Charged launcher

I have a new idea it is called the charged launcher it uses 12 gauge (red ammo) and you have to charge it and it and it shoots a explosive round. The more you charge it the farther it goes and more damage.  15 times seconds charged iss the damage you will do. It will blow up in your face if you charge it to 20 seconds. Each time you shoot 5 second reaload and 2 shots per magazine with firepower, one without firepower. It  can only be found in the crismon ring club case 5 percent chance of spawning. This also slows you down and it has a very big aoe range.
