Those are Lyman 452374's In my opinion one of the best bullets for the 45acp.
But you should try them in HP's
The only issue I have run into with these is lube sizing them with a Star Lube sizer.
They tapper just in front of the front lube groove. I get lube on the nose from the star sizer.
That does not happen when lube sizing from a RCBS LAM or a Lyman lubber.
Other than that they are top 10.
