The Match-Grade Model 3BR was designed to be the ultimate powder measure, ready for competition straight out of the box. Since its inception, this powder measure has been instrumental in helping silhouette and benchrest shooters win matches and set new records. Its development was based on the time-tested accuracy and reliability of the original Model 3 powder measure. The Model 3BR Powder Measure incorporates all the features of the original Model 3, with added conversion features specifically sought by benchrest shooters. It quickly became the most popular powder measure for two key reasons - its wide range of charging capacity and its proven performance record. Additional metering chambers are available, including a handgun metering chamber with a charge range of 0 to 10 grains.
