Made it to the range Thursday . Was able to get some quality groups with my circa 1891 Parker EH 10 gauge 2 frame with factory 28” CYL/IC barrels shooting the Russian knockoff for a 10 gauge of the Lyman sabot slug . It weighs about 620-630 grains . I also recently got a mold for the Lyman 20 gauge 350 grain sabot slug . I tried this one in my little circa 1928 Parker VHE 20 gauge 0 frame 28” M/F barrels . In once fired AA hulls they did pretty well in the CB knockoff wad . I wanna try some more . Also had my semi recently acquired 1968 Browning A-5 12 MAG with an also Belgium made 24” slug barrel . I shot factory in the Browning and it did exceptionally well at 25 and 50 yards shooting 3” Remington , Winchester and Feferal slugs . These were all the none premium stuff . While I was pretty satisfied with the whole thing I wanna try all three a couple more times .
