Hellboy Big Baby Ammo

I've been working on a life sized replica of Hellboy's Big Baby (from Hellboy 2). Visit my build thread on theRPF if you want: http://www.therpf.com/f9/my-1st-prop-scratch-hellboys-big-baby-build-thread-179278/

I've 3D printed a lot of the parts, but to someone without a Big Baby, most of those parts are probably useless,except 1:

The life size, 2 Gauge, suck on this ammo from the movie!
Great model Kenzo!
