I am currently using a Sauer 202 375HH (but not a TD) on a regular basis every year for 4 years in Africa : Burkina Faso wthere the Sandwind Harmatan is almost constant and in the Central Rep of Africa that is similar to Cameroon. Never jammed.......but I used to clean my rifle every day. I have another barrel, 300 WM, but never brought it in Africa.
Oh,.....the first year...... I got jammed with the screw fixing the fore getting loose, a current issue if one doesn't think to use loctite to fasten the screw.
This Hatari is a beaut.......especially the chestnut wood. congratulations
