Charles Isaac, I don't know of any source for the proper bullets to make 8X57 J, that would have to be a 318 round nose, I think close to 200gr, Closest thing is the .323 170RN, and the .320 softpoints made for 32 Winchester Special. A lot of people report good results with the .32 bullets. I haven't tried them yet, but I think they may have a feeding problem in the 88/05, since the shorter bullet lets the whole stack of cartridges shift to the front of the mag, then when they get too far forward, they all "nose dive" when you try to cycle the bolt. I had that with 165gr cast rn bullets. Of course, that couldn't happen with the original clip fed version.
