Use this jig with an affordable Bead Buddy Hole Punch to center your holes in your breech face dimes every time. I had trouble getting my holes drilled in the center and I wanted to improve quality so I made this jig for use with a BBHP. After doing a hundred or so, my fingers hurt from twisting the bars, so I made handle covers too. Use the covers to spread the force out over a greater surface area and save your fingers.
