OMG no avoid large capacity magazines at all costs. They are evil, they make you want to pull the trigger and spray the target range with a flying cloud of toxic lead death. They cause more air pollution, ground pollution, and the horrible reinforcement of anti social behavior, like high fives and big grins.
Bricks and bricks of .22 are left as empty boxes and casings littering the ground. The barrel heats up and adds to climate warming, so does the vehicle you likely came in.
Get ten, enjoy, clean up after yourself, you will have a blast. Be safe out there.
BTW, let the kid at the next table try some. My son really liked the replica HK MP5. I forgot to bring the 10/22.
