I have had good luck with it loading for my 4 6.5 Grendels, a 6mmAR wildcat and a .223 18" JP. In those cartridges it gives me the best speeds. I worked up one .223 load with it; 26.5 grains with a 55gr Sierra BlitzKing that shoots really well.
NOTE: this load is safe in my rifle. All standard reloading practices should be followed with others loads. Start low and work up slowly.
