Just went to check out a local good ole boy gun shop. Just a mom and pop ran place. I went in and asked if they had a black powder pistol measure. He said I sure do son, he then reached in his desk drawer and pulled out a brass adjustable measure that goes to 50 grains in 5 grain increments. I said thank you how much do I owe you. He said " put it in your pocket son, and happy shootin"
