I picked up one from China years ago. The old time Chinese seemed wild about them. all of there 7.65 Mauser/tokerov[sp] ammo is C-96 safe however is corrosive and neeeds cleaned up right away.
Cheep reloadable cases can be made from 5.56/223 cases. 1) full length size in mauser die, 2) hack off most of neck 3) Trim to length & ream neck to .308 or .311 [can be done in one step on a Forrester Trimmer] and reload. With a band saw and a drill powered trimmer I made about 200 unprimed cases an hour- in my haste i'd loose 5-10 in the trimming process. I always used military brass that the pimer crimp was removed from and had been reloaded 1 or 2 times.
There is very little rifleing in mine but Chinese [Norinco] shot 2-2 1/2 inches, the Russian not so well, worse than cast reloads about 6-8 inches at 100 feet.
In the era these were made, I belive the sights to be correct out to 1000 whatevers, as volly fire would be the norm, but I don't know if it would go through your coat at that distance??? A 1000 yards it only has 26.5 pounds of energy and mid range of over 3600 inches! and it got there 4 plus seconds after the rifle rounds, but you would be a part of the group action and close to the barn size target.
All and all a great gun to shoot and plink with. By the way, I used 223 strippers with 8 rounds in them to get by.
