Since hogdon doesnt' make anything themselves..they just buy it from someone else.....I have a hard time thinking the stuff is earth shattering. PLUS....they lose a bit of credibility when the proclaim that using the new powder in the 300 wby results in a whopping 3310 with A 150 GRAIN BULLET......WHOOOOOHOOOOO!
Personally I think we're seeing the marketing people telling us they have something really really new and it's probably a surplus that's been around for quite a while......or something that's been made by ADI (an Australian company) for a while..... (where they buy most their powder), or some other producer.

Let's see I am getting 3125 fps with a 300 gr Barnes X using H4350 in my 416 WBY. So maybe 100 fps more????
If they are the people here is an interesting story found by google search.......

I wonder if W780 is the powder that Winchester uses in the 458 win. mag. Safari load. If so it may be some really good powder, because it can propell a 500gr. Nosler Solid to an astonishing 2240 fps !!! That kind of a velocity from that little 458 win. mag. case with that large monolithic solid is IMPRESSIVE if it comes from a 24 inch barrel.
Some time ago I had a 458 win mag rifle and I wasn`t able to achive more than 2100 fps. with Barnes Solids in a 24 inch tube, without very difficult bolt lift. This maybe the powder of choice for that little 458.

I kind of doubt W780 is the factory powder for the 458 mag. Big bore, straight walled cartridges normally do best with slighty fast to mid-range burn rate powders such as BL-C2, 3031 or H322. W780 is claimed to be on the slower side.
Might be wrong though, wouldn`t be the 1st time :wink:
