Lyman 358156 & 35891 Chrono Results

[Rodfac]

I did some chronographing several months ago with a number of my revolvers & two of my favorite cast bullets: Lyman's, 358156GC LSWC & 35891 WC. Both were cast from 2:1 ratio, ACWW to Pb, sized to 0.358" with annealed Hornady GC's and lubed with 50-50 Alox-Beeswax. I thought the results might be of general interest to guys who don't have access to a Chronograph.

Best regards, Rod

Thanks for posting your results. I use the same load (6.0 gr. of Unique)under a 158 gr. SWC from an H&G #51 and average 1020 fps from my 4 3/4" Uberti's and 1200 fps from my 20" Rossi. It's my around-the-place-utility load.
