I've had a Cimmaron 78' for a few years and they truly are a tank, as was mentioned. I'd even go the route of re-barreling to .450 Nitro if I had a spare one to play with. I did the same with a CZ Ringneck, and the 78' is built strong enough, it doesn't need a third fastener for that. They accomplish nothing anyway. One thing I DID do with mine is strip the awful poly-coat off the walnut and re-stain, but not before lopping off that equally awful flared forend tip and re-contouring it to a proper style. She does well with .735 balls and 7 drams of black just as she came out of the box, and for pesky snakes is wonderful with dove loads. I don't hunt anymore, having left that in the past, but I do love building, and I might just get another one to cut up and solder back. I have completely disregarded the 'china' factor when it comes to these. They may be the only thing I've ever done that with, apart from perhaps 'china' chainsaws. They are not 'pretty', or engraved, but the basic block of steel is there for going at it.
