There is not a whole lot of Boxer primed 7.5 Swiss cases out there. I have a small stash and you ain't getting any! I almost bet the ammo you are getting will be surplus Swiss G11 stuff. It's good ammo, but of course it is Berdan primed. But it is funny you should be talking about a Jap Arisaka. I ordered both a Swiss K31 and a Type 99 Jap Arisaka about the same time. When I got them in I took them both to the range the same time for first firing. All my life I heard about that vaunted Swiss accuracy, both in their watches and their guns. The Jap Arisaka actually was a bit more accurate than the Swiss K31, even though the K31 looked like it was in much better condition.
