To get the effectivness of a cast bullet up to a JHP, it must have a wide meplat. None of the .45 acp cast bullet designs have a wide meplat, therefore I wanted to try bullets designed for .45 revolvers. I have not given up, because some of the old timers talk about using the Ideal/Lyman Keith bullet in .45 acp. My NEI mold for the Keith style bullets throws them about 265 grains, a bit heavy for the short acp case. 240 to 250 grains would be a better weight.TMam said:Just curious,
Why would you use that design and weight in a .45ACP? It would seem that it would be slow at any safe presure.
