Perhaps if I were going up against something that could bite back I would pre-measure powder charges and the like. 30+ years of ML hunting and I still just carry my powder in a horn, with a measure in my shooting bag. My philosophy is don't take the shot unless I can make it count, and if that's the case there is no need for a quick follow-up shot. Manipulating a greased patch and round ball takes enough time as it is- what's a few more seconds to measure out a powder charge? Even still, I can reload for a second shot in about 30-40 seconds (a tad longer if I have to put a cap on the nipple rather than prime a pan from my horn) and I know inline guys with pre-loaded chargers who can't reload as fast. The trick is to store everything in the exact same spot each time and practice shooting and reloading without having to look at what you're doing (except to glance down to see when the measure is full). Just a system that works for me.
