If I understand you correctly, you mean that a "dog tooth" firing pin is one that is extra long or protrudes past the breech face after firing? Or that the firing pins are built into the hammer?

At any rate I was planning to pick up some S&B or PPU ammo anyways so I'll give it another test fire with that. I would suspect Hornady ammo is hotter, especially this being dangerous game ammo.

I'll give New England Custom Guns a call and see what they have to say.
