So taking this information into account, I have decided to bite the bullet and buy this - Vortex Optics Viper HS 4-16x44 Scope to put on a Sig 716 .308 Patrol Rifle, and leave the Burris on the .30-06 that I talked about earlier. But, I may take the Sig 716 Antelope Hunting this year instead of the Bolt gun I referred to in my earlier post. Sidecar Flip gave me very good advice I think.
I've always had great success with Burris as a hunter. I have a 3-9 Fulfield on my .243 deer rifle and the 4.5-14 version on my old 300WM elk rifle. I've killed many, many elk and deer looking through a Burris scope. If not having a $1000+ scope means you can't bag your game, you've got bigger problems.
I also went with Burris because they are a Colorado company with great customer service. I used to work at a gun shop in Littleton, CO and all the old timers, including Corky the owner said the same thing.
I'd run the 4.5-14 if it were me, you won't notice 1.5x at the low end, but adding 5x at the higher magnification surely can't hurt.
I have a Burris Full Field II 3x9 on my .30-06 Remington Model 700. The rifle has been bedded and accurized by Dave Sullivan at Wind River Rifles. I always hunt with Barnes Vortex Ammunition. I have taken Antelope with it three years in a row, and a Cow Elk last year. None of these shots have been more than 200 yards.
This year I drew a Bull Elk tag in Area 13 Near Craig Colorado, which may require much longer shots, due to the openness of the terrain. I'll be hunting the 4th Rifle season, which pretty much guarantees some snow on the ground. I will also be hunting Antelope on opening day in Wyoming just north and west of Cheyenne, with a buck and a doe tag but that could be in 80 degree weather . . . October 5th. . .
I have a Burris Fullfield II that is a 4.5x14 scope that I intended to mount on a Kimber 300 Win Mag, but I have never fired that rifle, since I won it in a Wyoming Wildlife raffle and it is a RH Rifle and I shoot left handed.
So, for the hunts I am planning this year, should I mount the longer 4.5x16 on my go-to rifle or just leave well enough alone?
When you go out on the plains or looking across canyons in the mountains you want the highest quality glass you can possibly afford and better than 9x magnification.
Be prepared to shoot farther than your thinking you will because you likely may well have to.

I would keep the Burris where it is at, I have the 3-9x40 on my 22-250 and have bagged varmints at close to 500 yards with that setup. A lot will tell when you start shooting at the longer ranges, if you aren't comfortable to the distance you practice with the 3-9, then by all means move the bigger scope onboard. Me personally, I use a 2.5-8x36, on my 300 Win Mag, but right now I only shoot to 400 yards, I want to get to 800, so I am looking at 12-14 on the top end now.
If you're only trying to get to 400-500ish on big game then the Burris should be good enough. No doubt it has a plex-style reticle in it, and in a second focal plane system that reticle can be used quite effectively for downrange zeroing and windage applications, and not bad for rangefinding apps.
