@308mate I have a ODL suppressor now on my 30-30, I emailed Bert about this subject but haven't heard back. What's the reason to not use casts, because you can't clean? Do lead casts leave a heap of residue in the suppressor? I used casts when I had my DPT, didn't notice any residue but then I didn't shoot a lot of them before getting ODL suppressor.
