Default Help me with Barnes XPB and hp38

Can't find any load data for these bullets with hp38 in 125gr 357. I bought them to keep in my sidearm while hunting in the lead free zone. Hp38 is what I have on hand. Any recommendations to data? Get a different powder? Google fu not working for me? Thanks all

I am not saying to follow the following, this is just how I might approach the problem if I was faced with the same challenge.

The Hodgdon site lists 125gr Hornaday XTP (relatively soft HP jacket) and W231/HP38 at a start load of 7.3grs (1335fps) and max of 8.5grs (1559fps) with a mOAL of 1.590". The only problem with using Hodgdon's OAL for the XTP is XPD's are probably going to be longer, so the finished cartridge OAL will likely have to be longer to keep pressures in line, at least as you approach max loads.

If you could get the OAL of a 125gr XTP bullet and subtract it from the OAL of the 125gr XPB and add that difference to the Hodgdon's load data's mOAL, you would then have a mOAL that should reasonably replicate the pressures of Hodgdon's XTP load for the XPB. You then would just follow regular safe loading practices working up to max and looking for pressure signs.

Of course, there is probably a simpler approach, like calling Barnes...

Good luck, have fun.

Thanks Bill. There's a simple approach and an interesting one. I may have to try both.
