I have a new savage 12 in 204 that I am working up a load for. I have been putting some groups under a dime with H-4198. Seen on the net that alot of guys seem to like 4895. I had some that is about three years old. I have been keepingall my reloading stuff in the house. The powder had a yellowish green tint to it, but I cant remember what it originally looked like. The can smelled like a strongnail polish smell. Here is what really stood out at the range. Most of the shots had a long smoke trail that was on the same path as the bullet, sometimes twenty feet past the barrel. It was about the size of your thumb and quickly blew away. So should I assume this is bad powder. I also opened up a fresh case of CCI 450 but do not think this is a ignition problem. Any thoughts from you guys, just wanted info before I toss it.
