside of 150 yards, send it.

Not exactly. Gravitational force has nothing to do with being in a vacuum. However, I think what you are trying to say is that if a heavier projectile were longer, it would have more horizontal cross sectional surface area than a shorter projectile and therefore more air resistance when dropped. This is true but also likely negligible in the equation during the milliseconds (or seconds if shooting a mile) of flight time.
How about this scenario…… if you shoot a bullet from a perfectly horizontal gun along flat ground, and you drop a bullet at the same time, they will hit the ground at the exact same moment, just not at the same place.
That’s why long range shooters attempt to reach the highest velocity possible while still maintaining accuracy. If your bullet reaches the target faster, it has less time to be affected by wind.

You forgot to account for the curvature of the earth as well as downdrafts from birds and updrafts from thermals.

Well you clearly havent been paying attention. Of course a simple question about changing bullet weights would result in a physics 2001 refresher.
To answer the OP, you need to shoot it to verify. Might be exact same zero or close enough. Some rifles shoot basically everything to same point of impact. Some are ultra picky and wont put two different loads in the same zip code. You need to check it and see.
