Im getting read work up some target loads of .357 magnum with 158 LRN and W231. I have found that some data calls for small pistol primers but a few called for small pistol magnum primers. I know I need magnums for IMR 4227, which is my next work ups, but didn't think I would need them with the W231.
Any help on this would be appreciated, thanks
