Ah, I miss Inyokern. A great range site nearby, where I spent many happy hours--and we can't forget Inyokern International Airport.
I almost said something dumb about Lyman #452488 when this subject first emerged, but uncharacteristically stifled myself until I had access to a better puter than Marie's cranky laptop. That thing would be a better target backer than digital device.......where was I? Oh, right--#452488. One of my first Lyman purchases in 19-ought-81 was a mould to make 45 ACP bullets with. The only thing Berman's had in that diameter was a #452484, a gas check 225 grain RN that looks a lot like #452374--but isn't. The gas check shank is superfluous for 45 ACP, but I bought some anyway. That got old in a hurry. I think the bullet design was meant for the 45 Win Mag. I soon acquired a "374", and the differing nose form was noticeable--i.e., the "374's" ogive radius is a lot longer. Somebody in later years wanted #484, and off it went.
