Whomever rechambered this barrel to 300RUM is the idiot responsible for the explosion.
The chamber is only 1" in diameter on the encore barrelsand the RUM case is .553" and that leaves .220" of steel to surround the cartridge. No wonder it exploded.
This is why TC does not chamber the RUM's. They aren't designed to handle this kind of pressure.
Very good points. I have a Virgin Valley Encore barrel in 300 WSM, BUT it is a full bull contour. The VVG guys also recommended that I only shoot factory ammo and not hot reloads due to pressure issues.
It is just fortunate that no one was hurt in the explosion of this barrel.
