Open sights at 100yds with older eyes

Globe/aperture front sights only work well if/when the target can be tightly
circumscribed by the ring.... And that depends on target size, shape and range.
(But when all that fits together, aperture/aperture can be laser accurate.)
FWIW, I use that on my two Sharps against both paper and Rams.

Still, I like the 6 o'clock post since all I do is mentally adjust for ~a post-width-high
impact point and all is well.

MEH, I totally agree on all your points. It's not hard to compensate for oddball stuff as long as we know how big it is. I do the same thing when not zeroing on on the proper size target at a given distance.

But I suspect we also agree that if the little dime size "X" in the middle is the spot we're after that the parameters used for the 6o'clock hold need to be consistent.

And to Squeakywheel if you should venture into buying a globe front sight this is also why the sight comes with a wide range of inserts. There's various round inner circles to suit various size black spots at different distances as well as "x's and o's" cross hatch lines, flat top and pointed posts and a broken out middle + sign insert. If you go for a globe front and can't find an insert to make you happy then you are one FUSSY and cantankerous sort of hombre.....

I absolutely positively cannot shoot with iron sights. I mean I can't shoot at 20 yards. My eyes just will not focus on both sights and target.
My peep sights help a lot as I can focus on just the front sight and the target but I still can't shoot at 100 yards. I hate it because I grew up with a 30-30 and 30-06 with open sights for deer hunting.

Oh we absolutely agree.

No one can focus on both the sights and the target. It is optically impossible for the human eye to focus on two different objects at different distances at the same time.
If you are trying to do so, that may explain your lack of success.

OK, now you're just showing off!


That is some darn nice shooting. And a main battle rifle to boot!

For shooting at the range with my bolt action milsurps, I went to Jaggi Novas and took one of my rifles to the optometrist so we could try different corrections to get a perfect front sight focus. Knobloch, Champion, and Varga all make similar orthoptic glasses. I shoot a 42 cm lens to get more protection from a blown primer. If I was shooting AR's or something where I had hot brass flying and wanted more protection, I would get ESS/ICE or some similar wraparound with a corrective lens insert. If you go to an optometrist and ask, they can set up a set of glasses with a correction for the front sight and move the optical center of the lens so it is correct when you are on the rifle. With the Novas I can move the lens to wherever I want it for positions and or different rifles. They look goofy but work beautifully, and after the initial investment all I have to do is get a round lens made with the proper correction.
