Background on new Hogdon powders.
As I understand it the story on the new Hogdon Leverrevolution and Superperformance powders ties to a Mr. Emery . He was previously in the employ of NASA in propellants for rockets. Mr. Emery, working for Hornady, has developed these new powders in cooperation with Hogdon to do exactly what Larry's M43 has shown. They are specially formulated to delay peak preasure in the preasure curve. This has enabled an increase in velocity while staying within normal preasure maximums.
It is the technology behind the Hornady Light and heavy Magnum and Leverevolution products.
So far I've been sitting on the sidelines as I haven't purchased any of the new powders yet. My health keeps me throttled back considerable, and now the heat here in Louisiana has been running mid 80's at night and at and over 100 in the day. Add in a good supply of mosquitos and you get the picture, so maybe in the fall, if I can get feeling better , I'll give some a try in my Marlins.
Great work Larry, I'm very interested in the heavy cast 30-30 testing as I have the RCBS 30-180 and like it's design very much. Also please give us some feedback useing 170gr. jacketed in the 30-30 with the LR powder.
Guzziac,
