Real-world commentary

JSB Match Diabolo has been the benchmark Czech pellet and slug maker since 1991, made by Schulz Diabolo in Bohumin under founder Josef Schulz, spanning the Match, Exact, Hades, and KnockOut slug lines across calibers from .177 to .35 and beyond. At IWA 2026 the company rolled out an all-new packaging and label design across its full catalog; the underlying products and part numbers are unchanged.
