My Bullet offers you custom engraving of your choice on 50 caliber bullets. They give you the option of single or double sided engraving, 16 characters per line. That should be enough room to mark commemorate whomever you choose on either a brass or silver bullet. I guess the silver are for those with severe werewolf fears.

Now this shotgun shell may not actually be live ammo, but no one else knows that. As long as you are putting with the plastic end as you would normally then no one will care. But start putting with the blasting cap end and you may get some very scared looks in your foursome.

Biting the bullet has never been so tasty. Instead of some nasty metallic taste these will give you chocolaty goodness. Each box is a miniature model of a real ammunition case that can be used for all sorts of purposes even when all those chocolate bullets are spent. Twenty rounds of 50 caliber bullets in each box.
