A buddy gave me 4 lb. of IMR4198. It is pretty old, still in the metal cans. The only cartridge I shoot that has loading data for this powder is .223. I usually load .223 on a Dillon RL550 with the Dillon powder measure using H335. For the IMR4198 , I used a Hornady powder measure off the press since it can shear grains. I loaded a few rounds and they worked OK, so then I loaded several hundred rounds. My powder measure and the funnel over the powder die got coated with rust residue. It is coming from the inside of the can. It was enough to make the powder measure "sticky".
Are there any issues with burning rusty gunpowder?
