Is there any place where I can get a historically correct mold for .44-40?

Are you thinking about the old original "IDEAL bullet mold & reloading combination tool"?
In that case I think eBay and gunshows are your best bet.

If on the other hand you want a modern bullet mold that casts an authentic flat-nose bullet with proper grease grooves, then LYMAN still makes those.

Lyman 427098 is a historically correct 44-40 mold. 2 grease grooves and no crimping groove.  Mine usually drops wheel weights at about 200 gr, pure lead closer to 205gr.

Unfortunately it seems that that mold is out of production.

9245, ifin you are set on the Lyman style 427098 mold for a 44-40, if ya can't find one somewhere, in case you have or haven't heard of them, try NOE Bullet Molds (online store). They are a quality maker of both aluminum and brass molds of alot of rifle and handgun calibers, many of them similar to alot of bullet designs from yesteryear. They are very good, excellent quality with high fives in the bullet casting fraternity. I have two of them, one a .257 diameter (250 Savage) rifle mold and the other a 45 Colt mold (.454) for shooting in my Kirst cylinder Colt 3rd Model Dragoon conversion. They aren't cheap, but nor are they overly expensive. Similar to RCBS and Lyman prices. NOE has alot of variations of about every caliber you can think of in style and weight, 2-6 bullet molds. Might not have some extreme wildcat caliber, but from looking at all of their offerings bet you could find something similar to what you are looking for. Friendly helpful staff if you need to call. I talked with the owner once and ya couldn't find a nicer guy. Besides bullet mold talk we talked about a whole host of things. You wouldn't see or get that with any of the 'big name' outfits selling shooting needs.
