H1000 or Retumbo ?? 280 ackley

In my 280 ackley shooting 162 A-Max. I have tried h4831 sc. It was really consistent shot really good under 1/2" with 56g. @2750fps. any more and the primers would flaten. I tried 56.5g of R-22 @. It shot almost as good under 3/4". About the same speed any more and it would flaten primers.I am thinking of trying H1000 or Retumbo. Do you think I could get a little more velocity with them, Just can make up my mind what to try next.

    I've heard that your 280 Ackley has about the same power as my 7mm saum. I'm getting good results from 65 grains of Accurate Magpro. Over 3000 fps. with 160AB

    H 1000 has always worked well for me, very temp stable but not extra fast velocity.

    Ramshot Magnum provides the top velocities in both of my short mags...might work for you.
    The Ramshot website lists a top load of 60.3 grains for a 280 Rem with 162 Hornaday: 2797 fps.
    You could beat that with the Ackley.

    Have not tried Retumbo...

    All the usual reloading disclaimers apply.

    I haven't worked with the 280ak, but my 6.5-284 maxes out at 2880fps with 53 gr of 4831sc. I can get 2964 with Retumbo with 59 gr., no pressure signs.

    So far in my testing, NO. It is my favorite hunting powder so far.

    I hunt elk mostly in the snow. I shoot targets in much nicer weather.
