The creedmoor has gotten a huge following and I know quite a few members here shoot 6.5 and load for it as well so I figured why not start a thread dedicated to the caliber and get a bunch of info all in one spot. So post up your rifles, pet loads, tips & tricks, show off your groups, whatever!
 
Tonight I checked max OAL's for my HMR with Hornady 140 eldm and 140 hpbt match. Curious how it compares to the throats in other people's rigs.

you now have 1 like, I'm watching this thread...... I want my next rifle to be a 6mmBR or a 6.5 Creedmoor.
 
Im not sure if it's the thread they dislike or the creator? ;)

I'm prepping brass as we speak for my 140bthp load tests.
you able to shoot sunday?

Well seeing as I've only met a few members, the rest haven't been blesebl with the opportunity to love me yet...

I was hoping to shoot one day. Depends on if I get that load worked up. Need to go get CCI 450's in the morning.

Do you happen to have a headspace measurement on your once fired brass? Looks like mine stretched .004-.005" on the first firing. Not sure if that classifies as a tight, normal, or loose chamber as this is my first precision rifle. I see most people bump the shoulder .001-.002" so should I bump what I've got or shoot it again and then bump it back to where it is?

I measured when I had once fired and new brass, I forget exactly what it was but I believe it was very close to what yours did and I just set my sizing die up where it bumped it back .001 i believe. Now Im going to have to go buy a box of ammo tomorrow so I can shoot some new and compare it lol.

I still havent got a time for sunday, Ill let you know tonight or tomorrow.
 
.020" seems to be the standard jump for the eldm's. Where I will start as well. Gonna measure the few American Gunner rounds I have left to see how far they've been jumping
I hope my stuff does good sunday, I hope to have good luck with the BTHP loads, it'd save me some cash for sure. But For hawks ridge, Ill probably load up 100 rounds of the ELD to use there.
 
I'm really having fun with my 6.5CM. Shoots like a dream and has given me the opportunity learn the "precision" reloading game.

I posted this in the Precision Rifles thread, but I'll brag again....my best group to date is this 4 round 0.428" / 0.22 MOA effort at 200 yards last week.

Awesome!! I am also learning precision reloading on this platform and can't wait to see how it goes. How much are you jumping your eldm's?
 
Check out BulletCentral... they have the good prices... but these have been hard to find... they have become literally the magic bullet.

I have noticed that but with me being new to this, I don't understand the reasoning for all the hype. Can you enlighten me?
 
So just out of curiosity I just measured some factory Hornady American Gunner (140 hpbt) and some factory 140 eldm and in my rifle they are jumping .080" and .096" respectively. The American Gunner printed right at .5" at 100yds and that was literally the first rounds through a brand new clean barrel. The eldm was just under 1".
 
700 yards 6 shots 3.3" or there's about.

God's gift to man H4350 and 140 hybrid. Hybrids can jump a mile and not care. Back up is a SMK...not a as much BC as a hybrid but still just as accurate.

Okay, let me hit you with some guess work, cause I really don’t know anything.

Did your fired brass extract easily? If you put it back in the chamber will the bolt close easily? If yes to both then neck size and fire it again. Repeat until you get resistance working the bolt. Now bump the shoulder back .001 and see if the resistance is gone. If it is then you now have a good length for your chamber, if not then bump it back again and try again. Once you have the length down then full length sizing after every firing should be bumping the shoulder back around .001-.002.

Again, this is based on reading stuff on the internet and ideas that make sense to me...it could be crap.

Your rifle is chamber to a sammi spec. You can't determine headspace off a price of brass. The brass (most of the time) is size on the small size of the sammi spec and the brass when fired will be fired form to that chamber. This is why when reloading precision rifle guys will bump the shoulder 0.002-3 back. This gives room for environmental (dust, water,etc) in to the action to not have a stoppage. Also it allows more energy to propelle the bullet vs during fire forming energy is wasted expanded the case out until it hits the chambers wall. Even my chamber competition rifle above is the same way. Shoot new brass, bump it back 0.002 and reload.


Don't worry about neck sizing die. Get a FL/Neck sizing with the correct bushing or go with a forster die and you can still bump the shoulder back. When setting up the die, the case will grow first in lenght before it starts to shrink.

IE if the case is 2.125 you'll see it go 2.130-35-27-24

So trying to setup my sizing die. Most of my brass is showing 1.541" from base to shoulder datum line using the .400" comparator in the Hornady tool. I do have some showing 1.539" and some up to 1.543". The 1.543" still Chambers just fine. Which length do I use to set a .001-.002" bump?
 
I'm getting my measurements off hornady once fired but plan to load starline small primer. The new starline is measuring 1.535". Should I just uniform the case mouths on them and see where their shoulder ends up after the first firing then bump that .002"? Guessing they will end up the same as the hornady

If you don't see a hole, sharp crease or crack, shoot it. The dent will most likely flatten out the dent when fired......if not, toss it. If it works out, mark it just to keep an eye on it. I have caved the shoulder in on cases from over lubrication during resizing......and the dent worked out when fired. These were rounded dents....no creases, cracks,etc.

It's 100% creased. I'll toss it

Why R17 instead of h4350?

That’s tolerance. Set up your die with any piece of brass so you bump the shoulder .002-3. Once you get the die set up. Run a virgin brass that hasn’t been sized bbyou May have to make a slight adjustment

You want at least .002. Of bump
