I want to duplicate the factory load for the Speer gold dot 124gr.+P load for 9mm. I have been checking the net, but have not been able to come across exactly what I need. I have a boatload of W231, which I will use and the Speer 124gr gold dots which I have ordered. Starline brass and CCI primers. I have a Lyman 47th edition loading handbook which gives a max load in 9mm using a jacketed 125gr softpoint using 4.6gr W231, which gives 1099fps. and 31,500 cup. Speer shows the factory 9mm 124gr GDHP at 1150fps. muzzle, and the same in +P at 1220fps. muzzle. Any fellow reloaders out there with an opinion on this Lyman loading, or any of you have a better handload for duplicating the Speer using a different powder, I would appreciate the input. I could always buy a different powder. Many thanks. Wanna kill these ads? We can help!
