What do you mean by “max range”?how can you use Strelok to calculate the max range of a .22 lr ?

'Was thinking in terms of a safety zone around a range .. or if i shoot at targets over water what safety zone do i need behind the target ?

I tried using the Max point blank range calculation and giving it a very large height above LOS... the calculation appears to fall apart.

I remember reading that the best angle for shooting max range is around 35 degrees, instead of 45. This is because at 45 it loses too much velocity/energy rising up.

So lets use ballistic calculator and see where 35 degrees (multiplied by 60 to get 2100moa) and converted to 610Radians.

That gets us 1475m / 1610yds.

If we use 40 degrees which is 2700moa / 785R we get a max range of 1535m / 1680yds.

After that it just starts adding up degrees.

At 1720m - 1750m it grows from 10953Radians to 15375 which is over 600 degrees! That is almost two turns...

That lets me determine that Kestrel just starts adding degrees even after bullet is no more even flying to the wanted direction.

So that tells us the truth is somewhere between 1600 and 1700 yds.

Initially i thought that the answer would be somewhere close to where Absolute Drop = sin 45 x distance. but this is beyond the calculation window of Strelok.

If we use your suggestion of 35 deg then Absolute Drop = sin 35 x distance, this is also beyond the calculation window of Strelok .

27deg gives an answer of c. 1400m for Eley Match.

by 25.5 deg we still have an answer around 1375m.

22.5deg gives an answer of about 1350m

This appears to be pretty consistent but .... Given the sort of drops that i see when shooting anything beyond 200m i instinctively feel that 1400m is well beyond the real world reach of a .22lr round ... ?

I was hoping that there was a defined/correct/easy way of using Strelok to calculate this - one that i just didnt know

1680 yds for 0.125 BC.

I suggest you keep safe direction of fire and aim low when unsure where you might hit.

Remember that the bullet can skip off the water.

I know with rimfires the errors are easier to make because it takes so many clicks or even turns that you might forget something.

But I maybe would not overplay it, apply same logic as when hunting.

If you were to shoot an animal, you would not use any maximum range calculations. You aim at the target, not upwards the sky.

with a max range of 1600m unfortunately it is theoretically possible for a kid fooling around to give someone on the other side a headache by dropping a bullet on their head - not a good enough safety margin.

Yep, you are right.

You could try airguns.

Or shorts etc.

Not sure how far the 700fps rounds can travel, they might be good but rarely have accuracy potential.
