    Reloading .204 diy powder funnel and case trimmer

    All,

    Well I have tried out my DIY case trimmer which started off life as a .22/250 case trimmer. Paddy machined it down to the correct dia and by careful use of an oil stone I reduced the length down to obtain the correct Case length. I note the comments about the diameter and have used it to trim 50 cases and they all look and measure fine. So thats a result, however am awaiting delvery of Lee easy case trimmer.

    I have a standard Lee powder funnel which is not ideal however I had a bit of an experiment and realised that a .17 HMR case is the ideal size to fit inside the neck of a .204 case.

    A quick trip to a local cook shop sourced a small plastic funnel of correct dimensions, I cut the base of an .17 HMR case, chamfered the inside and fitted to the inside of the funnel, v snug but aided by some hot water treatment. So now have a custom made .204 powder funnel for a princely 1.

    Used it last night to load 20 rounds and it worked a dream, no issues with static.

    Only issue is that Reloader 10 sometimes does not dispense correctly when using a Lee powder dispensor. However easy to feel iffy charges and I weighed them all and they were spot on just now discard any charge when there is a sticky feel. I drop charge staight into case via funnel and then reload.

    So well on the road to getting the .204 sorted now just have to get out with it.

    Nice work.
    How far off were your powder charges?
    And did you weigh your bullets and brass as well?? ~Muir

    Muir,

    Not quite got to that stage yet however was not impressed by the quality of Hornady new .204 brass.

    I have a set of analytical scales so will do so and post.

    Don't bother. The point I was trying to make is that weighing powder to an exactitude suddenly seems pointless when the bullets are of different weights and the brass different volumes. I weighed some 168 grain Sierra Match King bullets this past weekend. A grain and some variance. They still shot bug holes from my 308.~Muir
