It sounds to me as if Brian wishes to use his 7 x 57 double rifle for deer, and not the more accurate 9.3 x 74R. And I think his question is our opinion of how he should sight in with a double rifle that is capable of about 4" 100 yd. groups. Considering that the left and right barrels group left and right of point of aim respectively, I think I would continue to use the same center hold and rely on a little Kentucky windage for those occasional long shots from a stand which are likely to be taken at stationary deer anyway. To me, sighting for more precision with the right barrel doesn't make a lot of sense if it means that the left barrel will be up to 4" off with a 100 yd. shot. 4" of built-in lead might be a good thing if a wounded deer runs in the right direction, but it would be a liability if it runs in the wrong direction. It might also be prudent to consider that this is not the ideal 200 yd. rifle, and to go with something more accurate when those across the field shots are more likely. This particular gun is still quite useful as is for still hunting in the thick stuff and stand hunting where under 100 yd. shots are more typical. Of course, when time permits, more extensive shooting to re-regulate with different loads might make this 7 x 57 more suitable for long shots.
