Hey guys,
Anybody out there have a recipe for 7mm wsm with retumbo for a 100 gr varmint bullet?
Thanks

Retumbo would be way too slow for that combo. Notice how Hodgdon's data for a 140 with Retumbo is a 72 grain compressed load which peaks at only 54 ksi?

You'd get much higher velocities and use less powder if you just went with a medium burn rate powder instead.
