Add IMR4451 to the possibilities. I've been switching all my former H4350 loads over to 4451 for a while now, and so far it's worked just as well in every load.
Thanks for the report. I'm about out of H4350 so I'll give 4451 a try.
I sure wish the new Enduron powders were priced like the other IMR/Hodg powders.
A bird in the hand I guess......
