QL propellant burnt %

[TackDriver284]

I am pretty new to QL but learning, a thought came about when I was fiddling with QL. After selecting powders, you can see on the chart where it says Propellant burnt %. My question is, is it best to select a powder when the propellant burnt % is less than 99.8 %? Reason I asked is because the bullet is still being pushed out the barrel and still under force until it exits the muzzle. If the propellant is 100% burnt by the time the bullet exits the muzzle, will it have an effect on accuracy since its "free flying" down the barrel without any force behind it?

I don't think so. It's milliseconds, and still has a lot of pressure pushing behind it. The shock wave from the explosion is traveling faster than the bullet down the barrel and bouncing from end to end. Find that barrel time node and you may be at 100% burnt or 90%.

I look at powder burnt as efficiency... Closer to 100%, the less powder I'm wasting as muzzle flash.
