I'm thinking of trying some of the Norma r123 they have on clearance at Graf's for .357 Magnum. The Norma website is not usefull as they only have load data for rifle calibers there. Graf's does have the Norma manual but I don't wan't to spend $25 just to try 8 oz of the powder.

125g JHP
15.8 grains to 19.3 grains

158g JHP
12.6 grains to 15.0 grains

Thanks.
