Have a Accurate hand loaders booklet 5th edition. For 357 rifle usage the lightest bullet weight recommended is no smaller than 140 gr.
Although in there 3rd and 4th editions. It states the 125 gr. bullet can be used for rifle.
The info below is from Accurate Powders 4th edition Loading Booklet:
Suggested cartridge brass & primer are >Winchester.
No. #7 min 10.8 =1513 fps.
No. #7 Max 12.0= 1680 fps.
Please consider. The current reloading Accurate booklets do not list nor suggest the 125-gr. jacketed bullet weight be used in rifle applications.
