Default Lead Backplates.

Well Scott, how about a run of these?

Would have to be at least an inch thick to ensure stiffness, a little
tin and antimony for strength, and no travel cuts, full size or tall only.
Embossed with the title "solo diver".

In recognition of his new "status" at rec scuba, I think you oughtta
give Greg the first perfected one.

if you had the lead backplate and the brass backplate if you ever ran out of
Barrett ammunittion you could melt them down and make your own

It would probably even prevent some people from going to the wrong
boat after the dive...

60.219 pounds would make a lot of bullets.
