I like to post a picture now & then with no text just to see what is said.
This bullet is a 45 mostly used in a 45 Colt cartridge. It can be sized .452, .453, or .454. It is a clone of the RCBS 45-270-SAA.
This is from a 4 cavity mould from HiHec made of brass. The bullet in picture weighes 290 grains & is cast from straight air cooled wheel weights testing 12-13 BHN, my favorite hardness for 20-30,000 psi loads.
The dark Stripe is lube. Cast bullets use lube & most have a lube groove. That's what you're seeing.
