I'm sure this has been discussed and I pretty much know the conclusions but let's have a go at it again.
There are a larger variety of handgun bullets available than rifle bullets that there is no published data for, so what do we do. We can assume that a bullet that weighs the same is compatible for our needs, but this is not necessarily so. When I started reloading this is pretty much what we did.
A better more common-sense approach would be to examine all of the data available for similar size weight and profiled bullets on hand or find some. Some data listed is for HP, FMJ, as well as proprietary bullets, some data is bullet specific.
The bullets in question are Zero 10/40 165 grain and 180 grain FMJ, I also have Winchester 165 MC and no specific data for these particular bullets. These are the standard truncated of flat point 10/40 bullets.
But Speer has data for their 165 grain GDHP and TMJ, Lyman for the Speer TMJ and Sierra for their 165 grain JHP and JHP Sig V-Crown.
This should be enough information to load up some 10mm starting loads.
The Sierra data goes full tilt, and I am not recommending using max loads for any of these bullets.
