That seems about right, except I think that you mixed up the 50 yard and 50 feet one.

Absolutely not.

Well, then that is really messed up..

Not at all if you understand how the world works.

The bullet is starting about 1.5" below the line of sight. To intersect with the line of sight at 100, it has to cross it rising, and then drop back down at 100. (Some centerfires shoot so fast/flat that they cross the line of sight first at 100 yards or more, depending on sight height, but no .22 LR shoots that flat.)

It will hit its highest point about 60-65 yards out and then be falling from there on.

It first crosses the line of sight at about 30 feet or so. It's still headed up at 50 feet, still headed up at 25 yards, and still headed up at 50 yards, though it will very soon start back down.

Sighted at 100, after 100, it starts coming down fast. Notice that it drops more in the next 25 yards than it did in the 40 yards before that.

Snake45,

I'm curious as to why you would want to sight in your .22LR at 100yds? This trajectory results in the bullet going so high above the line of sight at 50-80 yards that you have to be a very accurate judge of your target distance to know how much to compensate at those distances. Unless you are only shooting at 100yd targets, I'm having a hard time understanding your reasoning for a 100yd sight in.

Because I will mainly be shooting this rifle at 100 yards, as it is accurate enough to make it interesting. That, and plinking at rocks/leaves/dirt clumps on the 125-yard backstop.

BTW, at my club range, it is not possible to shoot at 50-100 yards. The ground drops away into a mini-canyon just past the 50 yard line, and is not visible again from the firing line until 100 yards.

Has anyone here , learned how to use a duplex reticle???

With my 100-yard zero, at 125, I just put the rock or leaf or dirtclod on the backstop exactly halfway down the vertical wire to the point where it widens, pull the trigger, and the target moves, jumps, or simply disappears (as appropriate). Works every time!

My Winchester 69A is sighted dead-on at 50. To hit something on the backstop, I put it right where the lower duplex wire widens, bingo, same deal.

125 yards is the farthest range I have access to, so that's as far as my interest goes for the time being.

Truth to tell, these days I do most of my rifle shooting either standing or snap-shooting (offhand) at 50 feet or 25 yards with various peep or open sighted rifles. It's all a matter of angles anyway, why walk down 100 yards to see that I'm shooting 6-8 MOA offhand when I can learn the same thing at 25 yards or less--and see the target more clearly besides?

But when I'm in the mood to shoot at 100 off the bench, or at least prone or slung-up sitting, my 100-sighted CZ will get the nod.

I don't think I know this position. Got a description of it?

It's one small step for a man....

federals web site will do an instant analyisis of all their bullet trajetories:Blasting_

Do you get a commission from them, or something?

Computer programs and caluculations will get you on the paper, but every gun and ammo combination is a law unto itself, and the only way to KNOW what it will do is to SHOOT IT.

Fortunately, this happens to be fun.

 

[Snake45]

This is really an interesting thread. Snake, I have more fun plinking at 100 yards and over. Small pieces of clay birds are a riot-they just vaporize!

Me too! I just love bouncing a leaf or small rock around on the 125-yard backstop.
