That's probably why they adjustable cheek peices and monte carlo style stocks. Cheek weld is imperative for precision shooting. Most people suggest a low profile scope mount system.

go to remington.com and find the remingotn shoot ballistics program. i use it and it seems to be pretty accurate. you can pic and weight bullet and style that they make in that weight. you can type in a sight in yardage and a zero yardage, for example my 7mm mag would nee to be sighted in a little under a half inch low at fifty yrd to be zeroed at 100 yrd. and dead on at fifty will hit dead on again at 150. its a useful program.

I think James B. hit the nail on the head. Although on paper a rifle in the 30/06 velocity class, with a scope mounted 1.7" above the bore, should be about 3.5" high at 100 yards when sighted in dead on at 25 yards; you might in reality be anywhere from a little low to 8" high at 100 yards. Don't shoot at a deerfurther than100 yards away until you get back to the range to check your 100 yard zero.

I always thought you were better off with a low scope mount rather than a high see through. What am I missing here?

elgallo114

Maybe a stupid question, but why don't you just start over and sight it in where you want it? I'm assuming you don't want the zero of a 300 win mag to be at 25 yards?

It would be way easier to bore sight at 50 or 75 yards, or even just start at 100 for that matter, then zero from there.

BrutalAttack

You're not missing anything. You're thinking correctly.

Roskoe

The only time I have used a 25 yard target for big game application was when I wasn't on the paper at 100 yards. Otherwise, you are right - not muchreason to shoot a pistol ranges. I would much rather be confidently zeroed at 100 yards and figure the 25 yard impact point from a chart, than be zeroed at 25 yards and figure the 100 yard impact point from a chart.

You will be shooting high from my experience. Here is a 25 yard calculation with no wind for Hornady 165 grain .300 mag. You can probably get away with dead-on aiming out to 300 yards.

(25 yard zero)
Range - yds. Path - in.
250
100 3.1
2003.4
300 -1.1

If you hit EXACTLY @ 25 yards then your bullet will impact 3 in. high @ 100,4 high @ 200,dead on @ 300

In theory this could be true if you knew the exact muzzle velocity of the load,the exact ballistic coefficient of the bullet and the exact height of your crosshairs above the center of the bore.
