RS is a sharp guy who knows a lot and has added a lot to this forum. Anybody can have a ‘too much coffee to be patient day’. All this stuff is about experience and opinion. The information he posted is good and I am not itrying to slight your choices. If they work for you, great. Here is my experience.
My personal take on R700 type actions is that they are about the last thing I would recommend to a person who is new to guns. They are okay if you only load them when you are ready to fire, but when the chips are down and the conditions are bad they may not fire or they might slam fire when you close the action. None of that is what I would consider a safe firearm. I’m sure that chaps a lot of people’s posteriors because they are the most popular action in the US. I have a buddy who loves them, despite having an ND that nearly killed his father. I don’t understand that but still respect him. I have not owned an R700 action in over 30 years and won’t.
I’m also not a chassis guy, but that’s more of a personal choice thing. They are not my choice to carry in either cold or hot weather because it’s uncomfortable even with gloves. While I do like vertical grips that result in good alignment for my trigger finger, I find the AR-type grip way down below the bore axis to be finicky for my shooting. Your mileage may vary because we are all built differently.
I also big game hunt, but my pertinent experience with Leupolds comes from carrying a rifle in my truck for coyotes during quail season. I bird hunt in the desert every weekend from Nov-Feb every year. I run through a lot of rough country from washboards, to dunes, to crossing washouts and arroyos. I am not a fan of having my zero wander by half a coyote at 100 yards. This did not happen from dropping or mistreating my guns. I struggled with it for a long time, and after reading about scope reliability on this forum, I tested it. It’s just the vibration from riding in the truck and it’ll push my zero by 3-5” @100. It has happed to me multiple times with Leupolds and every other scope that I’ve used except my SWFAs. They are now all I use, and I have a 3-9, a 6x, and a 3-15. The latter is my least favorite of the trio, but they all are scopes you can count on. I have considered Nightforce, but like the SWFA reticles way more and the lower cost. So I stick with them even if they are ugly and have giant turrets.
All that is my experience and opinion.
