I recently read an article over on african hunter by John Millar who built himself a 4 Bore double building such a rifle has been on my mind for a number of years since I used to earn my living as a gunsmith. I have attempted to contact Mr. Millar through African hunter without reply.

If any of you may have an idea where I might find diemensional information about 4 bore or John if you watch this site please contact me.

thanks
