Haven't been loading it yet, but have done some looking. They say the burn rate is close to Varget. It was intended to be a temp insensitive version of Reloder 15, but everything indicates it is on the fast side of varget.

223 chamber or 5.56? What cases are you using and do you know the volume of your cases fired in your chamber.

Yea, 22.1 max list on alliants website, but the velocity was good, close to Rl-15

Its over max but 23gr Lc #41 77smk or cc at 2.26 from my 18" 1/8 Noveske rifle gas is 2710fps and 1/2-3/4moa.

I went with 24gr tac for my bulk blasting load to run on a progressive though.

Every gun is different. Your results won't necessarily match anyone else's.
