Brand new in the box never fired 338/300 (EDGE). I recently purchased this XCRll 338 ultra mag and had Mark Moffit of M&M Guns re-chamber it to except the 338/300 Edge cartridge and to do a cut in muzzle break. Mark is well known for building competition rifles. I've since decided to build a custom 338/300.
This is considered to be one of the finest most accurate long distances cartridges made-plenty of energy well past 1500 yards using a 300 grn bullet.
There is approximately $1500 of value in this rifle, I'm willing to take a hit on this, I'll sell it for $1100 shipped. (SCOPE NOT INCLUDED)
For some good information on the 338/300 go to a web site called Defensive Edge 338 Edge - History and Development ..:efensive Edge - Custom Gunsmithing::..
also there is a good article on the 338 Rum, Lapua and Edge on the web site long-distance-shooter Long Range Shooter| The 338′s: RUM, Lapua, & Edge by Lucas Beitner 2009.
