If you have not tried it in loading 5.56 rounds, give it a try.
With 23.0 Grns, CCI 400 primers and a 69 MK bullet, it's the most accurate load I have tried.
Max load is 23.8 Grns. Some rifles like a heavier charge.
The standard deviation is fantastic.
It's a re introduced BR powder and really works great.
I have not tried it in other cartridges.
It also does not change pressure from 40 below zero to 140 plus.
Great for people who live in places like e where it can go from 30 below in the winter to 90 in the summer.
