Just from personal experience I would stay away from Murray Charleton, told me my M29 was a piece of s**t and needed a new frame and everything warn out. Funny sent it to Gunnar and he said it was the best first model M29 he had ever seen and offered to buy it from me for a friend. No head space problems, no end shake, absolutely perfect timing. The reason I sent it to Charleton was to get a once over before giving it to my son, it had been sitting at the grandfathers farm for 30 years and it was willed to me when he passed away. Maybe seen 5 boxes of shells thru it at the most.
