Bill K and Bayou City Boy,
I have his book here somewhere which I will have to read again as it has been some time since I read it. I knew about the Winchester and the Unertl scope. Thought I had read he also used a Remington 700 rifle later on ???
I had a person try to buy one of these scopes and to be honest I cannot remember if he said he was building a Hathcock Remington 700 imitation or maybe he just hinted at that. Been to long I am afraid.
The below link is an article which gives details of sniper weapons used during the Vietnam conflict. It also shows a Remington M40 topped with a Redfield 3-9x40 scope. As Bill and Bayou have said, not surprising on what was said to have been used.

This has turned out to be a very interesting post.
