Reticle drives me nutz

Regarding weight vs mass (keep in mind I wasn't part of the original argument on this). I've never weighed anything on the moon and most likely never will weigh anything on the moon, unless we suffer some weird turn of events in the near future.

So safe to say weight and mass are basically interchangeable as the gravity under which I'll ever be weighing anything isn't changing. Unless one want to consider the minute change periodically caused by the moons gravitational pull.

My biggest worry however is bouyancy, should I ever have the need to shoot a fish. There's no means to enter specific gravity in fluid into my ballistics calculator... so how do I know which elevation adjustment to make?

Allow for one LOP. Length of pike.

I really didn't want to "weigh" in on this conversation anymore but mass and weight are not interchangeable regardless of location.
Mass is constant and has magnitude only. Represented by kilograms (Kg).
Weight has magnitude and direction, represented by Newtons (N).
As I said earlier we all use these terms interchangeably albeit incorrectly
Shooting is not only a sport but a science.
The more accurately we apply it the better our results.
As to your shooting fish I think your primary concern would be the surface tension implications.

So how does this affect a 150 grain bullet? It weighs 150 grains on scale but it isn't weight, it's mass? So we should be talking about the mass of bullets? Even though we "weigh" them on a scale calibrated in grains?

You're right.
To be correct one should still refer to bullets in grains.
However a grain is a unit of mass and not weight.
As I stated earlier, most people use these terms interchangeably.
Oldest and easiest way to determine mass accurately is to use a balance scale.
Today we use spring/electronic scales.
These actually work by determining the weight of an object then internally converting it to mass.
This would be the calibration you refer to.
This is the value one sees on a scale.
I wasn't trying to be an instigator here.
I just didn't like everyone picking on some guy because he used the word "redicule".
 
So we don't weigh a bullet, we mass a bullet...?

I can see how we actually use the term weigh - correct or not.

Here's one for all you egg heads out there to ponder:

This is one application where weight is involved.

If one dropped a 175gr. bullet (no case etc.) from 1m and fired a 175gr. bullet from a rifle perfectly horizontal ( also @ 1m) at the exact same time, which bullet would hit the ground first?
Assume perfectly level terrain.

Are you doing this in a vacuum or is there air friction? In a vacuum theoretically they would hit the ground at the same time. The curvature of the earth may affect that...

In a vacuum the same time.
Fraction of a second later for the fired bullet do to air resistance.
Maybe curvature of the earth would factor in depending on distance.
Starting @1m height probably negligible.
I find this a most interesting study regarding ballistics.
