Has anyone noticed a rifle handload smoke? My load is .308 Winchester. My recipe is 38 grns of IMR 3031 pushing 168 grn Sierra Matchking. According to the Lyman 49th Edition Reloading Handbook, starting load is 37 grns and max load is 42 so I'm within my safe perimeters. What got me is the smoke from it. It's smokeless powder after all. That's why I'm here trying to figure out if something may be wrong with that tub of powder. Has anyone on here come across anything like it before? Thanx in advance
