This is a sperical powder. It meters great. You can fit more than you will ever need in a case, making it somewhat dangerous if you overcharge on accident.
In the range of powders that can be used for 5.56 "normally" this is a medium burn rate powder, while Accurate 2200 would be on the very fast end of spectrum and Accurate 2520 would be toward the slow end. Accurate 2230 and Accurate 2460 are very similar, except 2460 takes about ~.5 more grains to get similar velocity. It could be argued that Accurate 2230 is not necessary at all and you could just use Accurate 2460 for every application from 50 grain to 77 grain instead. There is some validity to that argument.
Being a sphereical powder, it is very easy and consistent to meter. Very easy handling powder if you want to just mass produce ammo, this is great.
It is also a reasonable price powder and readily available.
Accurate 2230 is a very high performance powder, as you can see below. It offers some of the highest velocities available for loads we would call 50-75 grain. A really good, versatile powder you can't go wrong with in 5.56. Buy it with confidence.
