Gewehr 71, Kar 71, Gewehr 71/84 (and if you count the variations including the Jaeger models). I have a Gewehr 71/84 and am working away at gather the supplies needed to reload for it as the bore is good condition as is the rest of the rifle.
As far as I have read, the .43 Mauser cartridge was decent for range and performance but it was found that with the single locking lug positioned on the right side of the rifle's action when the bolt is locked down hindered accuracy as the rifle "pulled" to the right when fired. The effect was worsened when the bayonet was mounted.
When I do take mine out to the range, I'll try to make a report about how she handled and how the round performed.
