I used one years ago for a .338-06. They are neat actions. Mine was stamped "Safari Arms" but they are the same action. I bought a Dumoulin action years later and they are exactly the same. The only thing I had done to the action was replace the bolt handle which wasn't necessary but I wanted something different. I found an old 1/2 octagon 1/2 round full integral rib guild barrel and had it re-bored.
My top caliber picks would be:
7X57
7X64
30-06
338-06
9.3X62
anyway here is the finished rifle.
IMO, they make a beautiful rifle.
