Bullet Dice Set (Now w/ d20)

I found the d6 and d8 from MiniHulkMechs and wanted the rest of the set for one of my party members. We play Bunkers & Badasses, and damage rolls can add up quickly dice wise. I took SAMMI spec models for a few different cartridges and added the appropriate prisms with numbers. I had to make them a little chunkier to make sure they rolled properly, but all the other dimensions should be accurate. The d20 was left out for now since I couldn't think of a good round to use for it. Seeing as it's used as a damage die too though, I'll probably make one eventually.

Edit: I used a 40mm HEDP grenade for the d20. the size is a little cumbersome, but it was as small as I could go and still get a decent roll. There are two versions of the die; both have an additional band towards the top to help distribute the weight. One is toothed to help it grip the felt top a little better and give a more definitive stop, though it does require supports. The other is chamfered to be printed without supports, but doesn't roll quite as well on felt.

The set:
d4 - .22 LR
d6 - 45 ACP
d8 - 50 AE
d10/% - .308 Win
d12 - 12 GA
d20 - 40mm HEDP
