New 4 oz. AIR BRACE Cantilever Mount, American Rifle Company Black Friday Sale

Hi st1650,
My quest for this 1-mile shot has totally enthused me to the point where I have to learn something every day. I am glad that you are at Snipers Hide. This site is exactly as my buddy told me.

I'm buying him and you guys (6.55H ** (It's an honor Sir)) and st1650 ...I hope you keep coming after me and (Glassaholic ... I saw the list of your reviews) a steak dinner at a great restaurant. Find me and you're in. LOL

st1650 I worked hard for that zero by actually using a T-square and level to position my target for the zero. I used the Razor 4000 GB in Horizontal Component Distance which is angle compensated distance to a target. I worked hard at that zero However Razor gave me 93.8 and Kestrel only takes integers. I shot approx 10 shots just to warm up for the zero. (It was 36 and windy) then I put 3 rounds with one-hole elliptical circle. Picture attached. I went in the car to get warm and shot a 4th elevation was up a smidge but windage was dead nuts. I was proud of that zero for thoroughly but now that you questioned it .... I should have gone to the adjacent 100 zeroing area at used a perfect number at 0 degrees angle. So, there goes that zero (freezing cold) zero. I was an embedded software/hardware engineer for 25 years and I know about building a foundation design so that other programmers can write apps that use my stuff. If my stuff isn't right, I would cause all the software above my level to fail or glitch.

About using this big offset on my zero, It started when I used a ballistics calculator and the kestrel and I need something like 140 MOA to make the mile shot. I have 100 MOA of adjustment in my scope. So, I read and researched about not having enough adjustment and the common methods were basically cant your scope as much as you can and hold under for your zero. As far as the Kestrel and Vortex and applied ballistics or geoballistics I think this offset is just a number like any other number to the software (I HOPE!!) I had to deal with that ridiculous issue with 2k and the year didn't have enough memory to store a number past 1999. I am also worried about the software dealing with negative numbers. I'm just going to have to test as much of the elevation as I can.

I fully understand your view about this crazy offset. I am going to test the kestrel by setting the weather values to 70 deg like what I was shooting in before we got the crazy numbers that happened on last Wednesday (for myrtle beach).

When I put the kestrel and Vortex feeding the Geobalistics app, it gave me 4.5 MOA and there wasn't much wind. I shot the first round aiming at the bolt that holds the steel target against the stand at 500 yards and hit it. Also, until that freezing cold day, My elevation values have always been spot on. I guess I just can get past the possibility that 36 deg screwed me up. I film all my tests and glad to share anything you ask me or show you what I have done so far.

I do plan on getting an accurate 22 and a round that applied ballistics created a curve for. That will give me a chance to get elevation right thru transonic and subsonic. I'm just trying to remove as many variables as possible before I return to Coleman's Creek long range shooting.
 
I have been looking around Snipers Hide forums and I have realized I should get off this subject that actually is about North American Rifle company’s new Air Brace.

I apologize to ARC (whom I pestered with questions about the 55 LBS torque settings) and now I hijacked your Thread .

By the way American Rifle Company, this scope mount is just beautiful and it is the most mistake-proof mounting process I have ever seen. ESPECIALLY using T 25 screws for everything. I couldn’t strip those screws even if I was wearing oven mittens.

I want to start my own thread and call it my 1 mile journey at 68 years old. But I have to admit, I don’t want to risk you three guys not following the thread. Please tell me what to do.

I also have a question, if I upgrade my membership from the level I just did yesterday to the one that includes everything, can I back it back down to the 19.99 /month membership after I (with God’s grace) shoot the mile.
Thanks for reading!!!!!
 
Hello st1650, had some stuff to take care of that sidetracked me. BOY O BOY WERE YOU RIGHT!!
All I can say is I meant what I said about being a good student.

I just got back to work on where we left off about Zero Offset being a large number. I looked at your background and knew the first thing I need to do is prove that the kestrel can handle it. I never liked that the Kestrel would not take 93.79 yards for zero distance and chopped off the fraction.

Then I wondered where else is this Kestrel chopping off remainders because there's no way a kestrel has a powerful math chip in its hardware. So I started looking and found this. But I don't consider 1.5 MOA at 500 yards small unless its a flintlock rifle.


Yes, while the Kestrel 5700 Elite is generally considered very accurate, there can be a potential for slight inaccuracies when selecting a large zero offset, particularly if you are shooting at extreme ranges or with significant environmental changes, due to the increased reliance on ballistic calculations and the potential for minor errors in input data like bullet coefficient or wind readings; however, this is usually a negligible factor for most shooting situations.

Key points to consider:
  • Large zero offsets and long ranges:
    When you set a large zero offset, the calculations required to compensate for bullet drop become more sensitive to even small variations in wind speed, temperature, or other environmental factors, which can lead to slightly less precise results.

  • Importance of accurate input data:
    To minimize potential inaccuracies, ensure you are entering the correct data for your specific ammunition, including bullet weight, ballistic coefficient, and muzzle velocity.

  • Field testing and adjustments:
    Even with a Kestrel Elite, it is always best practice to verify your zero at various ranges and under different conditions to fine-tune your settings and compensate for any potential discrepancies.

Sorry about that Sir. I guess my background can be a disadvantage when thinking too much. It does make me wonder what this AB solver actual calculation or the Geo ballistic solver. Is there any way that can be viewed????

I just Today after getting 338 an 50 ready for Coleman’s FINALLY found a huge screw up on my part. When I started looking at everything I changed since I switched scope mounts to ARC 60 MOA cant. I failed to update my scope height to the new 3.33 inches. It was 2.5. I had to put a picatinny riser under the mount because the scope was bottoming out on the rail. I’m gonna get started with the 308 and first I’m gonna try the is the Ammo suggested and hope my gun loves the Federal 185 Berger.
 
Mine arrived rather suddenly last Thursday. Got the notice on Wednesday and it was in my hands on Thursday. If y'all sent it overnight, you certainly didn't have to do that but I do appreciate it! Haven't used it yet but color me impressed, really nice build quality. The bolts look like heat treated titanium even though I know they're stainless. Now I have to decide what rifle/scope to use it with or do things properly and get a new rifle and scope to go with the mount.
 
i have one in the 30mm 20 moa variety and its the standard ARC quality. scope doesn't move at all when you clamp the rings down. level is perfect and the new colored screws are cool.

Big upgrade to the old ARC QD-L mount I used for years on my AR.

But I miss the QD-L thumb wheels, Ted mentioned early in this thread that would be coming, still waiting for that @karagias
