Awesome for Large Magnum
Perfect for my savage 110 long range hunter chambered in 338 LM. 87.5 gr behind a 300 gr A-Tip yields a .6 MOA.

Best slower burn rate powder I’ve used
This is by far the best powder in my .300 Norma improved. Might as well be fairy dust but if you can get some it’s going to work well in big .30s for sure. Very temp stable and very consistent ES. Hoping to find some more when I can!

One hole groups with multiple rifles
Retumbo is the unicorn of powders, works well in several 28 Noslers, a 300 Win mag, and 6.5 SAUM I’ve built. 4 rifles that I own shoot one hole groups at great velocity with this powder.
