I’ve been loading for a few decades now and always try to keep close to the recipes from the manufacturers. However, it seems that all the data calls lately for magnum primers in 357 cases regardless of the poEder. I’m planning to load some 158 gr rnfp bullets on top of a light load of 231 for cowboy action. Ive got several thousand standard small pistol primers but fewer than 500 magnum. Am I flirting with disaster or irregular firing results by going with standard, non-magnum, primers?
