Can anyone point me in the direction of some data for this combo? I did a little work and found a modest load that showed potential plus I use retumbo in my 25.06 and 300 ultra so it would be nice to streamline a little
 
Go to the reloading manual for Retumbo's maker ....is it Ramshot Powders?

The Ramshot company has a very good manual at its website (through the mail, also) and it is free
 
Hodgdon powder data

It is a hodgdon powder.

R#22 with a Fed 215 will get you 3600+ with a 100g pill, why throw away 200 fps?

My accuracy load was the Nosler Book's most accurate load.

Agreed the RL-22 is hard to beat in the 257Bee.
