Check the listing for details. Rcbs Uniflow Powder Throw Bullet Separator. Condition: New. Listed at 9.99 USD. Rcbs Uniflow Powder Throw Bullet Separator. So this is for the Reloader out there. I’ve sized this specifically for an RCBS Uniflow. You put the filter on top, and if you use a kinetic bullet puller just pour the contents from separation through the filter. No more trying to pick out a projectile from the pile of powder, just dump and watch the powder fall through while the bullet stays! This comes especially handy if you made the wrong rounds and there’s a bit to separate. Stock photo, currently this listing is for the color of black.
