Not really young eyes, just really good contact lenses that take me a bit better than 20/20... I'm not sure I could shoot much better than "minute of deer" at 20ft without corrective lenses though...

I used to shoot some 600yrd CMP matches through iron peeps, did a lot of smallbore indoor with peeps where the targets were equally difficult to see, used to do some bp silhouette and cowboy action long range shooting 300-600yrds with tang mounted ladders with both peeps and V's in leverguns. Nothing nearly as accurate nor as "easy" as scoped shooting, but given the right target to pick up well, it's not that bad. I thought pretty heavily about peep sights, but I haven't found a way to mount a peep to a Ruger M77 that I really like yet.

So I suppose that's the real motivation for this little project. I used to have a lot of 'excuses' to practice shooting open sights, but these days, I'm not competing at all, so the only open sighted shooting that I do is on handguns, and I find myself putting scopes or dots on most of those anymore too.

Considering the speed on one of these rifles to which I'd like to add sights, a 100, 200, & 250 set probably makes sense (maybe even a 150 in there). The other rifle I suppose could even get away with a 100 and 250 with hold-over for 300, or 100, 250, and 300.

Too spoiled by dialing come-ups, hard to go back to irons without some kind of corrections!
