First off, if you are a sniper and need that many shots to hit your target, well, maybe you should just practice a little more at the range.
Second- Fromthe slim possibility of having to firing several times at several targets, a DM mag is the best way to go. You can carry a couple mags on your vest and have 20-30 rounds ready to go, just drop the empty mag and put in the loaded mag.
If I thought detachable mag was the best way to go I'd probably have the HS Precision conversion on the way.
It's more of a personal preferance than a need but I appreciate your concern.
