Well I finally got a break in the weather to try my new mold a Saeco #645. My loads were 72gn OE 1.5 in twice fired Starline brass, not resized, .60 fiberwad compressed with a.45 compression die about 1/8". Tried 2 different alloys. COWW (10rnds) and Rotometals 20:1 (10rnds). The 20:1 was definitely the consistency winner on the targets. These were unsized out of the mold and SPG pan lubed, not quite round but big side was .460 low side .458. Mine dropped fairly consistently around 490gn with my alloy at 700. I was shooting the SR-1 target at 100 and got good groups 2" or so but with the 20:1 it was all vertical dispersion on both targets, 5 shots each with a bore pig pushed through after every shot. The COWW all held the 9&10 ring but were scattered, which could as well have been the shooter. Didn't get any target pics as when I was cleaning up knocked the container holding my bore pigs over and soaked the targets. Brent's bore pigs are awesome. What can I do about the vertical stringing? More crimp, less crimp, more powder compression, less powder compression. I could try some .30 wads which would be less compression. It was at least a great day to be out and fun was had.
