I have read that one should never pour powder directly into a warm rifle barrel because there just may be a spark waiting to cause some excitement. :bow: That makes sense to me, so when I am firing and then reloading, I always use a measure not my horn or flask. If I am firing, setting the gun down, walking downrange (actually up in my range) to check my target and then returning to the gun to reload, I quite often pour using the measure on my flask. I assume that to be safe if there is some time between the last shot and the pouring of powder. :hmm: If that is correct, and I might be wrong thinking it is, would I be safe reloading barrel one of a side by side shotgun using the flask measure shortly after firing side 2? Does that make sense?
