My dad gave me a Cimarron revolver in .45 Colt a few years ago, along with a box of 100 rounds of loaded ammo using 6.0 grains of Trail Boss and some 250 grain cast boolits he bought off of Midway. He gave me an extra box of the boolits and I just used the last of them.
They were unique in that they were 250 grain and had a diameter of .455. They were very accurate in every .45 Colt firearm I've shot them in.
Can't find them anywhere and no idea what they were...
