this afternoon reloaded 100 rds of 41 215s with bluedot for my father/ son session tomorrow on his range.
like you, i got a deal on some bluedot and am using it up at a rapid rate. does good in my 41s and 44s. some flash. no prob in daylight. some residue. cleans up easily. can get some reasonably storng reloads with it.
check several manuals for recommended charges. all in all a good maggie load.
