I have acquired both an M03 in 7x64 Brenneke and a Mauser Magnum in .416 Rigby. Suffice it to say the Mauser Magnum is everything one might expect in a rifle of that price range and mine is superbly made and functions without flaw. Regarding the Mauser M03, I purchased with the intent of possessing a flexible rifle that was easily taken down, packed and permitted the change over of calibers. In the time I write this I can convert the M03 from .222 Remington to .458 Lott by simply changing the bolt head, detachable magazine and barrel (optics must be removed as well). I must admit I was not sure I would like the rifle as I usually shy away from the latest rifle models, however after using it in the field and traveling with it I am very impressed with the features, construction, accuracy (which is first rate) and the scope mounting system (one of the M03's best features as mine provides a 100% repeatable zero when the scope is removed). The rifle (as I understand it, is made by Blaser) and it employes their know how on rifle take down systems, however I much prefer it over their R-93 series (head and shoulders prefer it). Much has been made of the safety/cocking system and I found it took a bit of getting used to but well worth it considering the measure of safety it provides when hunting in a group or stalking. It is not an inexpensive rifle and my take on it is that if you buy the M03 it is with the intention of aquiring multiple calibers for a wide range of hunting, if you purchase it for just one caliber you still have a great firearm but are largely missing the point on its purpose of design. Of the post-war Mauser offerings I would have to state it is the best of the bunch.
