Are you speaking of the Old White 1-3/4oz loads?
Those are the most efficient factory turkey loads ever put on the market.
If you can get some that don't suffer buffer leakage, I'd jump on them. I always get higher numbers out of those old shells vs the 3-2-6. Probably have nearly a case of them in my loading room, but will probably end up cutting them apart for the shot rather than shooting them
