Just for fun,
I've had a "Comanchee" 45-410 for a while ,long enough to get bored w/plastic cases and go through the torture of making brass cases out of 303s and 30-40s. Then build tools to make it easier to make cases. I decided shooting long cases would make it more accurate than the 1 inch throat jump.
A friend picked up a Circit Judge and asked about 410 slugs. I thought rifled slugs for a 410 ? Too bad that thing won't handle that 460. Hey I just scored a 45 Maxi ball mould. That'd beat those 440 RBs . It looks a lot like a what a 460 S&W HBWC might look like. Oh and plenty of lube.
