Yes, I had a tin or two of the 1950's 196gr Yugo, with strippers, too. You couldn't give it away back a few years ago. Most of it I pulled, reduced the charge and fired off in the Egyptian.
If you really have a tough time finding it, bring your rifle(s) down and we can load up some and shoot 100 meters onsite. I have some tracers, too, but I don't know if they'll light off enough at 100 meters to even notice. I'd love that they are the multi-colored range indicating tracers, but I don't want to set the woods afire to find out.
I have ample reloads, plenty of .323" bullets, but very few empties, so bring whatever brass you have (even .217" berdan-primed brass and steel).
With your bolter anything from 125gr to 220 grain should work, just as long as they make it out the barrel! I'd think a 98 would be a great cast bullet shooter and you can shoot all day with some moderate loads. I've always entertained buying a Portuguese Mauser (Model 1904/M39) for cast bullets...
No molds here for 8mm, but there is a shop across the state that carries the Saeco 190gr LRNGC bullet.
