There are 'air efficient' and 'non air efficient' guns
Magfed in principle is limited in paint, and therefore does not have efficiency as it's main priority
Speedball has efficiency as a priority for some. EG a back player who is shooting pretty much constantly in a 5 minute game in support of the rest of his team wants a lot of paint and the air to shoot it. Efficiency makes his air last longer
A number of magfeds have old fashioned and inefficient internals. But there are also modern 'hi tech' ones such as the dam
