I went out to the range yesterday to test my first batch of cast bullets out of my ruger sbh. The accuracy was much better than i expected averaging between 1'' and 3'' groups at 20yrds.
My loads and grouping as follows. (12 rounds ea.)
800X
9.5gr with about a 3" group leading in cylinder not barrel
10gr with about a 3" group same as above
10.5gr 2" group same as above
11gr touch over 1" group cylinder leading and slight barrel leading
11.5gr easily 1" group same leading as 11gr
12gr 2" group major leading both cylinder and barrel
Unique
6.5gr 3" groups leading in cylinder not barrel
7gr 3" groups same as above
7.5gr 2" groups same as above
8gr 2" groups same as above
8.5gr just under 2" groups leading in cylinder slight barrel leading
9gr just over 1" groups leading in cylinder slight barrel leading
If you notice all loads had cylinder leading. The leading was a ring just infront of the case mouth. I dont know what is causing this? Other than that my SBH has always liked the warmer loads. Anyone have any ideas on how to prevent the cylinder leading?
