Ok I just purchased a new Rem 700 ADL 7MM Mag. I bought it for the action mainly. So I have a Long Action with a Mag Bolt. I am looking for a gun to hunt Elk and Deer (never hunted Elk). So any recomendations on caliber. Or do I tru the action and Barrel and put on a new stock and call it good?
If you are planning on swapping the stock regardless of which direction you go with it, I'd go ahead and drop it into whatever stock you were planning on getting for your build, bed it, float it, swap the trigger with a Timney or Jewell, and do some load development and see if she'll shoot...It's worth a try, right?
I'm guessing it has the 9.25" twist, so I'd stick with the Berger 168 VLD's for now, just to see if you got a shooter. Use some new brass that will form to that chamber (I recommend Nosler). As far as powder, anything Reloder 22 or slower should work. I use 7828 SSC in mine. But the new 7977 will also work great, as well as Reloder 25 and H1000.
Also remember, that is a cold hammer-forged barrel, so it will take 50 rounds or so to really get broke-in good. Make sure you really scrub the bore good before the break-in and make sure it's as clean as it's going to get. Another helpful option would to load up 50 of the Tubbs Final Finish bullets, and shoot them in the correct order, and fire-lap the bore taking all the factory tooling marks out. You can break-in, and lap the bore at the same time. I have been told those bullets do improve accuracy, and when you smooth out the bore, you might even gain a little bit of velocity.

If that barrel will shoot good, the Berger 180 Hybrids should stabilize in your barrel if you have the 9.25" twist, and I would work up a load for those, since you added Elk in the mix of potential game. For deer, the 168's work fine, but the 180's would also work good.
