Dunno if it's true, but I read on a different forum that Hodgdon is phasing out IMR Enduron powders. I don't know why they'd do that unless it has to do with customs/shipping/supply chain/logistics issues. It's good, popular stuff

Is use it in my 40cal sml. I have a pound left so if I only use it for hunting, it will outlast me most likely. I built one for a fellow I hunt Eglin with so I'm trying to fix him up too. It is Said to be a perfect Varget replacement but Varget creates a fouling that builds up in these sml's, making loading difficult. Having the same burnrate as 4064. I ordered 3 pounds for testing. I could go with slower powders like RL16 but 115gr of it won't fit in Winmag brass as a charge holder. 83gr of 4166 fits perfectly and the necked cartridge negates the need for a loading funnel.
