Any experience with this stuff?

Found a guy with 2 lbs for a not bad price locally....

From what I've read seems to be a not bad powder.

https://www.vihtavuori.com/powder/n550-high-energy-powder/

The guy says that it work well in a 300 win mag with lighter bullets.

Bought a pack of berger 130 gr. 30 calibre bullets and wonder if it would work?
