Just saw this. Haven't used BD much in the past, but picked up 5 lbs. last year when 2400 and W296 were hard to find.
Last fall I loaded 100 rounds .357 125 gr. JHP using magnum primers (Winchester) and 11.6 gr. of Blue Dot. Then I loaded 50 more rounds of the same combo using 12.6 gr. BD. Thought they'd be safe enough as they both were below starting load in at least one of my manuals.
None of these have been fired. What think you? Teardown???
If I shoot 'em, it'll be in either a 586 or a Blackhawk.
