Since you have had no responces I think no one sells the bullets you want. Get yourself a lee lead dipper, a 200 grn. Lee 30 cal mold a stainless cooking pot at a thrift store, a Coleman camp stove & a Lee custom sizeing die @ .301 dia. some plumber's lead & some 50/50 bar solder, mix to 1:15 Take all your casting stuff to a local park (in nice sunny weather) set up on a picnic table & cast away. run your new bullets through the Lee sizer & paper patch to .309". Load to aprox 2000 fps, shoot them & see what happens( smile)
