I had one of those years ago, but mine was cut to drop a .268" CB, which I then sized to .267" for my "as issued" M 96. Accuracy was 2 m.o.a. if I kept the velocity ~1,600 fps. Btw, Lee Precision had custom designed 6.5 moulds, both a single cavity and a 6 cavity version (group buy on the Boolits site) that were more reliably accurate than the LBT design. (The Lee looked like a smaller Lyman #311041.) Lastly, NOE made a similar mould which I ordered as a plain base for my M 96, but it wasn't quite as accurate as the Lee or LBT.
