Hand-Loaded Means Hand-Loaded
One veteran, one bench, and a loading standard most factories would call excessive.

The name is a promise
“Teufel Hunden” is the old Marine nickname: Devil Dogs. Teufel Hunden Ammo Manufacturing is led by Paul Merioles: a believer in Christ, Marine Corps and Army National Guard veteran, and retired educator. Everything that leaves the bench carries that heritage: disciplined, precise, and accountable to the person whose name is on the box.
THAM specializes in the .41 Great Lakes cartridge, loading it to a standard built for hunters who take ethical harvesting seriously.
The THAM standard
Six controls on every round
Hand-Loaded Precision
Every round is individually hand-loaded, measured, and checked for consistency. Nothing runs on autopilot.
±0.02 Grain Charges
Multiple Supertricklers and AutoTrickler dispensers hold every powder charge inside a 0.02 grain window.
Case Conversion
Every .30-06 case is converted to .41 Great Lakes length, trimmed, and verified for uniformity.
Mitutoyo-Measured
Cases are measured with Mitutoyo calipers and trimmed to within 0.005″ to 0.001″ of spec.
Direct Consultation
Paul works with you one-on-one to match the right load to your rifle and your hunt.

The cartridge
Why the .41 Great Lakes
The .41 Great Lakes has earned its place in the straight-wall community fast: ballistics that outrun the .450 Bushmaster class without the bone-crushing recoil. For hunters in straight-wall-restricted states, it delivers flatter trajectories, serious retained energy, and quick, ethical kills.
Recovered bullets like this one are the point: full, even expansion that transfers energy where it belongs.
