First off, I'd like to say hello to everyone. I am new to the forum and happy to be a part of the discussion. I recently purchased a Sako, L61R, Mannlicher, carbine chambered for .375 H&H. Upon inspection I found that the magazine box was, well....deformed. Upon disassembly I found that the front of the box looked like an elf had taken a penning hammer to the inside. I assume this is the result of recoil pushing the rounds in the magazine forward. Also, the metal itself seems twisted as though someone didn't know how to reassemble the gun and just used brute force. The side of the magazine box is stamped "AIII". I had always thought that the AV was the beefed up magnum version of the AIII. Does anyone know if AIII magazine boxes were used on the AV actions? Also, where a guy might look for a replacement. I got a good deal on the rifle, so I' m not too heartbroken. I just want to restore the rifle to original condition and then of course shoot it. Thanks in advance for your help.
