I have an M03 with a few barrels; 243win, 300wm and 7x64. For my use, I decided to go for their synthetic "Extreme" model, and so far I couldn't be happier. All of the barrels are very accurate, and don't need to be resighted when taken off and put back on. The decocker/"safety" takes a little getting used to, but I have come to the conclusion that I like it a lot better than the Blaser decocker/"safety" (I used to own a R93).

Feeding has been very reliable with all the calibers I have, and it will feed with no problems no matter how I hold the gun. Even upside down.

NitroX/John used it to shoot a moose when visiting Norway last fall, so maybe he can give you his impressions as well.

The only thing I might have done differently if getting a new one is get the light model, which saves a bit of weight.
