I have bunches of dive weights, (mostly used for doorstops, tie-downs and other things now that we're warm water pretty fish travel types). The more you dive, the longer you stay at it, the more that accumulates. Friends quit and give it to you, etc. When Gander Mountain decided to divorce from SCUBA, we bought it for 25¢ a pound. It does accumulate over the years.
Each and every weight is stamped (cheap die stamps from Harbor Freight) with metric and standard weight, also the Pounds were also stamped in decimal, ie: #3.75 and 3-3/4 and 1.7 (for metric). This makes it a lot easier to do the math while on the beach. We occasionally go for a thrash in the local pond with friends who are new divers.
As for a total? Help me do a story problem :doctor: with the math....
(112.76# of dive weights)
+
(At 230 grains of lead per cartridge, at 50 bullets per box, 10 per case... I have about 22 cases of .45 ACP ammunition)
+
(42 completely loaded magazines for her Glock, each which hold 33 rounds of 9mm ammunition at 124 grains each)
+
(and 1 9mm cartridge already up the pipe in the Glock 18)
=
____# of lead?
