I bought a mold recently that turned out to be a 9mm gc. Not a big deal as I have been wanting to load for a carbine I have and this might be nice for some high pressure loads. The mold is an RCBS 124 GC although it is not marked GC. I was looking around the net and can't seem to find anyplace that sells the gas checks. I know the general feeling is 9mm doesnt need to be gas checked but since this is what I have I may as well try it. If I can't find any can I have the mold modified to a PB? Anyone have any sources for 9mm GC's?
Thanks
