I have no personal experience with Blue Dot in rifle loads.....nor do I have a dog in that fight.....my reasoning is simply that if the manufacturer (Alliant) doesn't recommend it then I don't use it!
I'm not sure if Al Gore invented the internet.....but of this I am sure....the internet has invented a helluva lot of experts and some are truly worth listening to.....but sorting them all out is beyond me so I confine myself to published loads from the manufacturers and those with pressure testing equipment such as Hornady et al.....
So far I have all my fingers, both my eyes, and haven't blown up a gun. It's a lot more fun that way.
