just ordered one of the above, a 525 grain slug.
any thoughts as to powder and amount, and wad used? these are for 12guage.
if this is for the lyman clone the best wads to use are the old WWA12 wads either red or white depending on columb height required, these wads are obsolete but still floating around if you can find them. As far a powder I've had good results with 32 grs of Herco, .Note these slugs perform better with the bases filled some guys use hot glue I've elected to use wax (cheaper and easy to apply). Crimped hulls worked better than rolled crimps for me also.
Good luck these are a great slug

plus a bit thicker skirt than the standard one, helps with deformation.
I’ve heard tell of those Slovenian moulds being seized by customs. Was a thread on the AR Fifteen forums.
