I've never used a scale for BP loads. Black powder is measured by volume. I've been a life member of the National Muzzle Loading Rifle Ass. for 42 years and shot on the national range for 30 and have never seen anyone use a scale - it's always been volume. The old, or even new plastic adjustable measures will work just fine. I to would buy a Mec Jr [ 600 ] - they're cheap and it's fun to load your own. That way you're not trying to fine expensive loads. Shotgun world is a web site that has a reloading forum that's very helpful for a first timer. Good luck - Paul
