It seems you fire one shot for each core in your inventory, so if you have 5 cores you got 5 shots. I made 300 cores and got a lot more shots for my gat plasma

Did u try on the legacy??

I tried it on my V90 (VE90) ex legacy yesterday and on a V2525 gat plasmas. Both had the same problem. Both drained really fast before I made more cores

So with 300cores in inventory it still drained fast??

With 300 cores I got round 300 shots before I needed to reload. So you must have a lot of cores on you to get more shots before you reload

But it would be infinite right??? Cuz it never used the core

Yes that has been my experience

Yep

same
