Help Update...with a mile 6.5 Creedmoore ?

Closeone

New to the bolt gun....been dealing with the AR platform for 30 years. Planning on going for a mile with my 6.5 creedmoore tikka t3x tac A1. Optic is a vortex razor 5-20x50 in MOA, around 125 moa in the turret. 140gr Berger Hybrid, 2815 FPS, I’ve installed a 20 MOA rail on the rifle. Strelok says I need 77 moa for a mile...question is do I need more moa in the rings or not? Thanks in advance for any help....Up Date More info. the shoot will be taking place on a range where I’ve seen it done before w/ a dedicated spotter. Same tikka rifle, same caliber, same elevation 676, They were using a hornady ELD. The Berger I’m using (Copper creek) has better ballistics.

You have 125 MOA left on elevation with your 100 yard zero?
That would be phenomenal as Vortex specs TOTAL 125MOA elevation and you must remember that any windage adjustment for zero could take up some of that elevation. Maybe, just for the purpose of a one mile attempt, you might put that scope in something like a 20MOA Sphur or even a AI canted ring mount.
Beginner's luck beats know how every time. Go for it! ;)

Howdy @shoot4fun. I’m not sure I understood your point about the windage. Are you saying if you dial say 20 or 25 clicks for wind that you won’t be able to elevate as much because you moved away from the center of the tube, or is it something else? I never ran into this issue because of using gridded reticles and just holding for the wind.
 
If your scope has 125 Moa using the turrets and you are using a 20 moa rail you should have approx 82.5 ish Moa dial up give or take how your 100 yard zero went. That being said if you need 77 moa to get there you should be able to make it but you will be maxed out or very close to it.
 
At 676 ft, you’ll most likely be having some bullet instability. Your hit probability will be low, probably single digit percentage on a single shot, but it depends on target size too. A four by eight sheet of plywood (positioned 4 high by 8 wide), a good spotter (not just a spotting scope, I mean another shooter using a spotting scope), and about half a box of ammo would give you a good chance. Good luck.

Any scope is mechanically limited by the total amount of allowable movement internally. That is, unless these engineer types have figured out how to get around it. The larger tubes are not just to "gather more light" as we were told. It's how they, along with high tech machining of the innards, get the numbers they spit out in the specs of optics today.

How big is that box of ammo to start with?:cool:
 
I've done it with a very similar setup. Razor Gen 2, 30" Creedmoor barrel, 140 Hybrids etc.


It's been about 1.5 years since I did it, so the memory is a little hazy, but IIRC I ran out of elevation and was holding over via the reticle. You would probably want a 30-40 MOA base or mount.

You will need wind flags. A lot of them.

The place I was shooting didn't have them, and you were shooting over a large valley to the mile target. What I do clearly remember is:

1.) Having a lot of trouble spotting dirt splashes,
2.) The 6.5CM/140 hybrid combo just doesn't have the horsepower to do it effectively. Some of this was due to the lack of wind flags, but you'd get the rifle impacting somewhere around the steel plate, and then a wind shift (that you couldn't detect) would throw you 8-10 feet (or more) off target.

I have enough trouble staying in the F-Class X/10 ring at 1,000 with just about any caliber. Regularly shooting a mile with a 6.5CM (regardless of bullet weight) is a little too sporty for my tastes.

I suppose it would be fun if you had something that resembled a highpower range, with relatively calm winds, and flags down either side. Still, with any level of wind, you're going to get blown all over the place, and spotting your hits/misses is going to be very difficult.

Not trying to talk you out of it; just trying to help with expectations.

Good luck!

Edit: Forgot about the stability aspects of it. Regardless, I remember being on target one shot, and 10ft left/right/high/low the next; this barrel runs them into under an inch at 300 pretty routinely...not like it's an inaccurate barrel/load combo.

I love my tac A1 in 6.5 creedmoor. Still shooting the factory barrel that gives a consistent 3/4 MOA. Although it is slow compared to my other 6.5 barrels, it still shoots great. I don't believe you will need any extra MOA in the rings. Can't guarantee it, but on my 6.5's that I have ATACR's on, I usually get about 2-3 revolutions after a 200 Yard zero (30MOA per revolution) and 20 MOA rings. And my scope reticle gives another 20-25, So i have around 80-100 MOA. I don't think you'd have an issue, but I would go and double check by zeroing at 100 yds and then just see how many times you can turn it. Don't expect the tracking to be perfect though past 30 MOA's. A rep once told me they can't guarantee there scopes will track consistently passed 30 MOA's. But have fun and let us know how it goes. I've always wanted to take mine to a mile, most I've taken it to as of now is 1100 just because I don't have easy access to a mile.

A guy was able to get to 1 mile in a 6BRA with one of our 50 MOA bases atop his 20 MOA rail (70 total, I think). There’s a post here about it. I’ll see if I can find & link to it. @Dave Way
 

A mile, just for fun

So I had been dying to shoot a match since early spring when I heard about the 1K GBA shoot at Thunder Valley in Ohio. I decided right away I was going, but then I just had to go and hear they were also shooting a mile... The next thing I knew I had ordered a F&C 60 MOA rail to mount to my...
forum.accurateshooter.com

Correction, he was at 80 total.
 
If a 45-70 can hit at two miles, I am sure a Creedmoor can do one.

I would suggest using a very fast for caliber twist barrel to help stability and BC in this endeavor.
