22 creedmoor

[browning442]

I'm interested to hear on RL26 and 4831sc also.

 

[NICETRY]

NICETRY, Or anyone using the Alpha brass. What size bushing are you using?
I'm waiting for the barrel and picking up things for when I get it from PVA
NICETRY, earlier you posted you liked the RL26, except it carboned up badly
how did the 4831sc work out?

Off the top of my head not sure but I can check this weekend when I get home.
H4831SC is working great. With 95 SMKs running 42.0 grains and getting 3150fps. With 88 ELDMs and 43.5 grains I’m getting 3370fps average.

 

[browning442]

Might have to switch to 4831.... cannot find RL 26 anywhere on planet earth

.253 bushing works great for alpha 22 brass gets me .0015 tension

 

[xpshooter]

my go to powder is RL 26 with the Sierra 90 gr Matchkings and couldn't be happier with the performance. Just hoping it comes available again before I need some more

 

[longrange2]

I've worked up some loads with H4831SC for 88 grain ELDs and got a couple nodes that were acceptable but not quite as tight grouping as I was hoping for. I'm going to give some 80 grain ELDs a try with H4350 and H4831SC. I haven't been able to find any RL26 locally to try with the 88's

 

[Elnicko]

Anybody tried superformance with 80s or 82s? I have some 83 grain hammers I want to try. Hornady has 6.5 and 6 creed loads up so I figured it might be worth a shot since I have 8lbs laying around

 

[platapus]

Is anyone running either the 75gr or 80gr JLK’s?

I’m building a 22cm and want to know how these are on fur as this will be a dedicated coyote rifle.

Thanks in advance

 

[joeh]

You guys have me itching to build one of these.
Can’t decide on a twist or which bullet.. I will use the 80eldm or 88eldm. Suggestions welcome...

I will have to look at case dimensions but couldn’t you use a 22br for a seater die?

 

[Ranger188]

I don't have my barrel yet, but most of the other items. Loaded a dummy round using my 6 creed
microseater and did fine. Was using a 88 eldm
If you run the #'s you need a 7 tw to run the 88's 90's and 95 gr. to get the full B.C. value
i bought 75 eldm, 88 eldm and the 90 smk
I'm going to start with the 75's if you run them fast, they have less drop than the others
and the drift is not that much different, even out to 1000 yds.

 

[joeh]

I think I’d rather gear toward the 75-80gr eldm running 3400
What’s the preferred twist for those? Looks like I can get either 1:7.7 or 1:8 twists

 

[Ranger188]

Here are two links, you can use to figure out the percentage of B.C. for a given
bullet and twist, plus environmental factors.

Bullet length, http://www.jbmballistics.com/ballistics/lengths/lengths.shtml

Twist rate calculator, http://bergerbullets.com/twist-rate-calculator/

 

[joeh]

Thanks, I’ve played with both of those. Berger calculates out to need 1:7.5” for the 80eldm.
I see 1:8 guys shooting 80eldm fine. Thought about splitting the difference and going with the 1:7.7”
But then I could get the 1:7 and cover all bases.

I don't know the specs between the 80 gr ELD and the 80 gr. Nosler CC but, my 1:8 handles the Nosler perfectly at 3500 fps.

 

[joeh]

80gr-
Nosler is 1.065”
Hornady is 1.162”
Berger calculator shows 1:8 being fine for the Nosler.

 

[Ledzep]

Everybody has their own warm and fuzzy feeling... That berger calculator is very conservative IMO. Anything with a factor of 1.2 or better will run reliably in my experience. Running the 90's at 3000fps in an 8 twist I have not noticed any BC loss out to 1300-1400yd. YMMV

 

[Ranger188]

I do agree, seems a little conservative to me also.
Just posted to give some help to those that are on the fence
in deciding on barrel twist. When in doubt, go to a faster twist.

Here's another twist chart. A little less conservative.
https://www.jbmballistics.com/cgi-bin/jbmstab-5.1.cgi

 

[Ledzep]

Yeah, usually better to err on the faster side than the slower, but with these small bore calibers we start getting into the realm of blowing things up. A 6 twist @ 3400fps is spinning 408,000 rpm. Usually you start seeing blow out problems around 350,000 rpm. A 7 twist is right on that line, 349,000 rpm.

Now every bullet is different, and some are more susceptible to flying apart, but it's also worth noting that as bore condition deteriorates and you start getting rough spots and fire cracking you get other issues (friction heat and jacket deformation) that tend to let bullets fly apart even at much slower RPM. It may be that the smaller you go, the less internal mass (Pb) there is trying to "get out" so you can spin smaller bullets faster without blowouts.

Just food for thought. There is an upper bound as well as a lower bound. Neither are really set in stone.

 

[Codiekfx400]

I have a Mullerworks 7.5 twist I have been thinking about building a 22 Creedmoor or a 22-250 ai. Are die sets availiable yet for the 22 Creedmoor for a reasonable price. Example Forster or lee or Hornady?

