Great to hear of your first results being so positive!!! Way to GO!!!
I loaded some .223 Remington cases with 55-gr JSPs w/ cannelure last night for a deputy buddy to shoot. And I used Varget, 26.0-gr IIRC and a CCI #41 primer and I used a Lee Factory Crimp to run the case mouth just barely inside the cannelure groove.
What I like about Varget (and other Hodgdon Extreme Powders) is that it is far more impervious to temperature extremes. Others powders can produce pressure variations, particlulary in ammo left for instance in very hot sun. Or some powders in frigid temps produce measureably less pressure which means those rounds that you carefully zeroed last summer when it was 85-degrees might possibly result in a missed shot when it's 15-degrees out. So Varget is a very good powder.
I have on hand maybe five powders I think are good for .223 (including H322, H335, BL-(C)2, AA2230 and Varget).
The only one I EVER bought an 8-lb jug of.... was Varget.
Have fun, be diligent, and relax. It isn't rocket science and is really very relaxing!!!!!!
