What is important is CONSISTENCY from charge to charge, NOT how closely a given brand of measure comes to throwing a charge that weighs what a scale says! If you develop your accuracy loads by making, say "5-grain" changes in the charge as you work it up (or down), it doesn't matter if the most accurate charge for your rifle/bullet combination is a true 90 grains, or if it is actually 78.76 on a scale. What IS significant is how close yopu can come to reproducing that weight each time you measure out a charge. And, as you might suspect, this consistency or lack thereof depends on the OPERATOR of the powder measure, rather than who made it! IF you find yourself unable to do a creditable job of throwing consistent charges, then by all means use a powder scale! IF you are able to consistently throw charges that weigh withing 2-3 grains of one another, you are not going to get much, if any, actual improvement in accuracy if you weigh the charges to within 1/10 of a grain! This is just the nature of black powder! Please note that the old time bench and Schuetzen riflemen of the late 19th and early 20th Centuries, guys like Harry Pope, used volume measures, not powder scales, to set accuracy records with BP rifles that have yet to be equalled! This is despite the fact that many owned extremely accurate beam balances that they could (and would!!) have used, had they found that doing so improved their scores.

BTW, Wolfhound. An enviable group!
