Id choose the gun by what feels best to you. Id go to the shop and shoulderall and check the trigger feel also. I like the A-bolt in a landslide but thats just my opinion. It has better stuff right out of the box the rems and rugers.

And for caliber holy crap as many people will say th 06 as the 7mm mag. The 7mm is shoots a little flatter and is better at longer ranges and the 06' has prob the biggest bullet selection in factory loads you'll find. I dont think you'll go wrong with either.
