Collectors in Stoneham had some of this awhile back, don't know if
they still do. Might give them a call.
Best bet is to try to find some vendor that sells the 50 round
boxes of it, as it typically is a better deal.
If you're pigeonholed another good load is the Rem Golden Sabre
230 gr 45 ACP load It does excellent in gel tests and the like,
and is probably more readily available in MA. It will also feed in
the majority of handguns out there- if your handgun doesn't work
with that load then it's broken and needs service.
