Decided to load some full magnum loads for my .357 using W296.
Load data seems to be all over the place, haven't used it in .357 for 38 years.
Primarily use it for .44 mag. Only .357 load I've tried was 17.5 gr under a 158gr. JHP.
Bought some Hornady 125gr. XTP's and will be using CCI 350 mag primers.
Problem is:
Hornady's 50th. lists 16.9 gr's for 1250fps. and 19.6gr's for 1450.
Speer's latest manual lists 18.3gr's for 1188 and 20.3gr's for 1336.
My other 3 manuals, Lyman 48, Hodgden 2015 and M&R list 21gr's for 1357 and 22gr's for 1506.
I know these powders, 296 & H110 have a small operating window and your cautioned not to use to little but these spreads seem extreme for this powder.
