You can only use one magazine at a time.....having 8 or more would be great in a war or protecting your property from Zombies but that's a lot to carry around if you're simply looking to shoot at the range
For the rifles I always found it easier to load the mags in the comfort of my home and then just bring the whole box to the range... it seems I am pretty damn close to the middle of what people admit to.....
Thanks all
