Rusty
Actually after my first 2 body shots on the bull,when I reloaded I dropped those 2 cases on purpose, for a quicker reload, so I could follow up with more body shots,as the first shot stopped him in his tracks for just a second or two. He then spun around and came for us. He went a short distance and fell down [broken leg]. As he got back up I brained him, and he went right down. I did pocket that case on the one bbl reload, then ran up and from poing blank [4 feet or so] fired one round kneeling [to get the right angle] into the back of the head. Did a single bbl reload, dropping the case on purpose, then firing a second shot int the back of the head, then doing another single bbl reload I dropped that case on purpose as well. I did pick them up before I got up however. I then later recovered the first two cases I dropped.
So I have dropped a few cases when reloading my doubles but it is always on purpose.

I will add this:
I think the most important factor in getting a quick reload with a double is where you have the extra rounds, not whether you have an extractor or an ejector gun. I carry rounds on the buttstock of the gun, and when in a hurry reload from the buttstock carrier. I replace rounds in the buttstock carrier from my belt as soon as possible.
