I went to the range last Wednesday to change some scopes and sight in the rifles so I drug my 4 frame along , Wanted to pattern it from the bench with slugs I cast from a mold I got from Bikerbeans a few months ago . I forgot the diameter but it's a 630 grain solid base he had cut for a 12 gauge . however it works fairly well sitting inside an SP-10 shotcup for my 10 gauge guns much like the Russian 10 gauge version of the Lyman 525 sabot slug I also have . Anyway I shot two 3 shot groups from the right barrel and two 3 shot groups from the left barrel all at 25 yards . I was pleased with the results .
First group right barrel
Second group right barrel ,
First group left barrel ,
Second group left barrel ,
