That is interesting. Thanks for sharing. The gent put together a nice rounded site about one of the most interesting subjects there is Leverguns and their cartridges.

A friend of mine seen a YouTube video on the comparison between a Henry 1873 (from the New current Henry Company) and the Uberti 1873. It was where they disassembled them and compared the internal parts, etc. Some of the parts inside the Henry 1873 they thought to be investment castings, whereas the Uberti were all machined. They they said the quality Uberti parts and workmanship appeared better then the Henry. Just saying, not pointing out which is better. I'm just glad we have all the gun manufacturers in today's climate.

Nothing wrong with investment casting, if it's done right - Ruger's frames for example.

A better stronger method, but more expensive, is forged.

CPM……another form of powdered metal……is incredible
Like T-15……the baddest High Speed Steel known to man. And mainly unknown to most machinists
Tempered to 67 RC

And mainly unknown to most machinists Tempered to 67 RC I don't want to get into a pissing contest, but O1 & D2 steels are pretty damn good and hard too and basically cold worked which is a forging except at normal temperature then hot forging. |

I never had a problem with MIM parts in the Smith & Wessons I've had. I read about it some years back and moved on. So you might say that I don't have a problem with MIM parts.

The point being is that a Winchester 1873 is an interesting rifle and the 44-40, or 44 WCF, is an interesting cartridge.

The history read was WAY cool! Especially loved reading about the old primers before Winchester started their own.

If you look up grid ability of T-15……….. O1&D2 both grind with regular grinding wheels much easier than HSS T15 takes CBN, the CPM T15 grinds like HSS Non CPM is considered the transition between HSS and carbide Grinding 45 years Brought the first grinder to Linebaugh’s shop almost 30 years ago You want no part of T-15.
