I'm getting lots of good feedback on this bullet. One thing that I hadn't paid much attention to, till it was mentioned a couple of times, is the ease that it drops from the mold. This is one very fast casting design. It's one of the few that I use two molds for because one mold takes too long to cool enough for a good sprue cut.
The relatively fragile driving bands lend themselves to easy lube/sizing to exact chamber sizes. Some Italian clones have chambers running as small as .447". This is one design that will size that far down without deforming, and give a nice snug interference chamber fit.
On the other end, it drops big enough that I can lube/size them to .458" for Plainsman events with my 45-70 Remington rolling block rifle.
The flat nose (Thank you PUK for that idea) allows for use in tube magazine rifles when loaded in Cowboy 45 Special, Schofield or 45 Colt brass. Naturally, they shoot great in like chambered pistols.
Now, there's an article coming out in the CC, as soon as I get the photo work done, about shooting the DD-PUK FLAT in 1911 45 ACP pistols. This bullet feeds flawlessly and shoots very accurately in them. For a real treat, try this rig with Black Powder. With all that lube it'll run forever before it needs cleaning.
