I have a pair of reproduction LeMatt's and would like to know if anyone cast for the shotgun barrel. I have been using a buck and ball of .62" round ball with 3 round balls of .32" with 35 gr FFFg Black. 9 rounds of .44 and 1 round of about 20 ga shotgun makes for a fun time at the range. It also makes the SASS shooters look when you place one on the loading table.
