Berry's website recommends you use low to mid range datea for jacketed bullets for their bullets / but you need to use data for a similar profile..
In the 158gr RN - I think Berry's is advising you to use the XTP data
and in .357 mag Hodgdon TiteGroup calls for 5.4 min / 6.1 max. For Berry's RN 158gr - I've loaded a few / and have been using 5.6 gr of TiteGroup with good results in my guns. When I use Montana Gold bullets / 158gr CMJ ( which is a much harder casing ) I load them up to 5.8 grains.
Hodgon data say .38 spl 158gr XTP 3.5 min / 3.9 max and I load mine to 3.6 because I'm looking for a light load for the grandkids to shoot. Cast bullets ( 3.2 to 3.8 in their data ).
I don't load any lead bullets - so I can't give you a personal recipe there.
