Duplicating 5.56 loads with Accurate 2230

[ColoradoShooter77]

Accurate powder has 5.56 data on their site. The 5.56 data goes all the way up to 26.3 grains on a 55 grain FMJ.

This is for an AR-15 5.56 chamber.

I've loaded 20 rounds at 25.3 to try it out. This is .2 grains above the commercial maximum.

I'm thinking this load should work very nicely.

What is the velocity you seek?

Wish I could find some 2230!

Out of my 16" barrel, I'll take all the velocity I can get. I'd like to be over 3000 fps.

This is powder that I bought 5 years ago and have barely tapped into it. I predicted there might be a powder shortage in the future, lol.

I also have 8 lbs of 8208 and 4895 on hand, those are still pretty hard to find too.

I load 24.5 grains of AA2230 with 55 gran bullets. In my 16" M4gery, I get 2960-3000 fps.

In all of my AR-15s except a Colt Match Target with a 5.56 NATO chamber, I begin to see loose primer pocket after four to six rounds with 24.5 grains of AA2230. Some of these rifles have Wylde chambers.

Routinely, the Colt gives velocities 100-200 fps less than other rifles with 20" barrels and the same ammunition.

Interestingly, the M4gery gets 3100 fps with Federal XM193 ammunition.

Hope this helps.
