Long story short I appeared to have lost my reloading info and cannot remember which of these powders I reloaded with. I know I've used both for this gun but don't remember which was more accurate. Planning on shooting through my chrono to see what speeds I am getting with what I have left for a better indicator. Which do you prefer out of the two? accuracy is number one goal speed is number two. My current load is getting me just barely over 1/2 moa at 100 yards out of my vanguard s2 wish I could remember what is in it!
