I like AR Comp, but when it disappeared, I moved on to 8208, VV-540, & more recently StaBall Match.
I'm not going back at the current price of Alliant's powders & all the others do equally as well or better.

Now, lets don't get carried away. I don't know if any of those is "better". If it is, I'll buy it!!!! I find AR Comp to be some of the most consistent powder, that produces some very accurate/precise ammo. The nice thing about it, is I can drop the charges right from the powder measure and into the case. Saving tons of time, as I hate fn around with the tiny .223 rem case. Of the powders you list, which one works best with 69's and 77's. Thanks buddy..
