Its one of the lower end powders and has a pretty big learning curve to it.
Its best if you have either a really tight fitting sabot, or you off set that and go with a heavy projectile.
Once you load the powder, you want to COMPRESS it. It will easily compress 1/2" and that makes a huge difference in how it groups. Don't compress it, forget any accuracy whatsoever.
After learning all the tricks, I could shoot some great groups with the powder. One year I had a little over 16lbs and loved the stuff. Super easy clean up, consistent, consistent FPS if you were consistent in your cleaning/loading practices.
