Doug, I am not a airgun expert, but do have a lot of experience in the pro side of serious PB competition. “STD” can only be of any value if your projectiles be it pellets or bullets have a consistent coefficient. Meaning, weight and shape, so to get a good “STD” with an air rifle I would weigh my pellets and definitely use a quality match grade version. That would show if your gun is giving a good or bad velocity spread aka “STD”. I have found a big deviation in pellet coefficients by just weighing them, it was surprising how much they could vary. Hope this helps brother.    Dale
