Both the Redding 3 and 3BR Powder Measures are very consistent and accurate with the powder charges that they throw. Many reloaders looking for the most consistent powder charges decide to install the Redding Powder Baffle. Powder baffles help to ensure that there is uniform pressure on the powder column in the rotor of the powder measure. This means that as the powder measure empties the same pressure is exerted on the powder column when the hopper is almost empty as when it was full. Notes: Helps maintain consistent powder pressure on measure's rotor for better charge uniformity
