This is off the bench, sitting position (butt on the ground) at 50 yards.
Next week I'll be taking this sweet pea Deer hunting for the first time to try and fill a remaining Doe tag.
I'll be hunting in a thick area that 50 yards or so is a long shot.
What can I expect at say 15 to 30 yards? how high or how low?

Bad me, I should have done that.
Going to the range right now would be a nightmare. (wall to wall people)
The closest target frame's to the shooting line is 50 yards.
In looking at 10mm, 40 s&w, and 357 pistol data at 1200-1300 fps I'd guess about an inch low at 25 and 1.25 low at 15. In other words, no difference in the woods.
Sighted in dead on at 50, there probably won't be enough difference at any range less than 50 to matter. Not sure what velocity you're getting from your BP load, or the ballistic coefficient of your bullet. But looking at Winchester's site: http://www.winchester.com/Products/rifl ... X3840.aspx
I used their info for a guesstimate. 1160 FPS muzzle velocity, 0.172 BC. Plugged that into Hornady's ballistic calculator: http://www.hornady.com/ballistics-resou ... calculator. It shows you'll be about half an inch high at 25 yards, and about 2.5" low at 75 yards. Again, just an estimate, but should be close. Good luck!
cshold -- my little ballistics calculator with my guestimates (such as velocity -- 1230 fps, sight distance above bore = 2cm) says you might be .1" high at 15 yards and .5" high at 30 yards with a 50 yard zero. In other words, with the level of precision exhibited by your weapon you are not going to be able to detect any hold difference. As Hawkins and Blaine already indicated...

Since a flying boolit crosses the rifle's line-of-sight twice, first @ about 25yds on it's way "up" & 2nd @ about 100yds on it's way "down", a 100yd zero should result in the boolit's POI being about 1"-1-1/2" "high" @ 50 yds.
With a rifle zeroed at 50 yds, as posted above, there should be little-to-no difference in the POI @ the shorter ranges.
