Thanks Doc,
Ladder test Retumbo 65 to 71gr loaded upView attachment 17870

Retumbo is the powder my last 264wm barrel prefered by a good margin.

But PLEASE, clean your barrel often! It will cause a carbon ring and hard carbon deposits in the bore. Use a borescope to verify.

Otherwise Retumbo will give great performance and accuracy.
 
Interesting result. Velocity is quite a bit higher than the QL prediction. Primers started to flatten a little at 69 and 69.5 everything else was good but decided to stop. And in the beginning i was hoping to get to 3100 anyway, so I will do some confirmation around 67. Elevation was pretty much the same from 66 to 68
