True 100yds or MPBR zero

Was wondering what most people do. Sight in for true zero or sight in for max point blank range?

I'm new to target turrets and have always hunted with sighting in for MPBR and adjusting from there and not sure what way to go from here.

Thanks for any input
Tony

    I prefer MPBR with a drop chart starting from there.

    I sight in @ 500 then back the turret down what my program or drop chart called for at 500 and zero the elevation turret. I don't worry about an inch or two at 100.

    It depends on the kind of hunting I am doing. If I am using a dedicated long range rifle I set my zero at 100 yards and dial everything.

    If I am hunting in the woods and small openings I will still start with a 100 yard zero but then I will spin the turret up to 300 yards and hunt with it set that way. When I am through hunting, I will spin it back down to 100 yards (if I remember).

    I find it comforting to have all my rifles set up the same way so I am not scratching my head trying to remember how the rifle is set up when it is time to shoot.

    MPBR has been around a long time and is still used by a lot of
    hunters that generally shoot/hunt 100Yrds to 400 yrds at
    big game (Kill area around 10 to 12 Inches).

    With the advent of range finders the need for MPBR has diminished
    and accuracy at all distance is better with a droup chart and a good
    rangefinder.

    I normaly zero at 200 and turrent up from there .but a 100yard zero
    makes a lot of sense if you use a range finder and a good drop chart.

    Also with a big slow bullet with lots of drop the MPBR doesent work
    very well but the drop chart and range finder method does.

    MPBR works best with very flat shooting calibered rounds(Like the
    7mm STW).

    On my hunting rifles I use 300 then check it at 600 and 100 just to make sure that the Oehler is correct. Mine are all customs that will shoot .4 MOA or better so I know that the results are pretty much dead on. Each range gets a 5 shot group to verify. Do this with my competition rifles as well but those ranges are 600 and 1K.

    Re: True 100yds or MPBR zero

    I use MPBR and drop chart and SHOOT. Then shoot more to insure that this is all true.
    I'm zeroed @ 336 yards I'm pretty much good out to about 0 - 370 yards MPBR.
    I test and check utilizing kentucky windage and elevation from that point further.
    currently out to 550 yards.

    Most of the time I don't have alot of time to perform CLICK setting in Hunting situations.

    I think if I were to do very long range that the
    Broz
    I sight in @ 500 then back the turret down what my program or drop chart called for at 500 and zero the elevation turret. may be a better way to go.
    Seems to make since

    Start to insure grouping at 100 yards then look over ballistic chart for the
    Bullet weight, Load, Velocity and Trajectory.
    Then get the bullet to land @ 100 yards to be zeroed at desired down range for dead on ZERO for the down range zero you desire.
    Example: 6.7 inches high @ 100 yards to be zeroed @ 400 yards
    Then shoot and shoot and shoot, trigger and scope time will only make you a better shooter.
    Remember the wind my friend... .. .

    BEST OF LUCK.
