Don't be happy with 2" groups. A bullet 1" low and a bit left, say, and one 1" high and a bit right @ 100 yards aren't even close to being within 6" of each other at 300. 7mm Rem Mag is the finest long range conventional caliber there is, IMHO, and should be capable of legit 4"- 6" groups at 400 yds.
