Gil. I have one of those FN Mausers, but in .270 Win. If yours is anywhere near as accutare as mine, I think you'll be very happy. I have/had one just like yours in 30-06 but the barrel was bad. Whoever had it before me shot corrosive ammo in it and did not clean the barrel properly.
A good friend of mine who was a hobby gunsmith replaced the barrel with a 1 in 12" twist .30 caliber barrel, chambered it to 30-06 and replace the somewhat beat up stock. So I had $100 in the gun and another $125 in gunsmithing and had one fine rifle. The stock got broken in a fall during a hunt so it now sits in a McMillam synthetic stock.
When you look at it closely, except for the bolt release and barrel contour, you have almost the exact same thing as a Browning Safari grade rifle. Not a bad place to be. As far as what I think of FN actions, every time I find a clean J.C. Higgins M50 at a gun show, I snap the darn things up. Most are scheduled for rebarreling into something I don't already have. Just have to wait for the money to have it done. So far, I've made up a 7x57, .380 Rem., and just has a .308 win. done. I'm thinking maybe a .338-06 might me the next project. Maybe another Whelen with the proper 1 in 12" twist in the barrel. Just have to scrounge up the cash.
