Need 6.5 Creedmore Loading Data

[Revelation]

Anyone have any really good loading data for the 6.5 creedmore ??
Thinking about doing some hand loads so I thought I would see if anyone has found the magic load !!!
PM if necessary

Thanks !!!!

H4350 40-43 grains 140 grain bullet, that should be relatively close. I use that data for a .260 rem. Work up to pressure or desired accuracy.

What bullet are you wanting to shoot? And what case? H4350 and Reloder 16 have been great powders for me and plenty of others.

I had a decent variance in powder charge between Hornady and Starline brass cases, so just something to watch out for, depending on what you plan on using.

I use IMR4350 and 143 gr. ELD-Xs with good success.
I've got Bergers, Barnes, 4831 & Varget to play with.
What works in one rifle may not in another.

I am surprised to see someone else used imr4831

I’ve used it as well with good success.

Close the thread after that response. Find your accuracy node using a Satterlee test, then tweak the seating depth. Done in 30 rounds.

I had a great load with RL16 and the 147 ELDM. Dont have my book but was around 2750 with low PSI so great brass life and less wear on your gun

Yup. I’ve got 2 260rems and they both like 4350 with a 140, one likes a light charge on likes a stout compressed load.

The 260 case is noticeably larger capacity than a 6.5 Creedmoor, I would not load that much H4350 in a 6.5 Creedmoor. The Creedmoor has a case that seems to be based off of the 22-250, as where the 260 Rem. is basically a necked up 243, both of those based off of the 308 case. The 6.5 Creedmoor has a more efficient design case, but definitely smaller case capacity than the 260.

37-40 H4350 is what my manual says. I’d say start at 38.5 and work to pressure or accuracy.

Anyone have some Hornady Black factory ammo they can measure the base to ogive length for me? Trying to duplicate that jump for some Berger match burners.

I have been working on some 140 gr. loads for my Creedmoor. I found a load that looked pretty good for Reloader 19. It fills the case better than most other loads and also of all loads I saw listed, produced the highest velocities. But they did not list what case they used to get those numbers. Lapua makes a 6.5 Creedmoor case, that has a small primer pocket, which allows you to load the round a little hotter, not a lot hotter. So in the load data I found, for Reloader 19 with a 140 gr. boat tail, it showed 43 gr. being on the low end and 46.5 gr. for max. I have been working on loading Reloader 19 in my Creedmoor, I have the Lapua cases. So far, with 140 gr. Nosler Accubonds. It only wants 43.5 gr. of powder. Not sure what bullets and cases they used, when they loaded 46.5 gr of Reloader 19. At 44 gr. of Reloader 19, with CCI small magnum rifle primers, I am starting to see signs of high pressure. With Remington 7 1/2 primers, I was not liking the looks of the primers at 43 gr. With 43.5 gr. with the CCI primers, I think they are the 450s, they look good at 43.5 gr.

I have not shot through the chronograph yet with any of these loads. My gun has a 24" barrel and the throat seems to be fairly deep, so I have the bullets seats quite a ways out of the case. Not sure the normal depth of a 6.5 Creedmoor throat. The Nosler Ballistic Tips and Accubonds are pretty long for their weight, I have the Accubonds seated quite a ways out of the case, to get them .030" off the lands. If other guns don't have as deep of a throat, the bullet will need to be seated deeper, which will take up case capacity. Which will reduce the powder capacity/ bump the pressures with the same powder charge. So the powder charge I am using, likely will not work well in other guns, but with shorter bullets, such as a Sierra Game King, you will likely be able to load more powder. There are many factors.

I am not sure of how deep common 6.5 Creedmoor throats are, not sure if they typically are very deep. When I first figured out how deep the throat is in my gun, I wondered if someone had reamed the throat out deeper to shoot longer bullets and or increase the overall length, so they could get more power in the case. That is something I am curious of at this point. I have loaded some Berger 140 gr. bullets, with the bullet just touching the rifling lands, the overall length of the round is 3.023".

There are a lot of other bullets, powders and there are multiple case options. I just started off with the Lapua cases, since I discovered them for another caliber gun I have, that is a wildcat based off of the 6.5X47 Lapua round. So most everybody that loads that round uses the Lapua cases, because you can load them a bit hotter, it helps those cases that have very small case capacity. So when I found out that Lapua started making small primer pocket Creedmoor cases, I bought those and started with them. Then also Lapua cases are very good cases, they are expensive also.

Hopefully this weekend, I will have my chronograph app loaded on my current phone and take the Creedmoor out and shoot it through the chronograph with both the Accubonds and the Berger bullets and see how both do. Then work on seeing what seating depth the gun likes with the Berger bullets and also work on the seating depth with the Accubonds. I did not experiment with the seating depth with those, just went with .030" off the lands and started loading. I am really curious of what this gun will do. Hopefully I can get it to spit 140 gr. bullets out the barrel around 2900 fps. With the 24" barrel, Reloader 19 and the Lapua cases, I should be able to, just not sure it will happen, when I had to cut the powder charge back by 3 gr. It should be well into the 2800 fps range with both the Accbonds and the Berger bullets. Hopefully this weekend I can start getting farther along on my loads for this gun.

At this point, I have no experience with any other weight bullets, other than the 140s and have only tried the Reloader 19 powder. I think 4350 was one of the other powders I wanted to try, but did not have any, but have plenty of Reloader 19, because that's is my favorite 7mm Rem. Mag. powder. I am working on getting this thing set up to do some longer range mule deer hunting.
