Easy choice--NPR1. An MOA reticle will serve you much better in the long run. NF also makes combo ballistics turrets (MOA and yardage markings for your load in a given set of environmental conditions) for the NF made G7 Gunwerks scope. Go to gunwerks.com to see them. Perhaps you could order a NF G7 Gunwerks scope with and NPR1 reticle, I don't know.
Why MOA? If you need to do a quick adjustment for your second shot, if your spotter understands the very easy MOA system, he can just tell you what to adjust in MOA (up, down, L or R) and you can then use the reticle to do that, precisely. With the the Velocity reticle, and any ballistic reticle, how to you make precise and quick adjustments for second shots? Even truly precise first shots using the reticle, are going to be questionable.
Ballistic reticles are meant for the digestion of the masses who do not truly understand ballistics. And, the fact of the matter is that you really do need a ballistic computer program, such as Exbal, that have the various reticles in the software to even know where your load will hit in a given set of environmental conditions.
Can you tell I don't like them? Like yardage marked turrets that are only good in one specific set of environmental conditions, the same is true, but on an even less precise scale for ballistic reticles. If you really delve into ballistics, turrets, reticles, etc., you will start to understand the inherently imprecise nature of yardage marked turrets and ballistic reticles. They do work, but I have always thought that that fill a market niche often (not always true, but often so) for folks that don't want to put the time into truly understanding ballistics and so find this seemingly great shortcut.
I don't think we should be taking shortcuts when shooting game. If you really understand ballistic reticles and yardage marked turrets and their limitations and have a ballistic computer to help you adjust the ballistic reticle to differing environmental conditions, then they are fine. But I have found the folks I know with ballistic reticles, in general, don't do those things--the result is imprecise shots. All at the time when they think they've got this great long range system.
A basic tenet of true long range hunting is to use a heavy for caliber, high BC bullet that still works well on game.
With that in mind, you should consider shooting a bullet of at least 200g such as the 200g Accubond, 210 Berger, 208 Amax, 240 SMK,etc. Even better would be the 230g Berger. Many very experienced long range guys here will tell you that the 230g bullet is just about perfect for the size 300RUM chambering to maximize it's potential energy at long ranges. Spend a little time on a ballistic calculator and this becomes very apparent when you check energy and wind drift numbers at long range. It is very hard to convince folks, that do not really understand long range shooting, of these simple facts. Your 180g bullet will not perform nearly as well at truly long ranges in terms of retained energy or reduced wind drift as the heavier for caliber bullets mentioned above. Go for the 230g Berger and don't look back, would be my advice.
Good luck!
