I was wondering if anyone has used Ramshot Hunter in one of the big guns (416 Wby, Rigby, or 375 RUM). Many of the other powders listed are compressed, I don't care to load over 100-102% capacity. My worry is igniting 100+ grains of spherical powder. Ramshot claims that there powders are "specially made" to be more like stick powders thus not to have ignition or temp sensitivity problems. Has anyone used them to back this up?
