I picked up a 460 S&W Magnum a few weeks ago, and I can tell you that there is definitely some odd reloading data out there for it. I'm going to have to be very careful working up loads for it.
I bought some 300g Hornady XTP-Mag bullets and Hodgdon's Lil' Gun powder to work up some loads with. But, having looked at multiple data sources, I discovered that there are significant differences in the listed starting/maximum powder charges between the different component manufacturers. For instance, the Hornady data for this combo lists charges between 29.3g and 38.4g. But Hodgdon lists the min/max for this combo at 40g and 44g.
That's right... The STARTING load given by Hodgdon is higher than the MAX load given by Hornady.
So... what do I do with that?
As a comparison, Hodgdon's data for their other powders listed for this bullet (Win 296, H4227, and H110) all overlap the Hornady data - some more than others. I can understand one manufacturer's data being more conservative than the other's, but the difference in the given loads for Lil' Gun has me baffled. I would think they would overlap at least some.
Is this something fairly common that I have just never run into before, or is it a rare case?
