The point at which all this happens has plauged my brain for quite some time. Is there a "rule of thumb" or special mathmatical equation that's probably over my head that one can use to find this point? Or do you just have to burn rounds to find out for yourself with each combination?
Is faster better?

I don't think that you will be displeased with a Berger or eld-m 180 grains & up in that cartridge. With a 26" barrel, I think that you may be able to push a 180 to 3050 fps with that cartridge and a 190 to around 2940. It's highly likely you will find an accuracy node around 3050 fps. There should be one or possibly two accuracy nodes between 2800 to 2940 fps with the 190. Of course the higher B.C. bullet at any of those velocities I mentioned is going to resist wind better than a lower bc bullet. Any way you slice it, a 190, 195 or 180 pushed to those velocities is going to be impressive granted that you have good accuracy along with those velocities. They may all shoot great for you but more than likely, the rifle will prefer one of these bullets over the others even if there's just a small difference in group size among them.
Yes it is but if you don't know what your velocity would be for any said bullet you're still just making a guess. I've had good luck with JBS once I have a load developed for making drop charts. My question is whether there's a way to get and or make an educated guess BEFORE you invest in new bullets and whatnot only to find out it's no better than what you already had running.

To answer your Question,..
IT, "can" be, a "Wash",.. sometimes,..
I shoot,.. a .270 WSM, launching, a 140 Grain, Berger Classic Hunter bullet, W/ a .528 BC at, 3,185 FPS
My son shoots, a lowly, slowpoke, 7mm-08 with, 168 grain HVLD, Bergers, W/ a .618 BC at, 2,760 FPS ( W/ StaBall powder )
Somewhere after, about, 600 yards, the "SloPoke" catches up to,.. "the LAZER" !
Both, our Bullets, EXCEED, 2,000 FPS at, 800 yards and with, the added weight of, his Bullet, it most probably hits, HARDER !
Go to, the Berger Ballistic Calculator to find out exactly, "where" his bullet catches up to, my MUCH Faster Bullet, if, you're really,.. interested.
Both, of us, shoot, 7.5 Pound Tikka's and the recoil, ( both, UN Braked ) feels about,.. the same !

It's considerably slower, but still, this is from a half-ounce sized bit of plastic at 15,000 mph...

Whatever charge weight is most accurate with your H1000 and the bullet you select regardless of velocity. What good is a 3250 fps velocity vs a 3020 velocity that shoots 1/2 the size group at ranges past 500 yards? Now I will go out on a limb and say I do not worry about B. C. until I go past 600 yards. If a caliber of hunting rifle does not have the energy past 500 yards to take a Mule Deer then why worry about BC, If your shooting paper way out yonder or truely long range hunting with a big magnum then yes pay attention to B.C.
From what I have read on numerous forums and such......speed is king. What does baffled me, why try to push for greater speed than the round is normally? That " I want 300 mag velocity from my 30/06". Why not just start with the 300 mag? I guess then it turns into " I want 300 rum velocity now".....
