New Most Accurate load - 7mm Rem Mag
I was at the range today, and I came up with a new "most accurate load" for my Ruger M77 MkII 7mm Rem Mag.

It is a maximum load, so work up to it.

R-P Brass
63.0 Gr. Reloader 22
Fed. 215 Primer
175 gr. Hornady Interlock

4 sub 1/2-MOA groups...

Snoresville...... jrs you are only about 5 years behind the power curve. I've been using that load for that long with the same accuracy. The problem you will find is that the velocity swings wildly with ambient temperature... thats the main reason I dropped it: at 75 F. it gets 2920 fps, at 35 F. it gets closer to 2800 fps.

The load will shoot just as well, btw, with a WLRM primer, and/or a Sierra 175 SBT, and/or a Norma case.

But enjoy the accuracy until you find out for yourself !

Kuduking,
I finally got my chronograph, and when I shot this load, which is still very accurate for me, I got velocities around 2800 fps, with an outside temperature of 45 degrees. My other favorite load of 62.5 gr. Reloader 22 under a Nosler 175 gr, which is supposed to clock 2970 fps, actually averaged 2744 fps.

This is all much more interesting now that I have a chronograph....
