Reloader 26 in 6.5 creedmoor

[ifgator]

What are the fired cases measuring b's the loaded case going in the chamber

Sorry sir I'm not sure what you are talking about. You can talk dumb to me.
I'm having birthday dinner but I have one wildcard. I'll also post my measurements.
Thanks

Measure just above the rim at the shoulder and overall. Should have been vs. I'm on my phone and autocorrect does a number on what's going on

Ok I need help. I used RL26 in my 7mm and it was super simple. My 6.5 CM is killing me. I have smashed primers no matter what. I have quickload and nothing is matching up as I'm seeing pressure when I think I shouldn't. I'm too frustrated to read this thread right now but please have mercy on me as I'll put everything out there and come back when I'm not crazy and read it with a cool head and hopefully if I missed something obvious you guys can tell me.

I have a semicustom rifle I guess you would call it. 26" 1-8 twist Bartlein.
140 grain Berger Elite hunter, new Nosler brass. 210 gm primer.
Coal 2.875 and 20 off lands
Case length 1.905
H20= 53.00 grains actual was 53.3 but being conservative.
So QL shows my max load at 50 grains as the last near max warning.
Anyway I've tried some loads and today I loaded up 45.0 grains convinced I would be fine. Nope. Completely smashed primers. No lip but as smashed as it gets.
QL says my pressure should be roughly 42,227

Check Your burn rate to your powder....

Again forgive my ignorance. I realize you can fudge the numbers. In someways I was so far off on velocities it's not an easy adjustment.

So do you want the case size differences between unfired and fired? I realize you said just above the shoulder. Maybe a pic or a link?

Okay here are my measurements and also a possible curveball. I've used the Hornady OAL tool AND I've also used a fired brass and dented neck very slightly to give resistance and then marker on bullet and use my bolt method. Same numbers. Here's the wildcard. My gunsmith gave me a piece of my barrel and it's chambered I guess you might call it so it's a quick way to measure dummy rounds with different bullets. Anyway I am crazy cautious to not jam the bullet into the barrel nut or whatever you would call it. I probably measured 50 times and I kept getting COAL: 2.925.

6.5 CM Berger 140 Elite, Nosler, GM 210,
RL26, Bartlein 26" 8" twist
To lands
COAL: 2.895
OAL: 2.222
H2O: 53.00 once fired Nosler brass
Case: 1.905

Test 20 thousandths off lands
COAL: 2.875
OAL: 2.202

Measure the diameter above the groove your extractor grabs. About a 1/4" up do the same place on a unfired case.
You may have a fast lot of powder like stated. Your using 210s which are very soft cup primers. Wolf primers may cure what your seeing
Are you getting shiny spots on the case where the ejector and extractor arr?

Sorry I haven't got back to you as I appreciate the help. I'm a a lot beat up right now. I will recheck for those marks and at what charges. I'm working on 3 rifles right now and don't want to give bad info. I do know I haven't had difficult bolt lift on the rifle we are discussing.

Doing some loads with R26 for my first range day with the new build 6.5 Creedmoor...I've never loaded anything that has powder in the neck of the case before seating a bullet.

This is kind of spooky....

I'm loading 47.5 gr of R26 into Hoready 308 brass that I've trimmed and necked down. I wanted some brass with a little more durable neck because that' a normal failure area...but I'm not sure about compressing powder!

You guys feel fine about this?

Use an electric toothbrush on the side of the case while the case is in the loading block. It will settle the powder below the neck. You can watch it do it. only takes a few seconds. Easier than using a drop tube.
Add: I use the backside of the brush, not the side with the bristles.

Thanks B...I did tap on the case to settle the powder some but it still looked iffy. So I primed some 6.5 CM brass and transferred the powder. It is below the neck in dedicated 6.5 CM brass.

It appears 308 brass has less capacity...I learned about using 308 brass on Accurate Shooters forum. It is pretty spooky to have that much powder in the case.

I felt the same way when I stuffed in 49 grains and it was halfway up my neck!

 

[Creedmoor shooter]

I just got in my 500 sleeve of the 147s. I had a good node at 48 grain s with the 140s. Im planning on running 46.5and 47 to start to see where that gets me. I'll report back my results

 

[Earnhardt]

I justed started setting up loads with RL-26 in my 30" Creedmoor.
I've gone up to 48.5 grains with the 140 ELD's, and 47 grains with the 147 ELD's.
With either the 140's or 147's, is there a lower end pressure that I should stay above, so the RL-26 burns at max efficiency?
Yes, I have Quickload
Thanks

Do we feel fine about this as in is it going to blow up upon seating a bullet? no. Will it blow your rifle up? If you put too much powder in it, it will. I have loaded many many loads that were crunching powder as I seated bullets, the .223 with H-4895 comes to mind. Literally thousands of rounds loaded with a stiff load of H-4895 under a 40 grain v-max, never an issue. And compressed as in the powder was level with the top of the case, not the neck shoulder junction, the case. You could literally scoop powder up and scrape the mound off the top with a butter knife, and it would look the same. Then, crunch a bullet on top. And this was not a max listed load in the manuals, about .5 grains under max actually.

Where you may have issues with compressed loads is two things. One, it is compressed enough that you cannot get consistent seating depth, as the pressure from the powder isn't the same every time and it will vary several thousandths. The other, and I believe these can be related, is large E.S. numbers.

So would I be concerned with compressed loads? Not if it isn't an overpressure load, of course, watch for signs. But if you can avoid it, it seems best for consistency. I use a 6" drop tube to load 49.1 grains of reloder 26 in my .260 AI, the the base of the bullet just touches the powder, no compression.

I never liked compressed loads and avoid them. A slightly compressed load is livable but other than that I'd just as soon use a less bulky powder.
