Power Pro 300-MP powder

Anyone have some experience with this powder? Thoughts? Thinking of trying it with 357 and 44 mag revolver loads. Thought it should give good results with GNR cartridges in a Contender.

I’ve used it in both my 44 mag and 480 Ruger. Seems just a tad slower than H110/296. Works nicely in the 44 and really well in the 480. It’s my go to powder in the latter nowadays. Haven’t tried it in any GNR chamberings tho.
