The SBE will have problems cycling light loads, it should be o.k. with heavier loads, say 1 1/8 oz. of shot and a lot of powder, but the cheap shells you buy at discounters such as Wally World don't usually meet this criteria. It is a lot to ask of any gun to go from 3 1/2" mags to 2 3/4" field loads, and some do this better than others, but none are perfect.
