    I have over heard people say they sight in at 300 to shoot out to a thousand. What they are saying is sight in at 300 so you will have enough up clicks in your scope? looks to me like if you were to sight at 200 it would take just as many clicks to get out to a thousand because ,you have already used up clicks to get to 300? Any of this make sense? I'm confused

    I believe they might be referring to a MOA base and they can't get a 100 yard zero. Maybe just a 300 yard zero because it won click enough. Matt

    You are correct, for a given scope/rifle/ammunition/meteo combination, you will always need the same number of total clicks to get to 1000 yd, independent of starting your zero at 200 yd, 300 yd or at 71ft 7in on the Zero Butt at Bisley.
    The number of clicks is directly related to the elevation of your weapon.

    The best bet seems to be zeroing the scope at 100 yds, especially if you have a zero stop scope. Any time you change target distance, you simply screw the elevation turret down on the stop.
    That puts you at 100 every time, and that is where you work from.
    What I have done with my LR rifles is that, then putting a 20 moa rail on it. When you rezero after mounting the rail, you will be somewhere around 20 moa high. That gives you about 90% of the elevation left to work with.
    For example, I have an Eliseo Tube Gun in 300WM. With a zero stop scope I can dial out close to 1400yds.

    It has nothing to do with the amount of turret elevation. That's not gonna change.

    I sight in at 300 for long range shooting because if I am shooting in the center at 300 yards, my windage adjustment is usually good or at least very close the rest of the way out to 1K or more. I have sighted in at 100 and 200 before only to find my impacts on target are a little off for windage at ranges as close as 400-600 yards and even worse beyond that.

    I really like 300 yard zero for hunting rifles because anything from point blank to around 325 yards is a dead hold. 350-400 is a quick hold on the top of the shoulder to drop it in the kill zone and 500 is 1ft over the back. Easy holds to make if I don't have time to dial the elevation turret. I will always try to dial my turret, but sometimes things happen too quickly. Anything too far over 500 yards and I will dial no matter what because if I don't have the time to dial, I probably don't have the time to get steady enough to accurately shoot that far.

    with a 12-42 and a 15 moa base, i cannot crank to 100 yards, nor 200.
    at 200 i am 6" high and pretty much on at 300.
    i wanted to be in the middle of elevation to be able to do both 600 and 1000
    with out being near the stops in either case.
    so load work is doable at 300, and knowing i am 6" high, 200 will work also.
    with a 15-55 i can go from 100 to past 1000.

    After spending an inch thick stack of 20 dollar bills on the perfect scope, rings and bases, after mounting all that stuff you learn the scope axis with adjustments zeroed is 10.5 MOA off in some direction from the bore axis. The barrel axis is crooked to the receiver scope base screw hole's axis.
