    As I can no longer get H870 for my 264win , does anyone have a suggestion for a replacement? With 77 gr. H870 and 140 gr. BTSP I was able to get chronographed mv in excess of 3150 with no pressure and great accuracy.

    Try Hodgdon's Retumbo or US869. Both are slow enough to get great velocity with such an overbore cartridge. You'll have to find some one with Quickload to run the numbers and see if they will actually work. I tried retumbo in a 6.5-06AI, but it was too slow and I couldn't get enough into the case to use it's slow burning speed. The .264 Win Mag should be able to benifit with these powders.

    US869, WC872, VV-N170, RE25, id try the US869 first.

    AA8700 is very close to H870, and gives very dense loads. Might also look at N165 and RL22 & RL25

    if I remember correctly, h870 was replaced by t-870 which is the same powder availible through Thunderbird cartridge co. I think if you google it, it should show up and click on their web site. You can find it there and fairly cheap too. I think it is somewhere in the ballpark of $80 for #8 of it.

    Get you some Retumbo. It really shoots fast and accurate in my 264 Win mag. I have a 27 3/4" barrel and I get 3350 fps with 130 Accubonds with Retumbo and 1/2 MOA accuracy.

    I agree, go with retumbo, and i do believe H870 is available as T870 from thunderbird....

    Strongly recommend you leave US869 alone, very high energy density, but very spike-y once you get to top end loads. Got great velocities in 6.5-300 win mag (Voodoo) but it just wasn't worth the sensitivity of the load.

    Use retumbo.

    My most accurate loads are with RL 22 and N165

    I use IMR 4350, with a 120 grain Barnes Tipped TSX and CCI 250 mag primer, through a 26" barrel. 3480 fps and 2 1/4 " three shot groups at 300 yards.

    The slower powders (H870, IMR 4831) I tried hit excessive pressure, way before reasonable velocities were approached.

    you might have been loading those really slow powders too light. They don't like that, and will build up excessive pressures for some odd reason (I don't remember why). Magnum cases like real dense loads

    The loads I used were 5% below maximum. Just did not work in my rifle.
