Had one back in the early 70s. It would shoot pretty accurately with 30/06 ammo. One of my Uncles brought it back from the war. Thankfully it was stolen out of my pickup while parked at highschool.
My brother has one that my grandfather brought back from WWII. He has shot it, and I think he reloads for it, but I'm not positive about the reloading part.
Feel like I just read an article in Handloader or some other shooting magazine about this cartridge. Essentially duplicated .308 Win/.303 Brit ballistics.
