1000yd Question

[T 700]

OK, i am wanting to shoot in the 1000yd IBS, I have a NF BR 12-42x56. Question is with a 20 MOA Rail and zero at 100 will i have enough clicks to get to 1000yds, Shooting a 6 Dasher with a 105 Berger, runing around 2950.


Thanks T 700

Yes!

You will need about 25 Minutes from a 100 yard 0.

Thanks for the info Terry

You are good to go.
Where are you shooting at?

Once you have a good zero at 100 set your elevation at zero on the scope and retighten it. Add 25 min. of elevation and you will get a hit at 1K. Windage will change with the condition,so will the elevation if you have a head or tail wind.........jim

As they said, start with a 100-yard zero. Your NF has how many MOA elevation total ? 40 MOA according to their web page. Subtract the MOA or "clicks/8" that you used to get from a bottomed out elevation zero to 100 yads. This is your remaining MOA. Note this number for future use. Punch in your 105 Berger from the bullet list at 2950 for 1000 yards and note the drop MOA in results column 3. Using Litz and the 105 VLD with no other scope correction I get 29 MOA. Unless you used more than 10 MOA to get to 100 yards, you'll have plenty. You don't even need the 20 MOA rail. That's simplified but it has always worked for me.

Or, you can set the zero for 100 yards and the target range at 1,000 yards. calculate and read the drop MOA at the bottom of column 3.

I use a similar set up, 6XC at 1000. I have had great luck by shooting over the chrno, looking up the data on a balistics chart, set a paster down low on your 100 yard target and measure up the recommended amount in your balistics program and crank up your NF to the new target spot. Always got me on paper at the 1,000 target. PS by the way it helps to use a level to insure that your come up is vertical.

I'm working on the same type project with my new 6mm BR, only using a NF BR 8-32. 1000 yards is workable even with a 0 MOA base on my rig.

My Dashers are spot on with Terry and Johara1 info, give or take a little temp and humidity changes I am on with 23.5-25 MOA. My 6*284 is 250 fps + faster and it is almost alway 21-5/8's MOA

With the 12-42 NSX and a 20 MOA rail I have no problem getting out to 1000. The problem that arises for me from time to time on different guns is that I can't get down to 100!!

Using a 12-42 NBR, a 20 moa rail and Signature Z rings (with 0.010 inserts) I can do 100 - 1200 with about a minute of adj left at each end of travel. Shooting a 6.5/06 Imp.

My stiller diamond back/MBR stock-Lawton 7500/st-1000, and Bat 3L/Edge,
All wearing 12-42 NF BR scopes and 20 moa Badger ordanence base and rings I have oodles of movement at 100 yards and at 1000 yards I have oodle of vertical up left so I just can't imagine you having a problem there all 6mm's from 3030-3300 fps.

I would be carefull with this piece of advice. True, the NF BR 12 x 42 has 40 MOA of adjustment..... but that only gives your 20 MOA of up and 20 MOA of down. NOT 40 MOA of total up. Typically, your scope will zero out at 100 yards with either +5 MOA or -5 MOA.... somewhere around the neutral point of adjustment of the scope. the 20 MOA of elevation built into a scope base will now allow you a total of 40 MOA of up and 0 MOA of down. give or take a few. So, to answer your question.... YES, you will more than likely need the 20 MOA base to give you the 28 or 29 MOA of elevation to print your 105g bullet on paper.

Thanks for all the info, Now all i have to do is apply it to my gun and scope.

Thanks T 700

Zeros and Settings

Yes, PM made a good observation. It would depend on where your scope zero for 100 yards is at. My scope has 45 total MOA elevation, and it uses 7.25 MOA of that total to get on at 100 yards. Leaving 151 1/4-inch clicks or 37.5 MOA left in elevation up adjustment. Easy enough to hit at 1,000 yards.

Here is what I was trying to say:

Unless you used more than 10 MOA to get to 100 yards, you'll have plenty - Edit: from a bottomed out negative scope elevation setting

Semantics aside, the scope does not have 20 MOA up and 20 MOA down. To my way of thinking it has 40 MOA adjustment, but it could be 40 MOA up, 40 MOA down, 15/25 20/20 but it all depends on where the starting zero is. And what is used in which direction to get there.

In his (PM's) post, an given is assumed that the 40 MOA is split 20/20 up down from a 100-yard zero. That was not the case in my setup. I have only used this one scope, other than scout type mounts using pistol scopes for under 200 yards..... I am a total fledgling here. Anyone ???

Interesting, then. Is my receiver angled or why else the huge disparity between my inexpensive 1990's 6x24 Taiwan scope and the Long range Precision Night Force ? My zero neutral at 100 yards uses only 7.25 MOA of the 45 MOA, not 22.5..

Ahhh I think you answered your own question. If you were to call NF and talk to NF Ken. He will tell you that "most all" NF scopes are Zero'd close to center for elevation and windage (total movement.) In this case the BR 12x42 which has the 40 MOA of total adjustment. (elevation) Now if you have poor quality rings or the Burris signature rings w/ inserts, or a Rem 700 action which are never on a true plane, then you may have some + or - adjustments off of center (neutral) setting on your turrets.
So, in a perfect world....... your 20 MOA base with your NF 12x42 BR scope will have 40 MOA of up and 0 MOA of down.

 

[bozo699]

I have a 12-42 as mentioned on my Bat and I checked it today, zeroed at 100 yards I can turn the turret one full turn down plus about 1/3 more, I didn't count the clicks but that is ball park figures, and I have absolutely NO PROBLEMS reaching 1000 yards and beyond and I have a 20 moa base so I guess it,s just not a perfect world after all.

Sounds like i will be good to a 1000yds. Great!!!!

Thanks Every one

er, uh, my action is a Large Ring 1912 Steyr Mauser. I wonder ??????? 8)

 

[longbow]

If you can sight in at 30" below bullseye you will hit 1,000 yds with 6 dasher with 105's and 31.5 gr RL 15 ....no problem!
So with white butcher paper draw a straight vertical line 30" put an X at top and X at bottom of the 30" line at 100 yds you are aiming at the low X , your bullet needs to hit the top X. you will be on paper at 1,000 yds.
If you dont have any more elevation you need to shim the scope base. We only use the Burris with the plastic inserts go 0-20 on rear and 20-0 on front, what you want is the focus on your scope is about dead center at 1,000 yds then you have plenty od elevation up or down. Hope this helps....this is the standard to sight in at 1,000 yds 6 Dasher, etc. Pete
