It is Finished

Shot all the smokeless rounds, pulled and dumped all the BP rounds. Waiting on Accurate mold to arrive to cast and load. The bullets above, do those look like they would be the Lyman 403168? Or something else? There is one on ebay right now but it's only a single cavity.

Couple of comments for you about the Lyman molds with respect to you 0.405 bore. 
1. The Lyman molds you run into, will most likely be single cavities for the big bores.  That is just my experience watching for them. (Editted in this) I do have several 45-70 Lyman mold models and all are single cavity.  The large caliber single cavity molds use the Lyman large handles. Can't image just how big a double cavity large bore mold would be.
2. Expect the diameters for both the 403168 and the 403169 molds, to be right near 0.403".  Obviously smaller than your rifle bore.  I don't understand this since I have never seen an original '76 or '86 in 40 caliber.  Don't know why Uberti went to a 0.405 bore.
3. The ebay mold is the correct Lyman version for the 210 grain 40-60caliber.  It is not for the 40-65.  Think I mentioned somewhere that I have an original 40-60 Winchester mold.  I wouldn't mind having a Lyman back-up mold but with 24 people watching, I don't think I would win because that price is going higher than that $25.
4. I did buy the true 40-65 Lyman 403169 mold off of ebay years ago, in order to have the 260 grain bullet to shoot out of the 40-60 like Dusty stated that he used most often.  The bullet drops out at 0.403 - 0.404".

If you want more production and 'also' the correct bore riding bullet for smokeless loads, than I would agree with you that a custom Accurate mold, will be what you will need/want.

Hope this helps you out.

PS - Those do not look like a true 40-60 bullet.  That front driving band is 'excessive' but could have been necessary to the design to hold the crimp groove.  That then has created an 'odd' nose profile.

Thanks for that input, BRS, kinda what I was thinking as well, about the bullet profile.
