Morning,
I been watching for gas check materiel other then amerisoft alum rolls.. finally found one that I really like.
Shim in a can!!! from MachineShop discount supply..
here is the Link https://www.msdiscounttool.com/catal...ucts_id=105470
I selected the .012 Shim in a can brass material 6" x 100" roll for 37.55.
I am very pleased.. it runs great in my freechek and my PatMarlin check maker nicely. they also carry the .015 or just about any other size you want.. Good product, good communication, good shipping, good deal!!!
give it a shot.
Marko
