Wall mounted Chess Set?

I saw this guy that makes upright Chess Boards at the Home & Garden Show and thought it would be neat if he used Ammo as the Chess pieces. The million dollar question is which bullets would you use if you were the designer? Keep in mined both sides need to match in caliber size, but differ in color. Also there is a stability issue and of course the primers would have to be removed for safety.

K= 50BMG... Too big? make a bigger board..
Q= .45/70
B= .338 WinMag
K= .30/06
R= .243Win.
P= .223

Oh, They aren't "Castles" They're Rooks....

Yes, I've played on and off since 7th grade...

Pardon muwa Rooks lol, How about a 12ga. 3"mag. I do like the 50BMG for the king but your right it's just too dang big. Good choices though. How would you modify the frame? maybe use some old rifle stocks or barrels?

Well some of us do have that "culture" thing.. [Tooth] "Castles" I never...

I'm not sure about the 3" shell,, I don't think it would be "big" enough.. The Queen has all the power, But, She still Likes Her King "big"

Maybe something, Say "exotic" Like a .577 T-Rex, .50/120 Sharps, or a .460 Weatherby Mag.. I just thought of the .50BMG first, 'cause it's easy to get dummy rounds..

As far as the frame, I think stocks or barrels would have too much of an angle too them, Just wouldn't "look" right... Maybe inlays..

Q-375 H&H
K-300 Win Mag
B-.30-06
K-308 Win
R-.30-30
P-45ACP

The Queen is the most powerful piece. It should be the most powerful caliber.

OK, now how do we differentiate between black and white? Brass vs nickel cases?

The rook should be a wad cutter.

K=375 RUM
Q=338 win
B=30/06 spr
Kn=308 win
R=458 win
P=223 rem

And if using pistol ammo...
K=50 AE
Q=45 colt
B=9mm luger
Kn=357mag
R=45acp
P=22lr

I like where you all are going with this. Please continue.

I think the rooks should be 12 gauge 00 buck.

Bishops should be FMJ

King and Queen should be HP (kinda looks like crowns, right?)

Pawns RNL (or plated, it'd suck to get lead poisoning from your chess set)

Knights.... I dunno.

Great choices so far guys, I'm impressed we have so many Chess Fans here. Now instead of painting them Black or White how would you distinguish between the two sides?

steel case for black, nickel/aluminum for white?

I like foxtrots idea about the nickel plating.
