The Match-Grade Model 3BR was created to be the ultimate powder measure out of the box match ready! Since its creation this powder measure has been helping Silhouette shooters and Benchrest shooters win matches and set new records. It all started with the time proven accuracy and reliability of the original Model 3 Powder Measure. The Model 3BR Powder Measure utilizes all of the features of the original Model 3 and to that we added the conversion feature s that Benchrest shooters were looking for. It quickly became our most popular powder measure for two very good reasons . . . Its broad range of charging capacity and its performance record. The 3BR dispenses charges from 5-100 grains. You can order an optional 3BR Handgun Metering Chamber that dispenses from 0-10 grains if you are loading for handgun or small charges. A Cast mounting bracket is included.
