generally speaking, the 8.15x46r was a target rifle cartridge used in many german/swiss single shot offhand target rifles.  It was also chambered in some light weight stalking (hunting) rifles.  I have also seen it in a few fairly light weight single shot early bolt actions in both early Mauser and early Mannlicher actions.  I know that some of the early bolt actions were used in schuetzen type offhand matches in Europe and they may have also had military target rifle matches using the 8.15x46r cartridge.
  If your rifle is checked out as safe it should be OK for standard target loads. 
The 8.15 is often thought of as a metric version of the .32-40, and 8.15 cases can be made form the same 30-30 Win family cases, with suitable modifications and fire forming. Buffalo Arms sells 8.15 brass that is made from 30-30. 
At least in cast bullet low-pressure target loads the loading data is pretty much transferable.  With your bolt action rifle the chamber may vary a little from standard. If you really want to maximize the accuracy potential, a careful check of bore-groove and twist would be in order; as would a chamber cast to get the correct case length and throat configuration for bullet selection.

Hello
I just returned from the range a few minutes ago shooting 8.15x46r. It is my favorite round. I have been shooting German schuetzen & stalking rifles chambered for 8.15x46r for 35 years. My favorite load is 13.4 gr IMR4227, large pistol primers, RWS brass. I use a 165gr stop ring bullet cast 25 to 1 or a 180 gr stop ring bullet cast 25 to 1 lubed with liquid alox. The 165 gr mold is still available from NEI, I'm not sure about the 180 gr pointed bullet. All of my rifles are falling block single shots chambered for a stop ring bullet I don't know if a bolt action in this caliber was chambered to use a stop ring bullet. From my experience the rifles designed to use a stop ring bullet won't shoot a breach seated bullet very well. This is a mild target load. Good luck, you will like this round for target use. I haven't hunted deer for several years, when I did, I used a 8.15x46r stalking rifle with a 185 gr gas checked bullet. I was very careful to get close & take good aim, never lost a wounded animal.

accurate molds has a modern design stop ring

And their system lets you order and vary the dimensions a little bit to adjust to your own rifles bore groove and throating how the throat is cut.
Some rifles designed for "stop ring" bullets may need to have cases shortened sightly to seat the loaded round without jamming the leading edge of the stop ring into the leade and making for difficult chambering.   
Some of our ASSRA shooters simply breech seat the standard tapered or cylindrical into the rifling and use their 8.15x46r rifles just like any other target single shot on the line.
