WARNING: 
Micah –
Great powder for 130gr heavy bullets in 6.8 spc. Single digit SD in my testing. Works in many other cartridges too.
Jim –
I have loaded 130grn-170 bullets with this powder using mag primers and have some great results.
Bunco –
I’ve used several powders (ball, flake, etc.) through my RCBS powder measure, but this powder feeds like a hot knife through butter! Consistently throws the same weight time and again.
Sammy –
Using this powder for .223.
