It was smart of you to ask the question, most people just drive right ahead. That being said, even if you had a large shank Lapua action I think this is one of those times where just because you can do it it doesn't necessarily make it a good idea. I've seen lug setbacks and threads deform on savages so badly you couldn't unscrew the barrel in as little as 500 rounds. Truth is there's only two 700 size actions I personally would trust to hold up to a Lapua long term, the Defiance Deviant Tactical and the Terminus Zeus. With the powder capacity of a Lapua, you're basically putting your cheek in front of a hand grenade and setting it off. You want as much strength between you and it as you can get.
