On the 1700, 1710 and 1712 rifles, there are no interchangeable cams on the trigger. It is a single stage or a two stage period, you can convert from one to the other by changing the actual trigger lever. In the two stage triggers the amount of pull can be adjusted for each stage. The trigger with the adjustable cam, and all the other bells and whitle is the model 5018 or 5020 which is used in the 54.18 MSR and the 1808 MSR, and several other fancy target rifles.

I guess I got it wrong, because I was repeating a story told by Neil Stepp. He said there were two versions of a "cam" on the 1712 trigger. I believed that this change in design changed the faction of balance between the stages. He said the 2 stage was common in europe, and about the time they started importing them in the US, Anschutz changed the geometry. This wouldn't be the first time I got something wrong, but that was my understanding. Again I am not an expert in the area, but I knew about the 5018/5020 story, and I don't think I am getting it mixed up. Maybe it was the geometry of the trigger lever, and Neil just said "cam"? I appreciate the correction. Thanks.

You remember what Neil said correctly. He said that the second version increased the difference in pull weight between the first and second stages because many users reported pulling through the second stage because of the small amount of additional weight in it.

Properly adjusted two stage triggers take up much of the sear engagement in the first stage so that there is comparatively less to be taken up in the second stage than a typical single stage trigger. They also tend to have more total sear engagement than a typical single stage trigger which keeps the rifle safe when loading a round.

Mausers have two stage triggers. They are the largest production volume bolt action rifle in history....
