2-1/4" Zinc cannonballs
« on: March 31, 2024, 08:21:12 AM »
I have just received notice that the 2-1/4" round ball mould I had made is complete and should be shipped next week.  I talked Glenn of LEM moulds into making one last mould for us.  I asked this one be made a bit more robust than past moulds.



When it arrives I will forward it to RotoMetals and have them cast up some samples for me to evaluate and measure..  I will send at least one sample to Trey to test in his cannon.



I have tried to contact Jack at Hern Iron Works to get a sample of his barrel liner to test a ball in.  He hasn't got back to me yet.  When the mould gets here I will try to contact him again.



Rotometal is asking $8.99 for as cast, un finished 2.56" popcan round ball, $12.99 sanded and finished.



Using George's round ball weight calculator: http://gunneyg.info/html/ShotWeight.htm,  The popcan ball should weigh 2 1/8 lbs.



These balls at 2-1/4" should be right around 1.44 pounds.



I don't have any idea what they might cost. My guess is some where around $6-$7 each

Okay, Rotometal has these balls up on their website.

https://www.rotometals.com/zinc-cannon-ball-pop-can-mortar-2-219-for-2-steel-lined-bores/



$8.99 you clean, $12.99 cut and sanded.



If you have a cannon with a 2 1/4" steel liner like Hern uses the balls should fit your gun.  Buy one ball and roll check.

If you contact Rotometals be sure to tell Ryan thanks for his support.   

Also for any order over $149 shipping is free.
