Got my tripower sighted perfectly the way I want it:

at 100 feet POI is tip of chevron,
at 33 feet POI is exactly between lower edges,

e.g. @100 feet is top of reticle, @33 feet is bottom.

Works PERFECTLY for me, and is part of the reason I love the chevron.

Now, how off am I if I shoot at 100 yards?

Geeze! Who knows? That's way too much thought requirement for a sight system.

I've got a ballistic calculator in Excel from Forest that I have RIDICULOUSLY over-modified to include different BDC reticles like the ACOG, Burris Ballistic Plex, IOR, AccuPoint, and with a little tweakage, I can do one for the TriPower.

You can't do Ballistic calculations without velocity, bullet weight, ballistic coefficient, and height over bore, I'll assume your HOB is 2.6, but I still need to know barrel length (for velocity) and Bullet weight and type (for ballistic coefficient).

Are you challenging the forum to figure out an answer you already know, or do you really have no idea? I would just go out and blast something 100 yards away and see what happens. Thats part of the reason for owning these things, to go out and make noise!

I ahve no idea. sorry! ammo is 55gr 223 (though soon I'm changing all my rifles optics to M193 as I bought alot of that recently and sold all my commercial 223), barrel is a 14.7 (?) with permanent phantom.
