Retumbo Smkeless Powder
Retumbo is my absolute most favorite gunpowder for the big magnums. I get extra velocity and great shot repeatability.

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!

Retumbo
Undoubtedly the best Magnum powder out there. Use I 7mm rem mag and 270 WSM with excellent accuracy and speeds.
