I had the same glowing first impression with the first .30-378 Weatherby I built. Had to have one for myself. Bought an action just for that purpose. After a year or so of shooting other people's rifles in this caliber, however, I decided it was too much of a good thing. An extremely unpleasant firearm to discharge - loud, harsh, lots of muzzle blast. Short barrel life. I finally decided that if it was too far away to kill with a .300 Winchester, I was going to try to sneak closer or pass the shot.
