I sell Hornady revolver balls mostly in packs of 5 boxes of 100 for $61 shipped by flat rate priority mail.
I will also combine shipping for more than 5 boxes.
I just sold my last 5 pack of .454 balls, but I have plenty of .451 balls right now.
My TFL classified ad:
I use the .451's in my Pietta 1858.
They are easier to ram especially if using the loading lever on the gun or if it's a 5.5" Sheriff model that has a shorter ram handle.
I expect to have more .454's in about one week.
Possibly sooner but the holiday may cause a delay.
Let me know if I can help you out.
