I have gone to a heavier bullet in this design for 56-46 so this one will have to finance a mold for a different rifle.
With shipping I've got about $120 in this one so I'll sell it $100 shipped in CONUS.
3 cavity Accurate Molds #47-265S heeled bullet for Spencer 56-46.
Around 450 very pretty bullets cast from it.  Bullet preformed very well out to 400 yards.
 Would be willing trade for a 650-735gr .512 Postal or similar mold for my Sharps.

Anyway, I'm trying to see if I can duplicate the 700 yard accuracy that Marcot's book talks about so I'll have to reach for
the 310-320gr bullet the military testers used in 1864.  They also used a 400gr bullet but I'm not willing to risk that much weight.  320gr will do.
The heavier bullet might not be as effective as the 265gr on deer out to 200yrds (the 265gr is friggin' awesome on deer!) but the longer range for target shooting should make up for any over penetration it might have.  
Besides, how many animals can get back up and walk away with a .46 caliber hole in them?

I would also be interested in a bullet around 300 to 320grs,in one spencer sporter with a tight bore .458 groove I get better accuracy with the 300gr Lyman bullet ,trouble is this bullet is to  small for most Spencer sporters

Herbert,
Go to Accurate Molds online. Go to "Products and Prices" then to "configure a mold" in the left bottom of the "molds" block and from there you custom order the mold you want , you will select mold body metal, for a machine or hand casting, the # of cavities, sprue cutter type you want and mold number (write down the mold # you are wanting before you go there so you don't have to go back and find it.). 
There you can also make any mold changes you want like : diameter, bullet length, grove depth, ect... that you think would be better for your gun barrel.
The mold you are basing your mold on is: 47-265S.
You will need to add about 25% to the length of the heel of the bullet to get to the 300-320grs you are wanting or trim you brass shorter
in order to add length to the bearing surface on the bullet. Make sure that you leave enough throat on the brass to hold the bullet heel straight and firm even after crimping or you can cause it to become misaligned during the stress of feeding that will make it prone to jamming.
