Re: New Rifle question
As important as the rifle is the choice of cartridge. You mention a variety of hunting conditions. The cartridge that you like and will fit all of the conditions is an important consideration.
Any of the factory offerings in the Sendero class of rifles from Remington or Savage and other manufacturers will serve you well . . . if your luck is good . . . and if you handload and do some tuning.
I feel the advantage of a higher grade rifle such as the one you mention is a better choice due to many factors. Most important factor is consistent quality. Pick one and it will shoot! Next important is that you only spend the money once, unless you are a collector of stuff and enjoy looking at the many rifles in the rack.
Also something to think about is quality scope mounts and scope.
I've found that going high grade is overall less expensive in $ and time. Quicker getting loads selected. Shoots good for a long time. And more robust when much transport is involved.
I may be the slowest guy on the mountain . . . . but . . . . I'm on the mountain!
