The 'Lighter' Side Of The Force
I'm not calling you out or anything, but there's lots of backstory going all the way back to a new hope that say blasters aren't lasers, they actually fire charged particle bolts. And you do have to reload at some point, might not be in the movies, but it's all over the books, legends and canon. It's probably a battery pack combined with a supply of some kind of gas for reaction mass instead of a magazine. All kinds of things are possible if you can manipulate magnetic fields the right way.
The Tusken raiders fire at anakins pod racer with a ballistic weapon during the pod race in episode 1. You can hear the bullet ricochet on the racer. But let's face it, if in nowadays battle you can choose between a antique front loaded musket or a high powered HK416... well, do the math.
