Well I cast for my dad, myself and my brother Ray. Two coffee cans sounds like a lot but when I load I fill up two 30 cal cans.
I have these 4*6 thick plastic zip locks and bag the loaded rounds 50 per bag. Two bags per row and between 400 and 500 per can.
On bigger rounds like 38/40,44/40, 45 colt I can only fit 300 per can.
On smaller rounds like 9x18, 22 TCM I can fit almost 800 to 1000
