I have one in 6.5CM since Giraud does not sell the 6.5 for the Tri-way (I use the Giraud Tri-way in 223 and 308, mounted on a motor rather than using a drill). I have not been able to get the Trim-it II to work correctly. I had to adjust the cutting heads for overall case length post trim, but I have not been able to get the cutters to line up correctly so that the chamfer/deburr occurs uniformly around the case -- it is always slightly off so that the chamfer is not even.
I spent many hours trying to get it right, using their instructions and multiple youtube videos, and finally gave in and got a Giraud.
BTW, the Tri-ways were already set up correctly and I have not had to adjust them and they work great. Now they will be redundant given I have the main Giraud unit.
