I'll play with Retumbo soon in a couple of my rifles and I do expect at least slightly better results as it isn't a revision of an older powder like some of the older Hodgdon flavors.
You don't know what you are talking about. The following Hodgdon powders are made by ADI in Australia with special technology not well known to others. Temperature information comes from ADI not Hodgdon .
H4227
H4895
H4198
VARGET
H4350
H50BMG
H4831
H4831SC
H1000
RETUMBO
H322
Benchmark

So they all have the same technology as Varget .
Wether any figure is correct or not these powders are proven to have less temp sensitivity than others on the market .

    I have some RL17 for my 6.5x55 swede and I can Definitely say it is temp sensitive. I have to admit for fair weather stuff it can be pretty nice though. It really just depends on what you are doing.

    The cooler test is a "real world" proven method.. if u think 60 fps variant in a load is good then i dont know what to tell u.. thats between 8-10 inches of error at 1k not counting human.. i would never be happy with any load that has a 60fps swing... i dont settle for anything over 18fps swing
    ... thats why ibuse hodgden powders.. they work.. i think.somethings just wrong.with the.load ur using.. just cus its a half minute load doesnt meam its the best load..

    I've seen 100 fps change with THE SAME BOX of 25 WSSM'S loaded with H4895;
    YOU do not know what you are talking about. I shoot over an Oehler 35p chrono.

    The cooler method doesn't take into account the changes in barrel stiffness or dimension when the temp. changes. I'm killing to 600 yards offhand with my 300 win; good enough for me.

    Maybe being shakey makes the load more accurate barrel stiffness has nothing to do with the powder itself myfriend.. if barrel stiffness was such a huge deal then no powder would work well in diffferent temp enviornments.. just my 2 cents i guess.. all i know is a shoot a hell of a long way sometimes in 5 degree weather and my velocities are damn near identical with my 90 degree shootin..

    I could have a more constructive conversation with a deaf mute than we are having here. Ii've seen a certain amount of vel. spread with ALL powders. Good day.
