I highly recommend Dave  Seedenburg for all of your artillery needs. His God given talents are truely remarkable. I have never seen machine work so precise and exacting. He made my C S  Parrott  barrel flawlessly. The rifling is very aggressive with a gain twist and lapped smooth with no tooling marks .The barrel has all the correct provenance and stampings just like  it came from Tredegar . I am already shredding the center of the bullseye. Dave is a very likeable man  and has good listening skills and integrity .I have found a good friend in Dave and will look forward to doing business with him and his company again.
