6.5 CM load data using 143 gr Hornady ELDX

Don't have a way to send the pic (no scanner), but I can give you a QL projection.

Code:
Cartridge          : 6.5 Creedmoor Hornady
Bullet             : .264, 143, Hornady ELD-X 2635 G7
Useable Case Capaci: 46.285 grain H2O = 3.005 cm³
Cartridge O.A.L. L6: 2.800 inch = 71.12 mm
Barrel Length      : 24.0 inch = 609.6 mm

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 62350 psi, or 429 MPa
or a maximum loading ratio or filling of 112 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.
USE ONLY FOR COMPARISON !

7 loads produced a Loading Ratio below user-defined minimum of 90%. These powders have been skipped.

Not a matter of intelligence, but an explanation is in order. Perhaps this will help.

After the powder is listed, the first column is the loading ratio (amount of fill for a given powder). Then, the approximate maximum charge is listed in grains and in grams. After this is a column with the anticipated maximum velocity in a 24 inch barrel (in this instance). Then you see a column giving the percentage of powder burned. Then, you have a maximum chamber pressure, followed by a maximum muzzle pressure. Finally, there is a time for the bullet to clear the barrel in milliseconds. This allows you to choose what powders to use on the basis of charge volume or anticipated velocity or barrel time.

I set up the chart to provide the powders in descending order from the highest anticipated velocity to the lowest.
 
Here's the page from Hornady 10th.

I had stellar results with a max load of Superformance.

Followed with heavy crunching of powder I bet.
I bet it’s pretty compressed lol. People have been getting some insane speeds and accuracy with RL26. Really makes me wanna try it.

Interesting to see ( during load developments ) if you measure your first charge of your first compressed 3 loaded rounds and the last increased charge of your last 3 compressed rounds, you can see the different COAL , try measuring each of those different 3 groups of loaded rounds and see your COAL increase, lol. On the .308 with the 10 inch long drop tube with the IMR 4064, I see each .3 grain incremented round measures an additional .001 -.002" in COAL. It's hard to keep all the rounds on the same COAL.

Man, it is hard to believe 26 will work in that little Creed.. That is pretty darned interesting.

Followed with heavy crunching of powder I bet.
I bet it’s pretty compressed lol. People have been getting some insane speeds and accuracy with RL26. Really makes me wanna try it.

Interesting to see ( during load developments ) if you measure your first charge of your first compressed 3 loaded rounds and the last increased charge of your last 3 compressed rounds, you can see the different COAL , try measuring each of those different 3 groups of loaded rounds and see your COAL increase, lol. On the .308 with the 10 inch long drop tube with the IMR 4064, I see each .3 grain incremented round measures an additional .001 -.002" in COAL. It's hard to keep all the rounds on the same COAL.

Sorry to be off topic Guy.
Absolutely! I ran into this issue stuffing IMR 7828 behind a 140 when I owned a 260 Rem. I know that seems an odd powder choice but it shot great lol.

Thanks for the explanation Dr Mike and thanks to hodgeman for the page pic.

If you guys had to pick ONE powder which one would you try and why?

Trying to be as efficient with my load development as I can

There are a bunch of great powders for the 6.5 CM. My favorite though would have to be RL16. Reasons being I get great accuracy, speed, and temp stability. But those are also the benefits of H4350, IMR4451 too. RL 17 has been extremely accurate fo me also, but lacks some in the temp stability department.

Thanks...was looking into superformance. love the speed and unlike H4350, which I have better chance of finding a unicorn nowadays, seems to readily available.

thoughts?

I fired 4 different SuperP loads each with 3 different bullets- 129SST, 130AB and 143ELDX. Everything loaded to book OAL so no messing with seating depth...just varying charge weights. It favored charges toward to heavier end with all bullet weights.

Everything was "hunting grade" accuracy at 1.5" or smaller and a max load behind a 143ELDX was a 0.546" group. I just simply can't shoot any better than that. Max charges behind both the SST and AB were a little under an inch. The SST load had a slightly stiff bolt lift, but no additional pressure signs.

I like the way it meters and it was very easy to get consistent charge weights. I've done limited load development with it in other cartridges, but in the 6.5 I couldn't find anything negative.

I'm trying it in my .300WSM with the 165AB soon and trying both the 6.5 and 300 loads over a chronograph once it warms up a bit.

H4350, its so consistent and works very well, but hard to find.
 
H4350 is a great powder, but so hard to find a supply of it nowadays. I’ve had great luck with RL16. Also hear IMR4451 is a great replacement too, but I have yet to try any out myself.

I’ve never tried superformance, but I’ve heard good things. And your right superformance is always on the shelf!
