Another $0.02 opinion.
The .300 Magnum class of rifles, with maybe the .300 Savage at the tamest end, going on out to the .300 RUM, .30-378, the wildcats like .30 Tejas and others, all kick a bit to get the rounds out fast.
It's OK from a bench, where you're prepared and don't have to hold up the rifle, but many manly men flinch when shooting unsupported from the shoulder. The harder kicking Magnums make it (Flinch) more likely.
A slightly slower round, say 308 or 30.06, can easily get the job done at any reasonable hunting distance on deer, elk or black bear. In some ways, even better- Anyone ever seen the meat damage from a close in shoulder shot with a 300 Win Mag? Been there, done that and fed the bloodshot mess to the dogs.
If you're looking for a cartridge with greater killing capacity, check out the .33's or even larger diameter. They can do anything that a .30 magnum can do to an animal, and with less chamber pressure to boot.
Now, before I'm written off as an armchair expert, let me say that my chair has no arms... And I have a .300 Win Mag rifle (Browning A Bolt), as well as larger and smaller bore rifles. I load fast and slower (Relatively) rounds for it, and it's my most used hunting rifle. But as I get older, I'm less interested in the biggest/ baddest loadings and am leaning toward the .25 Cal. for deer sized game. Wanting to build a light rifle in .257 Roberts for Oklahoma deer.
If you're set on a 30 Magnum, I'd suggest a basic matte black finished Remington Sendero in 300 Win Mag. Durable and a bit heavy, but that's not a bad thing for a .300 Mag. Remington triggers are easy to work on and, after load work, if it's not as accurate as you'd like, setting the barrel back, re-cutting the chamber and re-crowning the barrel is pretty reasonably priced. There's more load data on the .300 Win Mag than just about any other .30 Mag.
Get good glass, otherwise you'll be wasting you're time on everything else.
Good luck with your purchase!
