    I just started loading for this cartridge and found that after fire-forming my powder funnel hits the 40 degree shoulder before the mouth of the case contacts the interior of the funnel - resulting in powder spills each time. I'm using a cut off 218 bee case to bridge the gap but would like to just buy another funnel - if there's one out there to handle sharp shouldered cases.

    Thanks,
    Robin

    I tend to favor the Saturn aluminum powder funnels. Since the are caliber specific, they don't go down far enough to hit the shoulder.

    I've been using old (well over 10 years) RCBS and Lee funnels for this cartridge since 2008 with no issues. If I weren't inclined to buy one of the pricier options I'd trim one of the cheaper plastic funnels.
