    Here's the deal.
    You make your claim
    I call you on it
    We have a bet - you prove it in front of witnesses and I pay you.
    So.. make your play or just carry on playing with yourself. Put up or shut up.

    Sorry bud. I didn't realise you are a harmless fantasist - off to live in USA, conviction for assault, owner of several firearms. Dream on mate. Dream on

    I have done some filming similar to that but not using air rifles, I will bet that isnt 200yds, it will look like it through a camera being zoomed in and out but a 410E pellet wouldnt get to 200yds in that short a time no way

    I would say thats 100yds and once he had looked at his video he realised it could look 200yds, the time from ping to plop is way too quick to be 200yds and the amount of dust kicked up also shows its

    I would hazard a guess that the projectile would have to leave muzzle in excess of 1500fps if that was 200yds and theres no supersonic crack

    Now 34ftlb from a S410E and a JSB Exact would be about 970fps which would be just about right for 100yds and wouldn have a SS crack

    Its BS

    speed of sound is 1153feet per second bud thats why rimfire fires at 1050fps to be below speed of sound

    the thing that worries me with these feats is that they don't usually give data, no drop figures in MOA Mils or anything, the scopes on the rifles are not adequate for that sort of work and no one speaks of WIND DRIFT

    even if they turn down the magnification to get a wider view to hold off, then you can maybe hit a door but not bottles. the groups are already big enough at that distance so you need a fine aiming point.


    a 2 mile/hour wind full value at 170meters is already enough to put me off the 12" plate and a 2mile/hour wind is nothing, its that wind that you barely feel on the hair of your ears. At 4mph the wind starts creating that bubbling sounds in your ear which disturbs you a little.

    the nice thing about long range shooting is to put the pellet there with 1-3 shots. more than that and you should be doing something else. I expect anyone serious on his long range to have the elevation correct from the 1st shot and be slightly off for wind assuming the wind is blowing up to 6mph. the ones that empty a mag just to get there are a long way off.

    According to my Ballistics program the flight time should be around 1.5 seconds, using BC 0.020 and muzzle velocity 280 mps (919fps). He would have to have a holdover of 20ft and the pellet would have 2.2ft-lbs when hitting the bottle.

    And by the way speed of sound is 343mps(1129fps)

    Im getting realy curious if it can be done though. 200m…
    Doing the same calculation on a barracuda cal .25 at 1050 fps one would need a 10ft hold over and the pellet would hit with 12ft-lbs. Flight time would be 1 second and the pellet would travel 4.5ft over the sight line at its highest point.

    I will have to test this

    hi johan glad you are going for it, we are using the same gun after all.

    it will probably take more than a second to get there, even 150meters seems a long way when i squeeze the trigger. i'll bet it will be close to 2 sec for 200m. at 924ft/s 145m is running my elevation turret at 8.5mils(from 35m zero) if i remember well off hand. dat is 1.23m hold over. however im sure that you will break the glass bottle at 200m. im still going through .75" chipboard at that distance i wont run out of elevation this time, i've got 21Mils on my elevation in theory enough to 220meters but havent enough space available for that.

    Er I know that "bud" But a S410E will only run to around `1000fps max in .22

    My subsonic Eley plus .22 rimfire bullets shoot at 1080fps as do all the Match bullets from the best makers

    The speed of sound changes with altitude I am told

    Usint a .25 with heavy pellets at 1130fps you have a LOT more chance of achieving reasonable accuracy at 200yds and enough energy to smash a bottle than the one in the film

    I think hes a max of 120yds from the target, still pretty good but a LOT different to 200yds as the pellet will be dropping like a mortar after 100yds, as it does on a .22 rimfire

    I have shot tin cans at 300yds using .22 rimfire and subsonics, but it was on a dry field so bullet splash was easy to see (and richocets!) the holdover was quite a few feet but I cant remember how many as it was years ago

    All good fun though

    Who ever told you that need to do some reading, cuz its bull. Sound is not dependent on pressure, just temperature!

    But it’s a common miss conception since its normally colder at higher altitude! Doing the math on this, the post Robert .22 posted earlier is not wrong if he shoots at 35 degrees Celsius. The speed of sound increases with temperature.
