This has been an interesting read. There really are no bad answers. All of us have different needs in a rifle from a decent deer file to fighting in the zombie apocalypse. My needs have been pretty simple, I hunt mule deer and not much else.
For the past 40 years I have been hunting with just one rifle. That rifle is an old tang safety Ruger M77 chambered in .243 Winchester. For years it had a Redfield 4X scope which a number of years ago I switched out for a Leopold Vari-X III 3-9x scope. It has been a deadly little rifle. If I do my part; it does its out to 300 plus yards when sighted in to a 200 yard zero.
I've taken a number of mule deer with it. I've not hunted elk with this rifle but at reasonable ranges with a good bullet I'm sure it would do the job but it wouldn't be my first or even second or third choice as an elk rifle.
So with that said I've decided to move up to a larger caliber in light mountain rifle because an elk hunt may be happening in the future. I have a Kimber Montana on lay away that I should bail out in the next few weeks. I plan on mounting a Leopold VX3i 3.5-10 or 4.5-14x scope. I've looked at a lot of rifles and decided on a Kimber because I think it comes closest to what the Winchester Model 70 should, over the years, become...lighter and trimmer. The Montana with scope should hit about 6 1/2 lbs.
The caliber selection was a bit more involved. Going with a number of .30 calibers like the .308 and .30-06 would make sense because of versatility and accessibility of ammo. Okay but aren't they just a little boring and so is .270. I'm not a "magnum" guy. At ethical hunting ranges you gain much other than getting beat up both body and wallet. I'm a bit of a classics sort of guy so 6x55, 7x57 and .257 Roberts can right to mind. All are deadly even on elk. If I was going with wood and blued steel anyone would be just right. In a stainless and plastic fantastic like the Kimber Montana an update of an old classic caliber seemed appropriate. It was down to the .260 Remington or 7mm08. I'm not much of reloader so I went with the 7mm08 because of the the wider selection of ammo. When you start stretching the range a 7mm08 doesn't give a thing up to the .308 Win.
I just hope when I'm all done it will shoot near as well as my old Ruger M77.
The old Ruger really likes Federals 100 gr. Nosler Partion load. This group from last years double check of its sighting is not unusual.
