    Vette;
    If you really want the Hornady Superformance loads, see if you can get interbond bullets rather than SST's. I'm no expert but my PH really liked the GMX's and Interbond was his next choice. I used 129 grain Interbonds with great success. Our PH hunts with the Hornady guys so gets lots of expieriance with their products on plains game.

    My old Hornady catalog lists the SST as ideal for Whitetail to Caribou and similar sized African game. Good for classic behind the shoulder and soft tissue shots. The Interbond says it is designed to expand immediately but retain more than 90% even through tough hide and bone.

    But with good shot placement, I'm sure either will do the job.

    After a long hot summer ended with a move to a different home, my garage is taking shape and with it my new reloading bench. Finally, this week I started up loading again. Somewhere along the line I picked up some H4350 and wanted to give it a try in the 7x57 with the same 140gr North Forks and all other aspects the same as above.

    Loads started centering in nicely at 48gr and tightened up slightly at 48.5gr giving a group similar as above. Chrono average of 2730fps. No sign of pressure whatsoever. So, I'm going to keep bumping up the load until the group opens or start seeing pressure signs.

    There's a simple cure for that. Stick a bolt so hard it requires use of a 2x4 and hammer to unstick it. And when the brass comes out, the primer pocket is more of a primer trench.

    Good call, I left brass on the bolt face the one time I did it. Once was good enough for me.

    I have a 7x57 and its my all time favorite caliber. You just purchased one of the best 7mm mausers in production that i have seen recently. Good bullets can do anything and I tend to stay with 140gr with all plainsgame species including the Eland. Your 160gr would work even better since there will be more penetration and I will say the the 175gr bullets put kudu dead in its tracks and will work wonders on eland. You dont have to take your 416. I only see people wounding/missing plainsgame with calibers like that.

    Winchester no longer manufactures the M70 in 7x57. I used to have one but it had barrel issues and when I sent it back for a replacement I was told I had to pick a different chambering because they no longer made the 7x57.

    Quite certain it was a limited run, they're not advertised on their website anymore. Don't know how many they made though. Fun gun to load for and shoot! I'm a bit envious you have one I must admit.
