need scope help

I am shooting a rem 700 sendero 300wm with a nightforce nxs 5.5-22 x 56 with a NP-R2 reticle. I have always shot regular hunting set ups but am now trying to learn a more long range set up. I am having trouble understanding at what rate the moa marks change with different magnifications. I am basically banging my head against a wall trying to get a full understanding of the scope. If anyone knows any good sites to visit where i can get a more in depth description of how to use this scope the way it was designed to be used, please post

I have the same scope. Once you put your scope on 22x power, then you can start figuring out distance to target using your NP-R2 reticle. Bracket the target with the vertical line. It the target falls between hash marks use your judgement for tenths of a M.O.A. With the known size of the target the equation is as follows:

Size of target in inches / M.O.A. x 100 = range in yards

Once you know the distance to target and your bullets ballistics you can either input the correction on the turret, or if the target is within range, you can just use the vertical hash marks to compensate for bullet drop. Note* dramatic incline/decline angles will have significant impact on the true range. I recommend the Night Force ballistic software for either a field PDA or you can get the desktop version and print out a ballistic table for a specific load. You can laminate it and keep it on your person in case your hunting in wet conditions... Also, Night Force makes an angle degree indicator that you can mount on your rail under your scope which will let you know the exact incline/decline. This info. can be plugged into your software to give you precise adjustments. A hand held weather device is also a good piece of equipment own for temperature, humidity, altitude, barimetric pressure, muzzle velocities.I hope this helps. Once you get the hang of it, that reticle is BAD ASS! I know it sounds like a lot of things you have to do before you get a shot off, but once you practice it becomes second nature and you can do it all in a few seconds. Good Luck!

It's not as hard as it may look, I promise. Very simple for ranging and holdover.

On 22X, the vertical spacing between marks should be 2 MOA. Horizontal should be 5 MOA.

On 11X, those same brackets will now cover twice the area. 4 MOA vertical, and 10 MOA horizontal.

On 5.5X, the spacing will be 8 vertical, 20 horizontal.

S/M=D..............size of target / moa covered in scope = distance to target
MxD=S.............moa covered in scope x distance to target = size of target
C/D=M...........correction needed at distance/same distance = moa to hold high. This one works for wind too.

Example: Rangefinder batteries died. Deer measure about 20" back to belly, you see a deer that covers 4 moa in the scope. So, 20/4=5............deer is approx 500 yds away.

Example 2: You know the distance to same deer is 500 yds from your laser rangefinder, but you don't know how tall his rack is. His rack covers 4 moa in scope. So, 5X4=20.............deer's rack is approx 20 inches tall.

Example3: You know that the 15 mph wind is going to blow your bullet off 25" at 500 yds. So, 25/5=5............you need to hold 5moa into the wind to hit the deer with the 20" rack at 500 yds. You've done all this without dialing a single knob on the scope.

Hope this helped.

Re: need scope help

You're welcome

These equations are not precisely exactly accurate, because an MOA is actually 1.0472" for every 100 yds. But they will get you within an inch or two and do it pretty quickly.

Good Luck and enjoy the scope, I sure like mine.
