How about those primers? OK pressure?

 

I'd say it's fine, while cratered the radius on the edge of the primer cup is still smooth and round.

To OP:

Did you measure case head expansion after firing?

 

Okay I'm interested in seeing .223 at a mile.

Now that you got a load are you going to take mv and temp measurements to start range cards with?

 

What was the distance in these preliminary targets?

 

Thanks for posting and sharing. What distance is that?

 

What's the twist rate on your rifle?

75gr is a bit light for that range ... why not use the 80 or 90gr pills out there?

Not trying to create a flap here ... I'm really curious as to your thinking.

 

:yeahthat:

 

why did you seat the bullets in the field and not at home? It seems there is a risk of spilling out some powder while in transport?

 

It saves on components. If you find a powder charge that is out of the running (using the ladder like he did is a great way to develop loads) you don't have unfired rounds you need to dissemble to recover components.

And pulled bullets risk jacket damage.

It makes no sense shooting a full 10 rounds of something that won't be up to spec. Why waste the components and put the wear on your barrel.

So put a piece of foam over the bullet mouths (and don't drop your ammo box) and you won't spill any powder.

 

Great shooting/loading!
the link is to a good article on shooting .223 @ 1 mile so you aren't the only one who gets the blah, blah, blah. LOL!

Load testing was done at 300 yards

 

Impressive at that distance. :bthumb:

 

Wow, that Jerry Teo is amazing!

Being able to hit a prairie dog at one mile is pretty incredible, even more so with a .223 Remington

I'm sure the US Palma team and USAMU team armorers will be contacting him as he just threw together a rifle with OTS parts that shoots significantly better than what they build for our Nations competitive teams and our military's snipers! Is he the future Stradivarius of rifle building? One hopes he doesn't take him mojo to the grave like the great instrument builder, the world will be a lessor place if he does..

I can't wait to see this guy sweep highpower matches all across North America. Oh shucks, there's one small problem. You don't see his name on the match bulletins of any NRA sanctioned matches, I guess modesty keeps him from wanting to beat the past champions too severely ...what a guy.

And as an avid photographer that has spent many thousands of dollars on individual lenses, I want to know how he used digiscoping to push beyond the physical resolution limits of optical glass to capture the film that he presents as evidence. I'd love to dump my high end Nikkors (and quickly before this news gets out) and replace those lenses with a spotting scope the costs 1/5 the price. Oh yes ... he has mastered the time / space continuum too, warping time Einstein has been vindicated!

Okay ... I'm sorry for the snarky post. But, this "article" has been out for a long time. Many have asked him to enter the rig and shoot in a sanctioned match to show what he can do. The author never has. Neither has he ever agreed to repeat the experiment in front of other shooters. The responses to his article have been strongly edited, nothing but positive posts are shown, and quite a few folks have challenged him through the site to repeat his feat. He answered with some vague excuse that he's a hunter not a competitor but that I see has now been removed.

Don't get me wrong. I have nothing against 1mile shooting, and I applaud the OP for running this experiment. While it has its limitations (part of the fun of it I say) the .223 Rem can and is used in LR completion (LR, Palma, F-class (T/R)) and in the right hands is remarkable regarding what it can do. Throwing another 760 yards into the mix and doing well is astounding.

What gets me is that a bloke like this tosses around the idea that this is simple and can be done by throwing together a low end rig and throw together a load and he can then hit his targets with routine accuracy. He diminishes the efforts and skills of those who can actually do this type of thing. Shame on him.

Enter a long-range match, and let your score speak for itself. To the OP, don't be discouraged when you find this much more daunting ... keep at it. I for one am interested in your results and the fun is as much in the trying as in the doing when you take on a task like this!

 

Here are the "extra" ones, dumped the powder back in the charge master and loaded to 23.2gr



Go right for a mile... or shoot a few groups at 1000 yards first?

 

I'd go from 300 to 600 then to 1K. There is a lot of data regarding come ups from 600 to 1k, as those are commonly shot distances. From 1K I'd march it out from there considering your range, conditions etc. Perhaps go 1300, 1500, 1760? Each addition to distance will be exponentially more difficult.

Or go for it and jump right to a mile if you don't mind launching a lot of rounds into never never land! LOL

Going out too far too fast will waste the components you worked so hard to save, if you get my drift (yeah that was a really poor pun for a LR shooter).

How are you planning to measure the range to your targets and how are you planning to spot your hits?

 

I'm still curious as to your rate of twist and why you chose 75gr bullets over the more commonly used 80 or 90 grain projectiles.

Do you mind sharing your thinking?

 

Thats what I have on hand...

Rifle twist rate is 1:7

 

Do 1000 first, that is unless you and conditions feel a really good day in the makings.

How much throat, and with .015” jump where ~ is the base of a 75 gr. Hornady HPBT in relation to the neck/shoulder junction?

I’m thinking on how to go about doing up a .224”-204 capable of lobbing up to the 77gr. SMK, though well short of a mile.

 

1k to a mile is a big jump, it's several factors more difficult than the jump from 500 to 1K. But hey if you can do it Kewl!

How much wind adjustment do you have on your scope? My Redfield Palma sights that sit on my belly guns has a total adjustment of 36 minutes. There are times that is not enough and you have to hold on a neighboring target's bull to be hitting your target. A 10mph full value wind will often require this a 1K. I haven't run the numbers in a calculator, but I'm betting you would have over 20 minutes of correction at one mile.

I bring this up because as you set your target at 1 mile, you may need some aiming points to the upwind side because I'm betting you probably don't have more the 20 minutes of real wind adjustment on your scope. While the reticule may move farther, you begin to suffer from optical issues when it is at the far edge of the viewing field. Just some ideas that may help you.

Let us know how it goes!

Pest here: Still curious as to your twist rate and why you are using such light bullets for this test? Again, I'm not trying to find fault at all. I'm wanting to know your thought process, and perhaps learn something along the way.

... hmm, y'know....he did answer your question.
Scroll back up a few.

 

Great thread. Thanks for sharing clayneb :bthumb:

 

Went out today to do some load work with the 6.5 Creedmoor,

Here are the first 6 shots out of the 223 at 600 yards

I colored the impact points with a marker so they would be easier to see

 

Will my husbands Ruger American in .223 be capable of that kind of shooting?

Amazing shooting. What is your creedmore config?

 

Savage 12 LRP, SWFA SS 5-20x50 HD

 

That explains it. I don't own a savage but I hear they are one of the most accurate out of the box rifles today. I was on the fence between the Savage 12 and the Remington 5r. I did alot of research and decided on the Remington in 308. I only have access to approx. 500yds at this time but I am addicted to the accuracy potential of these guns. I dont have the gun yet (layaway) and still planning the glass factor. :bthumb:

 

That's a very nice 600 yard group.:bthumb:

 

While I do like the American Rifle's Ruger has come out with, a sub half-MOA grouping out of one is a stretch. And that's for 100 yards. Out of the box I have read a lot of people getting anywhere from .75''- 1.5'' out of them at 100 yards. With some reloads that could tighten up a little.

But definitely not to the degree you see in the above picture. If you want that sort of grouping at 600, you'll need a rifle more suited to long distance shooting and a LOT of training/practice.

 

Thank you for the informative post!

Great shooting. Tac is great powder. Use lots of it. Great in 308 too.
