Major, I've had great luck with Lodgewood.
Two Flints, thanks -- and thanks for keeping the faith -- and keeping the light on here over the years. I might have posted a photo here of me in my SSS ballcap on a plains game safari in Namibia back in 2007.
Kevin, I'm going back through the SORI files and will keep a special watch out for Fox Creek Kid's posts.
Prior to this one, I have had two of the Armi Sport Spencers in .56-50. The first had an issue with the tube mag latch, but the second ran fine. The first, I loaded with bullets cast from a mold I bought from Dakota Widowmaker. The second I shot with bullets from a similar mold modified by another fella here at CAS City, as DW was not making them at the time. I have a couple of dozen of those bullets left over -- from the modified Lee 515-450-grain mold. I wonder if anyone is still offering that modification.
When i get everything assembled, i will try some loads both with Swiss and Old Eynesford, which was not available last time I shot a Spencer.
