I have an original 73 made in 1886 and while I haven't had a 66, the action is mostly the same except for the brass. I am not sure how much difference you would notice between the two but you have to remember that these guns by design were made to handle BP loads. They use a toggle link system to lock up the bolt and this system is not nearly as strong as a 92 action. I have done some gunsmithing on them and from what I have learned that if you have any problem from hot loads the toggle link and its posts will probably cause slack in the headspace of either gun if shot enough with 'Hot' loads. I love the 18766s & 1873s but if you if you just want to shoot a lot of full power loads I would suggest getting a 1892 which is much stronger by design.
