A custom reloading block that includes a powder funnel. Used for preloading powder vials, like are used for smokeless muzzleloaders, or any other reloader who wants to store pre-weighted charges of powder. The powder funnel is integrated into a slide frame that fits into the side rails, with a small little pip printed in so it will lightly (very lightly) snap into place perfectly aligned with the vial spot. I made the funnel tall enough to slide over with the caps on, and made the funnel hole very large while still allowing room for small misalignment without spilling powder. I hate having to tap funnels to get powder through a narrow opening…
Beware: there are different sizes of vials out there so check your dimensions before printing to make sure this will work with yours. The vials I use are from Arrowhead and measure 0.6" OD at the base and are 2.350" tall with the caps on.
