I happen to have a box of Winchester WinClean 45ACP here. Let's see....It is shaped like a flat point, but keep in mind that the WinClean has an enclosed base and an exposed tip. The point is flat but your metal jacket doesn't enclose it.
I was in Wall Mart the other day and they had the Winchester 45 acp with what they called Blunt tip bullets. Looked kind of like a wad cutter to me. I didn't want to take a chance on them feeding properly so I bought the UMC Full jacket ball.
