I took my Suspect Knight Brass Powder Measurer Today, to a Fellow who Owns a Blackpowder Gun Shop. He checked it against his, which he Know's is Accurate, and the Knight is Throwing 10 Grains(Volume) Under what the Graduations Suggest. If anyone has One of these, Just a Reminder to go 10 over for the Charge that you are Looking for.The Thompson Center was Right on the Money ! Knight is being very Conservative !
