I don't have much interest in most Weatherbys or RUM cartridges, WSSM's looked like an interesting idea, but why really bother?
The .375 H&H is now obsolete, but lots of guys use lots of obsolete cartridges and seem quite pleased with themselves for doing so.
I HATE the 25 WSSM, and the chasis it arrived in the m70 SUper Shadow. I've had a couple of them and the QC was abysmal. The 25 was deadly accurate, but couldn't cycle a round after firing half the time. As well, why not just make a 25 WSM??
SO, I will, eventually. GOt the barrel and reamer, just need a WSM Rem 700 or an Abolt donor.
