The answers to some of the questions you present are facts others are opinions.
I use Shock Waves for long range target and also for hunting spots where I expect long shots.
The best long range hunting bullet is the 50/40 200gr Shock Wave and this is backed up by a combination of flatness of trajectory caused by a combination of a good BC and SD and the velocity that is obtainable with a reasonable powder load. And the fact they do a good job on terminal ballistics.
The standard 250 is a very accurate bullet and I use the for target and
'0" ing for hunting, I no longer use them for hunting as they tend to break up and not leave a good exit hole which can be a necessity for a good blood trail, I recommend the bonded Shock Wave which does hold together and shoots the same POI.
There are some people using the 300gr for a 200 yd bullet and doing well with them, They do have a good BC and SD but their muzzle velocity is down when compared to the 200gr 50 /40 but when I have the opportunity to hunt elk or moose or big bear I switch to them. My normal opportunities only include deer bear and boar and a drawing for elk.