 

[Ranger188]

Funny you asked, I just called Forster today ( I don't live that far away and bug them )
They said they plan on it "some" time this year. Hornady makes some, but I personally
wouldn't buy theirs. Whidden makes the only other ones I know, and a few people here
have said their quality has gone down some lately. I'm going to buy a Whidden custom FL
sizer and can use my Forster 6 creed micro seater.

I use a Redding 6.5 Creedmoor FL Bushing die with the appropriate bushing for sizing and a Wilson 6.5 Creedmoor Arbor die with a .22 seating stem. Works out very good. Got everything from Sinclair's.

 

[joeh]

Wow, I haven’t even looked at the bullet rpm with 1:7twists. Rpm is so far up there it’s scary. 349,000rpm is above my redline.
For me only wanting to run the 75 or 80eldm to about 3400-3500 I think I’ll stick to a 7.7 or 8 twist.

I use a Forster 6 Creed sweater and Whidden 22 Creed sizing die. The 6 Creed seating stem fits the heavy 22 cal bullets perfectly. I caution using a 22 seating stem in a 6 Creed die because when I tried it the 22 stem had some play side to side and could have some runout issues.

 

[joeh]

Anyone using H1000 in these? Is there enough room?
Maybe we could get extended barrel life using it?
I only ask because I have a bunch of h1000 not in use. On the other hand I have plenty of h4350 and 4451 also...

I'm using RL26 with 90 grain Sierra's so I would think H1000 should be worth trying, close to the same burn rate and since you have a bunch of it, why not?

 

[Buzzbee]

Accurate Arms is where I bought my dies, They are cistom's from Redding, $125 If I remember correctly. . They may be out as this caliber is skyrocketing. I'm backordered on Hornady brass. Brass and RL-26 seem to be the hold up.

My rifle wont be done till May or June 7 twist Proof Carbon.

 

[Teepee]

I've had one built here in Aus and would have to say it's been the easiest wildcat to work with that I've ever had. I've used both Hornady and Lapua Brass and have used a whidden die to resize the necks from 6.5CM cases. One pass and it's done. Load with our 2209 with either the 75gr or 80 gr hornady eldm and Away I go. No neck turning required or any other major case prep required as per other wildcats I have in the collection. It's running a Kreiger 1/8 twist brl and I'm having no issues with the 80gr projectiles. I've tried Berger 80.5 as well. They all have grouped well!
In respect to the whidden dies, the resizing die is very good, the seating die not so much but I've managed to get hold of a set of redding 6.5 CM dies and use the seating die without any issues. Havnt bothered fitting it with a 22cal seater, it just seems to work as it is and is all I need at the moment. Cheers from Aus, Teepee!

 

[dirtbiker250]

my 22 has been a bit frustrating. Was a PAIN to find a load for it. Finally found one that’s decent It’s been about .5” at 100 most the time. Sometimes a tad bigger. Don’t know why this one is so finicky but oh well. It’s a 21” bartlein #3 7.7 twist 42 grains of 4451 in alpha LRP brass with a 75eldm jammed .003. 3330fps. Pretty happy with that speed ! 4350 and 4831sc both sucked in this barrel It’s just finicky. Hopefully when I shoot it out the next one is easier to load for. Took me 230 rounds to get this load LOL.

 

[22creed]

Rechambering to 22 creed from 22-250ai and curious how close people may have found the data?
Some posted here looks well above the ackley's ability for having very close case capacity.

I’m currently working up a load for the 62gr Barnes TSX and started out with 22-250 AI data to get me going and have found it to be rather conservative. Where max charges with Varget are approx 38grs with the AI, I was at 41gr today with only minor pressure signs with my 22cm. I was seeing 3,550 with a 22” bbl today. Naturally, YMMV and you should always work your loads up.

 

[Buzzbee]

Lots of new testing going on. Do we need a sticky for ACTUAL, PROVEN load data/recipes?? If not "sticky" worthy, how about evreyone who has SOLID data post it here.
With everyone trying different unproven powders re; 4831, H-1000, IMR's new powder burning close to RL-26?

My new rifle should be ready may-June, I want to hit the ground running'

Thanks

I agree. I gave up on Varget for the 62grs TSX and am going to run a similar OCW test with reloader 15. Groups with Varget weren’t bad, most just under MOA but I’m expecting much better from this rifle and wasn’t willing to settle. I also tried CFE 223 which was giving fantastic velocities and groups but I was getting more than occasional delayed ignition with the small primer brass I’m using. I’m also testing the 78gr Barnes TSX with both 4831 SC and Norma MRP and will report when able.

 

[EXSOCAL]

Just shot my 22 Creed for the first time yesterday. I had no clue where to start so I loaded up from 38.5 gr - 42 gr in .5 gr increments of H4350 behind a 95 SMK seated .010 off. I fucked up and left my chrono at home.... the barrel is a 24” Krieger 4 groove 6.7 twist. I had light ejector swipes on the brass on everything north of 40 grains and had a moderately sticky bolt lift from 41 gr and up. Accuracy was below .5” for everything. The average point of impact between all groups fired was nearly identical with the best group (.212”) being 39 grains of H4350. Ill be using 41 gr as my pressure ceiling and doing an OCW test next week. So far I’m very impressed. Brass was Alpha SRP brass.

