I own an M03 Arabesque. I have three barrels. A 375 H&H, 404 Jeffery, and a Match Grade .308 Winchester. All three barrels shoot a lot better than I do. I find the "return to zero" reliable at 100 yards. At 300 the scope takes a few click to get to zero. Action is extremely smooth. The safety is the best I've found. Tip of the day. When you go to set the barrel make sure you degrease the metal plate that the barrel sits on.

Only downside is that you have to use Mauser's , barrels, bolt faces, scope mounts and rings. The Mauser mounts are rock steady!

Hope you enjoy your M03. I plan to make a lot of room in my gun safe as I add new barrels!
