Ballistics Calculator 22lr

[Jason The Turner]

I've used shooterscalculator.com but am finding reality bears no relation to the calculator (more than 1 inch different at just 30m when zeroed at 20) I'm guessing barrel length may be a reason for the difference between theory and practice as I'm putting all the other data in, including atmospherics.
What are the 22LR pest shooters doing for 50-100yd shots? are there reliable ballistics calcs for this ?
many thanks

FYI - I have a background in target shooting so I'm getting very good grouping at known distances but that's not helping me with the bunnies!

What are you zeroed at 20 yards it's not an air rifle. 50yrds is standard and point and shoot to 70mtrs after that you'll need some hold over.
I use the hawke 22lr scope. It's excellent with hash marks every 10mtrs I think. Zeroed at 50 yards I've shot out to 120yrds with good success.

Does that mean you're using the "box spec" for velocity? You'll either need to chronograph it, or else make some educated guesses to adjust for barrel length until the chart resembles real-life more closely

yes box spec for eley subs 1025 fps

CICO, unless you chrono your ammo, everything else you input is pointless, or do it old school, zero at 50, then shoot groups out to 100 at 5 yard intervals and make note of the drop

I use Strelok Pro and find it very good, but you need to test extensively to validate the App. Scope height is critical too. I test indoors first before I shoot outdoors.

I just zero at 50 yards and test hold overs beyond that. Different ammunition brands or types will have a different drop and POI.

I didn’t think that was still available now

Try Chairgun elite.

It's not the particularly easy to get updates, but I have a copy purchased from the Huawei App Store and have managed to keep it updated on my Android phone and tablet. I had originally purchased the App on the Google Play Store. I've just been collating my dopes for the NRL Hunter Match tomorrow and am about to print them off.

Strelock pro is the best but due to it being Russian, it's not been updated on Iphone for 3/4 years now

i use an Alpex on My 22LR and with the inbuilt calculator it is spot on.

zero'd at 50 yards, shot a hare last week at 135 yards. clean shot.

if you are looking for a designated ""LR scope i have a Brand New in the box Hawke one for sale

When you do have all your accurate data, use JBM ballistics to get a decent usable drop chart, you can also use it to find out your optimum zero range

This. I’m finding the Alpex Lite very accurate for .22lr Norma subs out to 90 yards - silent one shot kills on rabbits

i use ballistic AE and find it superb , if i may i would recommend a slightly further zero point , i use 50m

it's important to be accurate with your data input - crap in crap out !

for example don't assume or guess your scope height it has a bigger effect than people realise

I use the same calculator as you and I find it to be very close.

I would firstly obtain an accurate muzzle velocity and feed this into the calculator and secondly find somewhere that you can obtain a 55 yard zero. I have run your numbers through shooterscalc using an average of Eleys MV and a 55 yard zero this gives a near zero of 25 yards and a far zero of 55 yards. Between these two zeros the maximum elevation is .45" and this occurs at 40 yards.

Calculates the ballistic trajectory of a bullet fired from a rifle, handgun or other firearm. Produces a ballistic trajectory chart and table that shows the drop, velocity, kinetic energy, windage, and trajectory of a bullet.

thanks to everyone for the input, I don't have a chrono (yet). So, being an old-fashioned kind of guy, I'll do it the old fashioned way - and measure drop over distances to produce my own chart.
Seems like a chronograph could be on my birthday list though

Thanks for the reply, didn't really twig that variations in MV from the box stated would have such a major effect. thanks for the link too.

I think @suburban bushwacker had a chrony for sale recently
