Went yesterday and tried a new load in the 357 rifle. Used WW296 power. Did a work up and it turned out to be 21.0 grs. was the best, with a Speer 125 gr. HP . A 3 shot group .352" at 50 yds... It is going about 1900 FPS. I don't now about other peoples 357 rifles , but mine likes .355"Dim. to 357"Dim. bullets. It don't like the .358" Dim. bullets like SWC at all. I get good groups with everything but the SWC is all over the board no madder how slow or fast they go.
