I bought these heavy duty #5 containers on Feebay (item #262668632928) to shake my bullets in, and WOW are they HEAVY duty, and inexpensive! I bought 15 ($16.65 shipping free) initially to see how good they are (made in the U.S no less) but I'm sorry I didn't get 50 @ $37 with free shipping.
The chintzy look alike "standard" weight type you get bulk pickles or olives in at the markets only lasted me 6 or 7 shakes before cracking and I can eat only so many olives and pickles These are far stronger. Check them out.
