Thanks for all the information guys. Kind of new the answer already that one of my current rifles would work. Just kind of want a new little bit better set up for this once in a lifetime hunt for me. As I said my wife took out a second mortgage for this so I want everything done right.
I agree with 35Whelen.
"I have a 270,30.06 and a 300wsm." For me go with what you already have, what you are familiar with, have most confidence with, and what you shoot the best with. I personally like a .270, with my next choice the 30-06, but.....I'm also old school. I'm building a .270 AI, hunt with a 35 Whelen and 358 Winchester. I'd say great, for the new rifle build
"if" you had/have time to get familiar with the rifle, shoot it and have confidence with it. Just because a rifle is new,
it doesn't mean that you cannot/will not have some kind of trouble with it; shtuff happens!! We've all bought rifles that didn't do what we
"thought" they were going to do. So now you have a new rifle, in the caliber and configuration that you wanted, and........there's a problem; inconsistency, fail to fire, fail to eject, whaatever. Now not only are you working on getting yourself in shape, getting all of your other equipment up and running, now you have to work on getting a rifle (that is having trouble) up and running and that's cutting into your time to prepare for the hunt; burning the candle from both ends!! Recently a friend bought a new Mod. 70 in .270WSM to go on a (once in a lifetime) mule deer/antelope hunt in Wyoming; he has a safe full of Model 70s however he wanted a new gun to take on this hunt. We went to the range, sighted the rifle in, and started shooting. He would get good groups then some really crazy fliers. He started getting these fliers, then started sweating and losing confidence in his ability to shoot. I suggested that he was having a bad day and to take a time out for another day. The next session at the range I was watching him shoot looking for possible flinch or something like that. When he fired I noticed that his scope moved, he had a broken scope ring!! Who ever heard of a scope ring breaking!!!???? He got it fixed, under normal conditions this wouldn't be a big deal, however he had the crunch of getting the rifle back up and running again. If you really want to buy something, perhaps buy a
really good piece of glass with good mounts to improve what you already have. JMO!! Good luck with whatever you choose to do and enjoy your hunt.
