Someone still has to step up to RSO this one.  Gus has OIC, but no RSO. Same old people have been volunteering so I've been cutting back on my volunteering to force others to step up.  That and it's been crazy busy at work.

I hear you.  I just joined earlier this year and I've already RSO'ed twice for CR2. 

I spoke to Gus yesterday that if he was an RSO short and could have to cancel the range that I would be available, but something else came up for Sunday. 

I want to shoot as well, but I've told Phil many times that if I am free to shoot and he's an RSO short, that I would RSO so that the range could open.  I would then hope that others would offer the same just to keep things going. 

Right, and obvious.  Let's do a "what if"

You put your rifle in a vise, and align it parallel to the ground.  Then, using a delicate digital level, you incline it 5 degrees.  you fire a round.  A sophisticated tracking system records the flight of the projectile.  it notes, amongst all the other data it records, that between the distances of 400 and 500 yards, the bulled drops exactly 4", from a height of 6' to 5'8".

Now you increase the tilt by 1 degree, to 6 degrees above horizontal.  You fire again.  Obviously the point of impact changes at virtually every point along the flight path.  But between 400 and 500 yards, the bullet will still fall by about 4".  Not exactly, but pretty close.  Admittedly that drop is now happening at a different height, let's say from 7' to 6"8(ish)". 

Right?

So why doesn't that matter?

no.  if you tilt your rifle more up, you introduce more vertical velocity.  so the bullet will travel up slightly, before it starts its fall.  so not only is it shooting higher, but it's dropping later as it has to wait for gravity to overcome the initial velocity.
