I know full moon clips are all the rage now but I would not turn my cylinders down to accept moon clips unless you are a competition shooter and every mili-second counts.

For the 45 acp cylinder. I would not "shave" the back off. I would have each chamber counter sunk the correct depth to accept the 45AR cart. That way if a case ruptures it is contained rather than blowing all over the place. Before you say how often does a case rupture? You wear eye protection don't you for just such a incident?

Just my 2 cents.