 

[Buzzbee]

Thanks SOCAL, great info, sounds like you have a GREAT start !!

What about RL-22 ?? anybody try it?

 

[Ranger188]

What bushing size are you using for the Alpha brass?
Let us know what fps your getting if you

 

[Elnicko]

Anyone know if I can put a 22 seating stem in a 6.5 Creed Redding seater? Using a whidden seater currently with less than desirable results...

 

[Ankeny]

For those who are not into precision reloading, Hornady 22 CRDM dies and brass have been shipping for the last several weeks. While I prefer Redding dies, I did get a set of Hornady dies and some brass. No problem whipping up sub-moa ammo with H4350 and 77 TMKs. Good enough for my purposes.

 

[oldnmkid]

That's what I did. Works fine.

 

[Huckleberry75]

I used a Redding 6.5 creedmoor bushing die and put a .251 bushing in it. Necked down alpha (the alpha was neck turned to .014) and lapua both, and both necked down just fine. However, test seated a bullet in both, and on the lapua i can see where the base of the bullet i sits in the neck, a "bulge' of sorts. I'm thinking i may need to step up to a .252 bushing with the lapua and see if that works. hoping to not have to neck turn.

Also in seating i used the standard 6mm creed seating die and it actually worked good, i was seating berger 70 grainers

You will want a .252 bushing for Lapua brass. The .251 will serve you well for Hornady brass.

 

[platapus]

I'm looking to do a side by side with H4350 and Hodgdon Hybrid 100v with 80gr bullets. Does anyone have any experience with the Hybrid 100v load range for the 80s? Will be using Lapua srp.

Thanks

[triumph001]

Hey SOCAL, Do you have any chronograph results you wouldn’t mind posting on the 95’s with 4831sc. You are the only one showing any loads starting below 40 grains. I am ready to start loading for my gas gun and wanted to see what you were getting for velocity at your lower power loads.

If anyone has any experience with the 22 creedmoor, specifically 90 & 95 mk’s, on a large frame gas gun I would appreciate some starting load suggestions. Please keep in mind it is gas gun and my nuts are pretty small so mild is where I need to start. Also Rl26 is not part of the equation for me at this time, there is none within 100 miles of me, I’ve checked.

 

[BeAccurate]

0.257 NK OD is pretty standard. I run 95 smk at 2.775 so I had to use a uni-troater.

Barrel life is decent, around 1400 round in PRS condition. 1800 to 2000 if you take care of it.



Could be interesting but Alpha is already making them and their are alot more consistent.

Could you specify the difference between PRS and "taking care of.it"?

Is this load pressures or speed of fire, too?

I'd ideally like a 22 BR bc of the nice compromise between barrel life and velocity but the 22 Creedmoor is appealing bc it seems like you can run it on the milder end, get velocities equal-or-bettee than the 22 BR while doing so, and not make a huge sacrifice in barrel life.

Is this an incorrect assessment?

 

[Huckleberry75]

PRS will have the barrel running pretty warm with strings of fire up to 10 or so rounds for a stage. This tends to accelerate the fire cracking and throat erosion much quicker than a hunting rig which might get the longest shot strings just doing load development and then zeroing/chrony work. After that you are usually only firing a few rounds at a time depending upon what critters you are chasing, which this type of use will not burn up the barrel nearly as quickly.

 

[XTREM HTR16]

Well crap, just went through this thread thinking I'd like to take a longer range lighter recoil rifle on a prairie dog shoot this summer. Looks to be perfect for those longer shots. So I ordered some Alpha brass. now i need a rifle, a scope, some dies and some bullets... grin

It never ends!!

 

[Huckleberry75]

And then you will want to build a fast twist rifle and a slow twist rifle....ask me how I know

 

[XTREM HTR16]

Eh2, check
Bartlein 3b, chrck
APA DBM, check
GAP build sheet, check

Gotta package it up and send the parts in. Then wait....

 

[Dschapp44]

Just got back from trying out a few combos after getting the initial break in done. Shooting a 7 twist Bartlien spun with a .080 freebore reamer from PTG. There is definitely room to extend that out to a .180 freebore and still have a COAL in the 2.770 area with the 95 smk. With the longer freebore it would put the start of the BT just past the end of the neck into the case.

80.5 berger
New Lapua 6mm SRP brass
Coal 2.590
Fed 205M
H4350 40.5 grains
3440 FPS

Hit a 2 inch target at 300 yards with three out of three shoots.

95 SMK
New Lapua 6mm SRP brass
Coal 2.670
Fed 205M
H4831sc 39 grains
2985 FPS

95 SMK
New Lapua 6mm SRP brass
Coal 2.670
Fed 205M
H1000 41 grains
2880 FPS

The brass holds 44.5 grains on H1000 to fill up to the neck so there should be enough room to hopefully hit 3150 after the barrel speeds up and i do a ladder test to see what i can push. If i have to extend the freebore to hit this its definitely worth it
