Barnes TSX's in the Krieghoff Classic Double
I've read cautionary tales about using anything other than conventional lead core bullets in doubles, I presume due to the stress a solid copper bullet, or even a Partition, can cause to the soldering.
Is the Krieghoff Classic capable of safely and routinely shooting Barnes TSX's? I took my Cape Buffalo bull in April with a TSX from my .375, really like the TSX's, and I'm interested in little else bullet wise. I imagine, at least I hope, double technology and/or build strength has improved to the point the Krieghoffs can shoot any modern bullet.
I'm interested (one day far in the future when my wife allows I should add) in either a 9.3x74R Krieghoff Classic, or a .375 Flanged, if caliber makes a difference.
