Isnt progress wonderful.
I don't how we went on years ago, we just went out and shot!

Zero at 50 yds with Eley subs. In my case 2 mil dots low at 100yds so 7"

You will need to find a bullet your rifle likes. Then after 50 yd zero shoot 5 round gps at 10 yd intervals and compile your own dope chart.
Only need to do it once.

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

If you measure your ‘real world’ drops at 10 yard intervals you can then go back to your calculator & adjust the MV value until it produces the same drops. This will then allow you to use it for intermediate ranges or to extend the distances.

As others have said though, getting the scope height correct (distance from centre of bore to centre of scope tube) is critical

I use the Element Ballistic app which is free. Easy to set up and has been good for me on steel targets at Bisley with my 22lr out to over 250yards.

yes box spec for eley subs 1025 fps

Agree with the chrono, you will not get near if you don’t know the speeds, i shoot eley subs too the average at 1072 in my rifle. As mentioned if you don’t have a chrono, zero at 50 and learn your drops for hold over past that.

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

What is the 22 LR scope you are selling?

What is the 22 LR scope you are selling?

its the Hawke scope with the hold overs pre printed on it for range, just zero at 50 yards and should be accurate out to 250 yards.

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!

The reality of making a good " drop chart" for your .22lr is .... its best done by actually shooting ! Find a place where you have a reasonably level bit of ground . Mark off every ten yards with 1" x 1" wood stakes and use these as your distant markers and simply shoot each point with a 5 shot group ( end to end ) and bingo ! Print or note down what you now know. This data can then be played with regards high or low groups and you can play with your top turret if any are too high or low . Remember though that change in ammo can make a fair old difference ( say Hi velocity ammo v your Eley subs )
shooting in different wind direction and force should be noted down ( include wind speed and direction of travel - NOTE IT DOWN ) Change in in pressure and wind again note it down . You will eventually be able to make good shots without constantly looking on you Data card .

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

The only way
