46T maybe 50T?
The issue or limiting factor is not the cogset. The limiting factor is ground clearance for the RD. On
10-speed 406, you want something along the lines of Deore M6000 which is rated to 42t. That's what I run on my 406er. Here it is...

The other GS alternative is to jump to
11-speed with this job rated for 46t.
