Have a new Lyman manual for revolver cartridges and I have 150 grain round nose lead bullets. The manual gives data for a 150 Grain #2 Alloy, but the picture of the bullet looks different then mine. Almost like a wadcutter with a little nipple on the front. It lists 2.8 to 3.2 grains of Red Dot, which is what I have. But the OAL data it gives would have to be different since the bullet nose is shorter. The data for the 158 grain #2 Alloy has a picture that looks like the bullets I have.

Any help is appreciated.
