I have a Rem 700 Long Action that I'm considering cannibalizing and building off of. This will be a long process, acquiring parts as funds become available, I'm thinking 2 years, maybe more, we are building a house. This will be for my Wife and Kids (when they get old enough). I want your opinions on what caliber. I should probably back up and try not to lie to you all . . . if I'm building a really nice custom, I'm going to shoot and hunt with it quite a bit. Requirements: Light and not too much recoil (without a brake). I'm hoping that, since this will be built in a LA, that I'll be able to seat whatever bullets work best in this rifle almost to the lands and keep them fitting inside the magazine. Ideally, I'd like the round to be good for Mulies and Elk, but the Elk shots would have to be slam dunks and stars aligned, so mostly, I want a lightweight Mulie gun. Action: R700 LA Barrel: Proof Stock: McMillan Carbon Trigger: Jewell Bottom Metal: Undecided, but assuredly DBM Scope: Leupold or Vortex $800 - $1300 Bases: Undecided Caliber: Help Please Thanks in advance.
