Tony, very nice Brazilian mauser. I've been looking for one of the unissued pieces for a long time. I've found several that have been cut down and one that was missing a bolt but otherwise untoudhed. All of the cut downs as well as the complete (now) rifle have indenticle chambers. It is impossible to tell which piece of brass comes from which rifle. even the primer indentations are so close that I couldn't tell you for sure. By the way, with proper handloads, 140grain spitzer bullets at appx 2900fps from the 29 in bbl they will shoot under 1moa. If you guys come accross a sporterised one, snap it up, they are dreams to shoot and the craftsmanship is phenomenal. bearhunter
