    Does anyone have information use on a thermometer target ? I understand that while keeping my scope doped at, say, 600 yds I can shoot at a thermometer target at, say 100 or 200 yds and still practice shooting as if at a 600 yd target. How is the target made?

    Thanx much for any help

    That's easy; make an aiming point and draw a vertical line up off the center and make reference marks where the point of impact above the aiming point should be at appropriate ranges.
    Example with my .308: precise aim point at the bottom of tall paper target (I like to use the corner of a square with riflescopes for aim point), vertical line straight up, reference mark for where I expect the trajectory of my bullet to be at 100 yards with 600 yard zero= 16.32" above point of aim and a mark at 28.70" for 200 yards.

    You need to use a ballistic calculator and punch in all your info to get the impacts above point of aim for your specific setup and environmental conditions.

    This is also a method of calibrating your scope, or rather finding out what your scope actually dials. It may dial more or less than actual moa, once you find out you can compensate for difference. Some ballistics app let you input a correction factor which will then automatically account for it at all ranges.

    Yep, I check mine before waisting any ammo. Then check the scope adjustment's accuracy/reliability under the stresses of recoil.
