CLIP VS MAGAZINE....."magazine" is a container in which ammunition is stored, whilst a "clip" is a small piece of metal which holds rounds in place whilst outside the magazine.  Sorry but even in SW this annoys me lol.

I just had a startling revelation (thank you chocolate )
For a weapon to ......erh....."shoot".....kablooey...., regardless whether it be firing bullets, plasma, lasers, the weapon has to have a source of energy.
A star fighter's lasers use a battery *X-Wing*(must be huge) energy collected from solar energy cells *Tie fighter* (cells on the wings).
A capital ship uses fuel to fire its huge cannons, I don't remember the exact number, but a Republic Capital Ship's main cannons (Imperial Star Destroyer, as I'm sure most of us know) use several million  gallons of fuel in one minute during a fight.
But a soldier can't carry around huge batteries or millions of gallons of fuel to power their weapons. So what do they use instead? Small light weight cannisters that contain the ammunition needed to power their weapons for a reasonable amount of shots, power packs, ammunition cells, call them what you will they........ hang on I just realised, er where is it? A HA!!!
"Common blaster weapons use high-energy gas as ammunition, activated by a power cell and converted into plasma. The plasma is released from a magnetic bottle effect to fire through collimating components as a coherent energy bolt."
There is more but it doesn't regard the ammunition, mainly range, precision since that's not what we are discussing.
But see what I am getting at? Every weapon uses ammunition, the smaller ones need to have fresh ammunition loaded into them after a number of shots are fired.

So there should be reloading in FS because it's in the rest of the Star Wars universe, just because we don't see it all the time in the movies, it still happens.
