I've been using it since around 1976-77 in 357 Mag, esp for jacketed 140-150 grain bullets. One of my favorite powders Have used somewhat for 44 Spec and 44 Mag. Have found it works great along with Alliant 2400 for reduced cast bullet loads in my assorted military bolt guns (303 British, Mauser 8mm, 7.62x54 Russian, 30/06). I've even used Alliant Red Dot for reduced cast loads in these rifles. All three of these powders produce good accurate and reduced shoulder slamming loads.
