Most 'gun guys'(or gals) should be able to name 40 or so 'ideal' deer rifles. After we get the cartridge figured out, we can work on the platform, barrel length and sighting system.
One has to factor in the different types of hunting, are we covering the SC bean field or in a cedar swamp up north? The next is covering a brushy river bottom in NE.
I'm more of a tighter cover hunter, shots average 25-125 yards. I like lighter weight, compact rifles, medium powered scope. I am almost awash in deer rifles. I really didn't have much of a reason to deviate from my boyhood Model 70, in 308.
Since I'm a gun guy, I deviate. It would be boring if we all carried a Savage 110 in 30-06. Most often I use my 20" barrel Browning Micro-Hunter in 284 Winchester. It's light & compact. Most of the time I'm not in a blind.
I'm big on proper shot placement too, another biggie.
