.357 Magnum 10-inch Contender Barrel Reloading Data

Load Image
Warning! Notes: All loads crimped in crimping groove or cannelure provided. All data the result of a single representative 10-round group, fired from a sandbag rest. Velocities were measured 10 feet from the muzzle with an Oehler Model 33 chronograph. All cases .357 unless otherwise noted. Update: Alliant Powder Company does not recommend Blue Dot in the .357 magnum using 125-grain bullets. Recipes for heavier bullet weights are acceptable. Their new tests on recent powder samples have shown high pressure spikes that can damage personal property or injure you. For this reason we removed all 125-grain Blue Dot data from .357 magnum tables. (Handloader Issure 168)
