Could use some help

[Ruger Dude]

Evidently I ran across this 357 mag, 158gr, LSWCHP load data somewhere. It was taken from the Hornady Handbook 5th Edition 1996. I do not have a copy. I will be using HP38 instead of Win 231. The Win 231 data has the last four loads listed as, 5.4, 5.8,, 6.1 and 6.4 grains. This seems a little hot to me. All other (HP38) data I have found has 5.0 as a max load with this projectile but that is more recent data. I tested the HP38 5.0 grain loads but wanted to try a little more velocity to see if I could get the HP to expand. I loaded up (12) test rounds of 5.8 grains of HP38 under the 158 gr. LSWCHP but after a little more thought I decided that was a pretty big jump from 5.0 gr. My plan now is to drop back to 5.2gr. and work up to 5.8gr.charge. I wanted some opinions from those in the know about this data. Do you think working up towards 6.4gr. of HP38 is a bad Idea? Anyone have a copy of the Hornady 5th Edition that could look up this data? It may be 357 mag rifle data which is what I expect. Being as the data is from 1996 it may seem hot because of the change in pressure gauging. I got lucky today. The 5000 Cheddite shotshell primers I ordered back in January for $29.99 a hundred where shipped to me. Not too bad at today's prices. They are $37.00 a hundred right now.

I was overcharging my 44 by using an old manual. Heres what Hogdon recommends.

Look at the differences in pressures between the XTP and the LSWC loads above. They did not stop increasing charge on the LSWC because of pressure.

Good point. Funny thing, checking the differences in pressures came to mind while I was sleeping. I knew I was missing something hence the question. Kind of obvious now that I see it. Thanks for the input.
