On the argument that the 1892 is the strongest rifle action, I find that hard to believe too.
Take a look at a 99 Savage action sometime. When it is closed the reciever and the bolt are pretty much jammed together into one big block of steel that is pretty much in line with the chamber. I don't see any way that a '92 action could possibly be that strong. The only thing against the '99 for use with a .454 is that the action was designed for full length rifle cartridges so it probably couldn't work unless scaled down. Plus you'd have to butcher a lovely rifle to start with. But I'd bet money the action is strong enough and then some.
Probably the only reason that the '99 isn't made anymore in any caliber is price.
On the Marlin 1894's, I also bought one that wouldn't feed any ammo from the mag other than .38 SPL. I took it back for a refund and the shop sent it back to Marlin. It was still brand new though - I hadn't fired a single round through it. IIRC, the issue was something to do with the extractor.
Still, the QC issues bother me on any gun that doesn't work right. For that reason, I prefer to buy used if at all possible.
