Really cool to have...
Really cool to have that many rounds but it's a pain to load it unless you have the technique down. I only put 25 rounds of 2 3/4 through it and it only failed to feed 1 but I could have messed it up when inserting it. It is definitely not the most comfortable thing to hold if you are putting this on a bullpup shotgun. You have to chicken wing if you want to hold your hand comfortably. Honestly I just hip fired half of the rounds because it was more comfortable to press the drum mag into my thigh or hip and shoot it that way.
