I got to shoot my Wby in 7mm Rem Mag this weekend. Just loaded the magazine with three, hunkered down on the bench and fired as fast as I could get steady.

Here's the 1.125" group.



I haven't fired this gun since last fall (and God forgive, nor have I cleaned it). As I said in the SD article, once you find a low SD load/gun combo, you can expect the groups to stay within predicted if you can do your job at the bench.

As I said in the article, the Speer 160 had an SD of 0.92 +/- 0.41 and this 1.125 group landed right in there.

For those of you that may have missed the article

thanks TT,
It's not that SD is some magic bullet for accuracy, it just helps to understand what to expect from your rifle and when to quit chasing tight groups. As I said at the end of the article- it will save you a few cuss words, too. :)
