Being a jarhead that was used to hitting 10 for 10 @ 500 yds with the A2's iron sights back in the day, I may have unrealistic expectations.?. I am much older, not as lean, and certainly have poorer eyesight.
I haven't coined up just yet. I am vacillating over one of three models (3 are in my cart at the moment), struggling to make a good decision about the zoom/objective size vs keeping optical boresight as close to the bore as possible. I'm currently leaning towards the 6.5-20x52 on a set of Burris Rings. Others being considered include the 4.5-14x50 and the 3.5-10x42.
EDIT: Here is where I got the 40h x 40v MOA figure.
From a post @NugginFutz made. I too tried to find sumtin on Hornady's site - no joy.
Mh:
10 X and 14 X are not a good choice for precision work at 600, let along 1000.
20X would be the low end I would consider at 600 and having used 20X extensively, I went to 26X and will go to 30 X in an instant.
Hold overs are not the ideal solution for precision shooting and particularly with the low velocities found with a 30 grain 6.5mm cartridge as the Grendel.
The guys have commented on field of view and clarity when someone is using a stadia line far from the center of the optic. I will add four other problems when using hold overs.
First, if the distance is such that you are between lines, you are basically guessing at the hold. May not mean much but with a low velocity cartridge where the danger space is short and at longer distances, guessing where to hold between stadia is problematic.
Second, if your rifle is canted when using a hold over, you just put windage on it. Guys alleviate this by using levels attached to the optic. That assumes they mounted the optic perfectly in relation to the axis of the bore. Guys assume the axis of the bore is in line with a flat on the receiver and that the rail is also made perfectly. Not always true, particularly with cheap barrels.
Third is holding a stadia for wind when you are using a horizontal stadia that is well above the middle of the optic. Like using a three mil hold over for example, then a windage hold from that. Unless a guy is using a grid type of reticle that for many is too cluttered to be of value, he is guessing on where to hold for wind. And he will have a greater tendency to cant the rifle when using a big elevation hold.
Forth, we as humans are hard wired to look at the center of objects. It is our natural tendency so shifting our focus to something away from the middle tends to detract from precision. Even if there is a stadia line to look at. It requires a lot of focus to use extreme holds repeatedly and precisely.
If you want to use a Grendel at 10000 with any degree of success you are better off using the main cross hair located in the center of the optic and indexing the right elevation and windage. Or using the center cross hair and holding for wind. You are better with a Vari X that gives you up to 30X or so. At about 25X in most conditions you can dope winds through your optic providing the glass is of decent quality. Seeing mirage through the optic is a good thing because the Grendel will not give you anything at that distance so your holds for wind will be constantly shifting and most likely you will have to depend on mirage to see shifts and to estimate speed.
