    Just got a can of this new powder. Kernels are surprisingly short - should meter nicely. Not too different than Varget, slightly plumper but not much longer.
    Can is labeled:
    RETUMBO
    MAGNUM RIFLE POWDER
    For those interested, here is the data on the label. Label says these are maximums.

    Cartridge Load Bullet Velocity
    7mm Rem Mag 68.0 175 Nos Part 2800
    7 STW 77.0 150 Barnes XFB 3036
    7mm Ultra M 94.0 160 Nos Part 3212
    .300 UltraM 100.5 180 SP SPBT 3300
    .30-378 WM 113.0 180 SP SPBT 3460

    Might be a little slow for my beloved .308 Winchester...
    Anybody shooting this powder?

    Where in the heck can you find this stuff? I've been looking for it for months now.

    Retumbo is a great powder. So far I used it in my 6.5 WSM and 300RUM. Its every bit as consistent as H1000 (velocity variation). The Hodgdon loading data is right on the money for the 300RUM when corrected for 30" barrel length. I've had good accuracy in both cartridges.
    This powder adds new potential for the overbore magnums. In fact, because of this powder, I am going to resurrect my 6.5 STW. I had problems with the slow ball powders(temperature sensitivity and velocity variation). I look forward to trying in my 22-284 with 80gr Starke bullets.
    You can get this powder at www.natchezzs.com 1 or 8 lbs. [​IMG]

    I think this powder (Retumbo) was designed to compete with Alliant's Reloader 25. I have heard that it burns much more evenly. Would also like to try a pound in a 300 Weatherby I have.

    Retumbo is the powder in the 6.5 WSM. I use it for 120 B, tips 130 Accubonds and Berger VLDs and 140 Bergers. I have tried R-25, R-22, Ramshot Magnum, MagPro, Win 780, VV N-560 and N-570. Only N-570 with the 140 and even 160 gr bullets will outperform Retumbo. N-570 is so coarse it is hard to even weigh to the 100th of a grain.

    I have used it in the the 300 Ultra and it is the top performer with 200 gr AB.

    How did you get to be a Moderator if you shoot .308? You belong on another Board like Accurate or Sniper or Benchrest. Long Range Hunter is for Eargersplitten Loudenboomers.

    What is Varget? It sounds like a disease to me. How does it help a long range hunter?

    I've been on the internet a while, but this is the greatest thread necromancy I've ever seen.
