If your target is at 300 yards or less, I don't think you have to worry.
Temp Stability?

How did the shooting world ever get by before the so called temp insensitive powders?

In reply #4 above (thanks fruitnut), he shows at 500' elev, 90* 500 yards shot would be 28.4 inches low with 3213 velocity
move to 6000 feet elevation and lower temp to 50* 500 yard shot would be 29.6 low with 3113 velocity.
raise velocity to 3163 at 50* 500 yard shot would then be 28.2
So, if I was spotting for you and called the range at 500 yards and told you shot will be 28.2 inches low, NOT 29.6 inches. Could you possibly be able to hold a difference of 1.4 inches (in your scope) at 500 yards to make a difference? I don't think I could, so bottom line, I don't think it matters.
It seems we only worry when we handload our own ammo. When we shoot factory ammo, it seems we never worry about temp stability in powder that is loaded in the factory stuff. Not sure why, maybe it's because we have no control over the powder used in factory ammo. We just shoot it and kill stuff.
