Forum:I need help calculating how much my explosive shotgun does.

So I have an explosive shotgun. Its stats are as follows:

ZX10 Detonationg Shotgun

Damage: 19x7

Accuracy: 41.7

Fire Rate: 1.6

It also sports a high elemental effect chance & a 3x tech muliplyer if Im correct. Also my beserker adds another 15% damage.

So could some one crunch these numbers for me? I need to be able to know when the next shotgun I pick up with be better. Thanks.

BTW. If this thread is created wrong, dont blame me. Dr. F made a link for me that automatically makes my question the subject title up top or what ever.
