Power residue

What would cause spent casings to come out with a sooty residue? I'm loading .243, 58gr Hornady V-Max, 41.0 gr of Varget (suggested minimum load). It shoots great but my fingers get very dirty from handling the brass.

Re: Power residue

Not enough pressure to expand the case to make a seal in the chamber by the brass...don't know the load but I'm bet'n it's on the minimum side.

Re: Power residue

yea, i gotta agree with Maub on this one, With the min loads the case does not opturate( expanding do to the pressure) in the chamber fast enough to keep the burning powder from leaving residue on the case, if the load is really accurate, and the powder meaters neatly for you, perhaps a mag primer might help,

Re: Power residue

that and/or your brass is work hardened and needs annealed.

Re: Power residue

Thanks for all of the feedback. I'll load some in the higher end of the recommended range. Some of my brass was bought second hand so I'm not sure how much it has been worked. I'll be sure to use some of my once fired stuff. Exactly how do you anneal the cases?
