So far...

Returned to the range today to lob some 10mm/200 biscuits at the 200. This time put up a target instead of balloons and had a spotting scope for feedback. Man that 10 inch black dot is small at that distance but it really is satisfying just to see you've hit paper at that range. Don't know that this would be called a "group" at 13.5" but gotta start somewhere. One shot was off the paper to the right of center. Really fun!

10mm/200
90 RS
Cabela's 50 cal. sidelock, GM barrel
open sights
200 yards

Our range doesn't have a 150 yd backstop......but it does have a 300...

For shooting open sights, at that distance, I would say you did real well. Personally I would probably not be able to even see the black dot. 200 yards is a long way out there when you do not have good optics...

wow thats a poke with open sights nice shooting

Gives you an idea of how good our riflemen were during the American Revolution when they were able to kill officers at 300 yards with their long rifles...

7 out of 11 would have done the job with that "group" @ 200

Good shooting yeoman!

Thanks for the encouragement. I have no idea what would make for "good shooting" as I haven't heard or seen posts from others at this distance. I would like to think that under ideal conditions I could shoot about half as well as at the 100 so maybe a 6 inch 3 shot group or 10 inch 5 shot group would be a good goal. I may put a spot of white-out on the front sight post to better repeat the front/rear alignment. There's no real practical use for this yardage I guess. Although it does make me wonder what might be achieved with a scope on this rig in antelope country. Any guess as to ballistic requirements for antelope death at 200 and what this 200gr Hornady with 90 RS produces out there? +/- 500 lbs maybe?

yeoman.. what is the rifle normally sighted in at? Also how much hold over were you using to make those kind of shots?

yeoman · 07-16-2007, 07:24 PM

Cayugad - I don't 'hold over". If you did that you wouldn't be able to see the target as it would be blocked out by the barrel. My gun is sighted dead on at 100 when I split the front bead with the plane of the rear sight. To shoot the 200, I elevate (by lowering the butt and raising the muzzle) the front bead and post above the rear sight plane. In my mind's eye, I'd call it 3/16" of front bead/post exposed for the 200. I wish the front post had horizontal white or fiber optic lines up its face so I could use one of them to settle on the rear sight plane. That's my thinking by putting a spot of white-out on the front post around 3/16" below the bead. It doesn't have to be in the exact right spot, just needs to be there so my eye can choose the same relative position. I believe a good pair of eyes can detect a difference of not much more than a human hair in relating front and rear sight position. Remaining error is in the hold, squeeze and follow through.

Cayugad - I should have mentioned that my sight picture at both the 100 and 200 is to barely reveal the target "dot" above the front bead, ,meaning just see its edge. I know some here prefer to reveal the entire dot or other variations. Since my front bead is orange fiber I guess I'd be wise to choose a dot color other than orange for the 100. Duh.. Glad I used the last one Sunday. Green would be nice........
