I am having a .270 Mannlicher-Schoenauer carbine rebored to 9.3X62, and have agonized somewhat over accomodating the rotary magazine to the larger neck and bullet diameter case. However, the gunsmith tells me that he can handle it. If worse comes to worst, there is an Austrian firm which still manufactures parts for the original M-S. Since I already own two .35 Whelens and a .35 Brown Improved Whelen (long story), I didn't feel the need to convert to that caliber.

I also own rifles in 9.3X57, 9.3X64, 9.3X72R and 9.3X74R, so I thought I needed to round out the collection.
