Never tried Retumbo in the 6.5 x 284, I have been using H4831SC and its accurate, but on the slow side of 2820 fps for accuracy. I have read that Retumbo is capable of 2950 fps roughly or more. I'm itching to try Retumbo, but H4831SC works and have about close to 7 pounds of it, enough to last the barrel.
What velocity are you getting with Retumbo?
I cannot recall the exact figure as the 6.5x284 was not my rifle, but a clients that I loaded for but it was 2900+ fps with the Berger 142 grain VLD Hunting BTHP.
And in the .25-06 boy it was 3150 fps with the 115 grain Nosler BT’s or as Guy Miner calls it “the Blue Cyclone!”
Alas Retumbo is about as common as a Leprechauns pot of gold these days so I use easier stuff to find like Ramshot Hunter or Magnum powders.
