I’m always looking for the right P64 SG myself. I’d take any of the cartridges you mentioned. Hell, if I had the extra at the time I’d love a 30-06 or 270 FWT SG.
We'd probably all love the 30-06 or 270 fwt SG. Those seem to be pretty hard to find though. Those are the ones I'm holding out for. Just the right one will eventually come along.
