I heartily second Joe Wood's earlier recommendation of Kirk Merrington, who is located in Kerrville, Texas. His business telephone is (830) 367-2937 and to contact him by email use kmerrington@yahoo.com. Mr. Merrington is a bench-trained gunmaker, and fortunately for me and my firearms, he performs all of my metal preparation and barrel work. He terms himself "The Barrel Man," and that he is and much more besides, and is clearly the very best I am aware of. I am a perfectionist and know where to obtain the best work, and Mr. Merrington does the finest barrel work and other professional work on firearms obtainable anywhere.
