22 cal bullet rise and drop
 
I have looked at several ballistics charts and can't find clear data.....Each chart was based on having the weapon sights zeroed at a specific distance....

I want to know what an average 22 cal bullet can be expected to do from the end of the barrel out to 100 yards...(at 25, 50, and 75 yrds).....

Also is there a method for computing zeroing scopes that are at various heights above the bore?

Thanks................Dan

Federal 22 long copper solids zeroed at 50 yards . This should get you relatively close
yards -------- velocity ------ energy -------- drop
0 ----------------- 1239-------- 136--------/ -0.50
25 ---------------1162-------- 120 ---------/ 0.6
50 --------------- 1099--------- 107 ------/ 0.0
75 ----------------1048 --------- 97 --------- / -2.4
100 ------------ 1006 ----------89 ------ / -6.7
125 ------------- 970 ----------- 83 -------- / -13.1
150 ----------- 938 --------- 78 --------- / -21.9

Thanks for the reply, but the chart you posted is from a zero of 50 yards........I am hoping to get a trajectory for a bullet from the end of the barrel out to 100 yards. (the natural unaimed flight path of the bullet)

If a gun is completely level and shot regardless of caliber, will immediately start dropping due to gravity. There would be no upward movement. Sights/scope are made to intersect the bullet at a particular spot(zero) thus giving the correct angle for the bullet to rise and fall through POA

Exactly what he said ^ . There is no such thing as bullet rise from a level gun barrel. :cool:

Ballistics Calculators
 
Why donít you play with these for awhile. You can select and sort for rimfire, change your zero, change your range, etc:

The Winchester is online;

The Federal is a download;

You can download Winchester ballistics calculator from the Internet and it will allow you to set any sight hight above the centerline of the bore and enter any Winchester and some Remington shells for 22 on up if you set the sight in distance at 0 it will show you the drop out to 500 yds.. It's a free download. A 22 drops 9 to 12 inchs. At 100 yards from a level barrel.

As the folks have said- bullets do not possess the secret of antigravity, and do not rise unless the muzzle is pointed up.

To visualize, go get the garden hose with a nozzle. Set nozzle for solid stream. Hold nozzle perfectly level. Water spray will drop as soon as it leaves nozzle. To hit something further away, tilt nozzle up. Water will go up, and drop back down in an arc.

I guess what Im getting at is that from zero its going to drop , no matter if its 0 yards or 50 yard zero .

Here is a calculator I use to get an estimate of trajectory.

http://www.handloads.com/calc/

Enter the appropriate data in the spaces above and click the calculate button in the upper window. Default values are provided in all of the spaces just change the ones you want. A range table will then be displayed in this window. The inputs that are less likely to be changed are located under the calculate button in the upper window.
