I had two barrels rechambered to 308 Bellm by mike about 15 months ago. He stated about a month and it took a little over two months, no problem for me and excellent work. I believe Mike will "batch" his work, set up to do one thing like chamber work and then do all his chamber jobs. In this day and age it takes some efficiency to keep a shop going. You will be well satisfied with the work he does.
