I have always used either a Mod 700 Classic it seems or a Winchester 70 FWT Classic in 25-06 to 300 winamg on mule deer, cause that's the way I like to hunt, up in the edges of aspen/black timber. Over the years I've had all sporter weight rifles in 7mm Rem & RUMs, my first 300RUM, 338 RUM, 340W (ultralight) 338WM, several 300Wins, all good, never killed game with any of them over 375yds! For grins a few years back, and my last rifle set up for long range hunting was a simple Mod 700 SPS SS, in 300 RUM. I had it Pillar bedded in the factory stock, Timney Trigger installed, muzzlebrake added. I had an older leupold VIII in 4.5x14AO sent off to Leupold and had their CDS turret added. I had it set up for the Nosler Custom factory load with the 180PT (this load shot an honest .5" out to 300yds, never shot it on paper past that, just rocks way past) . It worked out to dial in right to 900yds. It weighed right at 10lbs all up and ready. I din't have a lot of money tied up in that rig, and it was my last, never hunted with it, sold it all. I decided I was changing my hunt methods, etc. Getting older. Now, I have a long range capable Mod 700 in 358 Norma Mag (especially with the Barnes 180TTSX DoubleTap ammo, but I will end up using 200-220 Barnes & Hammer) handloads), 25" #4 Shilen in a Brown Precision High Country, Nikon 4x12 on it that weighs about the same, more like 9#. I "can" shoot way over there, but I don't. I just like to hammer elk from up close to a max of 400...that's as far as I want to pack one out, ha. So, lots of rifles 'can" work out for your specs, and won't cost anywhere near $4500...but if you got it, want it, that's enough reason! For sure, if one wants to regularly take game past 400yds, every $dime spent resulting in accuracy is worth it. Good luck to you pard!
