What do you suspect is the main reason for the velocity difference?
Extra capacity due to the hollow base in the Huffaker bullet. If I seated the solid base bullet out further (if I had room to do so) it would lower the velocity.
Those Killebrew bullets look as if they would do some serious damage to a living critter.

My first achilles brass was magtech brand with the cannelure so I was quite restricted in choice of length.....but the cannelure made it easy to cut.....

Were you guys thinking about that when you decided on the case length? That CB Special would be the proper length? Or are we in lucky territory here? I'm not complaining ... just curious.

Mike Haas at AmmoGuide.com was interested in the cartridge, but said what's on here "doesn’t include the basics of what I need to add to AmmoGuide – a simple case diagram or even a table of the external case dimensions. I think I picked up that the case length is 0.9” but that’s about it. Is this a shortened .45 Colt using a .476” heeled bullet?
But if we can figure out the case dimensions and a decent description, we can add it."
Anyone who knows more details about it might want to go there and message him the information.
(AmmoGuide is a cool site for both factory-load recipes, as well as user-submitted ones, but the real forte is very flexible cartridge comparison tools and things like picking your favorite cartridges and seeing what suitable powders they can all use, or printing ballistic or dimensional comparisons.)

No .. We were not aware of that cartridge.. I am not sure if it was being made at that time or not. We looked at the .476 Ely which is the largest factory caliber the Colt SAA was made in and decided to make our cartridge a similar length. The .476 Ely was .88" ... the 45 ACP (which we were attempting to duplicate ballistics) is .898" .. we decided a round .900" would be good.
EDIT: the cowboy cartridge will work just fine though a few thousands shorter ..
