I have seen some guys using toilet rings but they "stiffened" it up with paraffin. At one time or maybe even still now the rings were made in the same factory with most of the same components that Alox was made with. But with over 1,000 lbs. of lead to cast I am looking at all options. Will cast some of the "mini-ribbed" slugs and use some tumble lube reciepes also. Open to all ideas -- if they work for me or not. That's some of the fun about doing this reloading, casting thing. Also the flexabilty of it.
