    sighting in a 260 at 25m where should i put it for minute of deer sholder out to 200

    i know this isnt ideal however i have my new 260 here and there is a range day tomorrow and im iching to shoot it however its been so wet getting the wheel chair to the 100m range maynot be possable if i am stuck at 25m where should i zero the gun so i can be pretty confident (on a sholder size target) out to 200m if i get a chance to hunt before i can get to zero it proper
    im sure i saw somewere with a 308 bang on @25 is 1inch high @100 and pretty close @200 im geussing with 260 being flatter shooting id have to sight slightly low

    is anyone able to give me an idea
    cheers

    Just pulling some numbers from my arse, if using a typical hunting bullet at 140gr and 2600fps with a 25y zero you'll get roughly the following trajectory


    The only issue is its real easy to be out by a little at this range and not notice it on the target, and that could add up to a big deal at 200y, so it's pretty crude.

    What session are you going to? If it's afternoon you're going to, I'll run your targets on the 100m for you

    This is approximate of course, I used a scope height above bore of 1.5inch but will be close enough for a shoulder to 200.

    Zero it ibn the bulls eye. At 25 metres you could be a bit off horizontally which might only show at 100

    Yes, dead on at 25m at the moment until you can test it at a more useful range.
