    I'm shooting a 7 Remington Magnum with H4831sc, H1000, Retumbo and WC872 with great success. I mostly use the 162 and 180's you mentioned, and have also had great luck with the Nosler 140 BT and 160 Partition.

    I've changed computers and can't get any of my load information out of the old one right now.

    If I remember right, I was shooting right around 2900 or just a little over out of a 26" barrel.

    I wasn't thinking clearly on my previous post. The Nosler partitions are 175 grain. I've been reading a bunch of ads for the new 160 grain accu-bonds and the number stuck in my head.

    They were shooting 3 shot groups well under MOA at three hundred yards. Most groups had two shots about 3/4" apart and the last shot about 2" higher. It was about to drive me nuts why the third shot kept going high when I ran out of powder.

    I picked up two more pounds the other day but haven't worked on it since. I've kept busy playing with the WC-872 I picked up the same day.

    A full case in the 7 mag is right about 80 grains of wc872. With the 162 Amax's I got a stiff bolt, but about 3/4 MOA.

    I switched to the 140 Nosler BT's and things were looking promising. First few loads were easily 1/2 MOA or better. But this POS factory stock seems to have warped and is now once again touching the barrel. Fliers are getting more frequent with every shot fired. [​IMG]

    I have a 7mm stw. 34 in barrel and behind 74.5 grains of H1000 am getting 3100 fps with the Berger 180 gr.
    Very good accuracy and no pressure signs. Have also used H870 up to 89 grains but didnt get group size or velocity readings but should be close to same as H1000.

    Do you guys hunt with the big Bergers or any of the Bergers in general?

    They seem to shoot really well, I was wondering about the performance on game.

    Is it similar to the the Sierra Match Kings?

    Everything I've shot with the Berger's has died.

    How long is your barrel?

    Do you know the case capacity in grains of water?

    In my 7/300 Weatherby Mag. which compares almost identical to the STW case capacity, I use 87 Grs of WC-872 and the 162 Hornady match or the 168 Gr Sierra MK.
    Great hunting loads.

    Shoots extremely well from the 30" barrel
