Surplus powder similar to Ramshot Tac available

[6mmNewB]

I bought some of the tac and for the price with shipping and hazmat included it's a great deal imo

Have you put it to use yet with a chronograph? Wondering how close to Ramshot Tac, Data is working in the real world? To state this differently, in your experience is this propellant a bit fast or slow or nearly identical to Tac?

Used at the range with some 95 Hornady SST, 28.5 grains was the ticket. 2780 fps. 24 barrel savage switchback.
