Before the warning, I used Blue Dot in some of my 357 Magnum loads, 125gr.-162gr. jacketed and cast bullets, with no problems.
I liked the powder, with loads from 9gr to 10.5, which were not maximum, but gave a reasonable velocity and accuracy, and didn't leave much residue. The loads were bulkier than Bullseye, and, in my mind, reduced the danger of an undiscovered double charged case.
I was at the bottom of the can when the warning was issued, so I just disposed of the remainder, and didn't buy any more.
Reading what info I can find, I am not sure If Blue Dot is a good idea any more.
What have been your experiences, post-warning?
I use Unique and and have replaced the Blue Dot with 2400 for the time being, and don't feel underprivileged, but what would be a better replacement powder for the Blue Dot?
