Are there any reloading manuals that recommend standard small pistol primers for a 357 using Alliant 2400. I'm wanting to load some 180 grain XTP bullets and Hornady's manual uses magnum primers for everything. Alliant's reloading guide only goes up to 170 grain bullets. Not wanting to experiment. Just want safe reliable load data. I have 1000s of standard primers and can't find the magnum.
