22 LR bullet drop calculator?

[Jetmugg]

Is there a handy on-line 22LR bullet drop calculator available that folks here use and trust?

I normally shoot a 1712 and SK Std Plus, and have my sight settings pretty well dead-on for all the distances.

Next week, I want to try shooting a semi-modified 10/22 with some Federal 719. Before I head to the range with the 10/22 and Federal ammo, I'd like to calculate the rough settings so that I finalize my sight setting pretty quickly.

Any help is appreciated.

Google "Simple Trajectory Program" STP is a shareware app and I have found if I enter the bullet velocity along with an accurate scope height measurement and best to my knowledge bullet BC, it gives me very close to the exact scope settings needs for all the other yardages within a couple of clicks. You can set it for zero distance and yard intervals and even print out charts in a couple formats. All that and the price is right

Federal also publishes pretty good tables on their website. 719's should shoot consistently to the same zero, just remember to get the lead out of the bore afterward.

you can try doing it yourself by shooting 25 yards then shooting 100 without making an elevation adjustment. measure the drop. then compare the real world data to just about any bd calculator to give you all sorts of info including b.c.'s of the particular ammo. you will need your real world fps, so shoot a few through a chrony if you can.

i have my data book out to 300 yards, but rarely do i shoot past 200. the above method got me pretty close
