Don't see any reason why tapping wouldn't work. I've just done the drop tube thing. Fiver (aka the President of the Barbara Roufs fan club. Google her NHRA photos, put on eye protection first. It's all rated "G") is not too far off on how long it takes to load. I have figured out to employ my 550 to reduce the number of times the case has to be handled, I have it down to three. Then it only takes a little under 2 hours. For some they like to use over primer wads, under powder wads, lube cookies, raisins, (just seeing if you are still awake), which in turn increase the time up another hour and a half. I can load 60 rounds for a match in less than 90 min from an unprimed case to in the box.
