Found among my late friend Zeke’s paraphernalia.
The three on the left are still intact, the three on the right had the paper crack and the powder spilled out.
The bullets have an OD of .577", are .965" long and weigh 32 grams, 1.129oz., approx. 500 grains.
I assume these are large caliber Minie Balls, Civil War era or later?
