The 22 creedmoor thread

[BBob]

It should be fine. Sammi fb is .120 and I’ve ran 90smks with an .080 fb without issue. The BS is just seated slightly below the neck/shoulder junction.

SAAMI FB is .080” in the 22CM. FWIW IMO optimal FB for the 80’s is .120 and for the 88’s is .170. Can or will non optimal still work? Yes. 88’s in the .120 will have the base of the shank right at the neck shoulder junction.

I found out that it was both the Hornady 80-88's. Sierra TMKs in both weights were the easy button. 85.5 Bergers too.

I'm always curious why you don't hear more about the 85.5's. Seems like they don't get much love

Kid shot her first deer with one last head. Just over 100 yards broadside. She hit forward if the shoulder in the base of the neck. It was a giant wound. Deer was dead instantly.
I was worried about the small chance the Berger might not have a good expansion. Went to the TMK.

I’ve had the same concerns. Everything I’ve read has been positive though. Just surprised they aren’t mentioned more

My tikka sbr was approved for 12.5" 22 cal. My plan was 22 ARC. That would require a new custom barrel.

However, I have a 20" PBB 22 creed barrel laying around, and it would be cheaper just to have that one whacked off.

Is a 12.5" 22 creed a crazy idea? With an og-6s, I'd have 1/4" between the can and the fore end of a stockys vg.

Opinions welcomed.

To get quick drop:

You'll be good if you're shooting 77s.

If you want to shoot 88's it'll be too slow.

I can understand why you might want to be faster than quick drop, but...why would anyone want a barrel that's slower than quick drop unless you're shooting subs?

I'm talking about 22 Creed. I don't see any point to put a 22ARC in a bolt gun, but especially a Tikka.

I will die on this hill….

If you want an AR, run the 22 ARC. It’s what it was designed for.

If you got a bolt, run the dang creed!

Should add, I have an ARC bolt face for tikka and I have a tikka in 6 ARC that is a hammer on prairie dogs.

So I'm strictly looking at barrel and powder costs, barrel life, and maybe sound/fireball potential with a short barrel creed. I don't know how much velo I would realistically gain in 12.5" with a creed.

I think it will be a lot of fps.

I look at the ARC velocities on short barrels posted on here and wonder "why?"

The creed case capacity is what gets you "there" in an SBR.

The ARC, GT, Dasher etc. seem to be for guys that want longer barrels than 16-18".

 

[rugerhoyt]

Well I’ve mulled this build over for a long time now smh. Is the saami chamber/fb ok for the 80eldm ? I ask because It appears criterion only offers the saami and a .169. I’d shoot factory loads initially.

Okay did a lot of tinkering last night. Don't have my book with me so hopefully I don't confuse the 73eldm 22CM i loaded with the 80gr eldvt 6PRC with the new "deer" 22 cm load.

New LRP Petersen Brass
88 grain ELD
Federal GM210M primer
18" 1:8 PBB barrel
.081 FB.

CBTO with the 88's was 2.0300", I loaded to 2.0100". Bullet sits in the top 3rd of the shoulder. I loaded a pressure ladder up to 41.0 grains of H4350 and never felt the bullet "crunch" into the powder. As soon as its not 95 degrees and 90% humidity (dang corn sweat) in Nebraska I will get these shot. Biggest concern right now is I'm a little under twisted on the barrel but how do you not play mad scientist when its to hot to be outside. If they don't work I'll look more into the 22 PRC

Thank goodness for blue painters tape to keep everything labeled. I have random loads sitting in boxes all over waiting for the weather to cool.

Okay, I'm sold. Creed it is. Thanks!

What is your definition of top 3rd of shoulder? In a 22CM with .081” FB and a COAL CBTO of 2.010” the bottom of the bullet shank of an 88 (TMK or ELD-M) is way below the neck shoulder junction. Regardless of COAL CBTO number the base of the bullet shank with an 88 and .081” FB is still well below the neck shoulder junction.

 

[Grizzle]

Man I guess I've been lucky but the 88eldms shoot excellently in my 7 twist barrel, sounds like I'm in the minority though. So far about 30% better than the 88 TMK. They are both usable and I will be trying the tmks on game this season but they definitely give up some accuracy to the eldm in my rifle

CBTO was 2.010 not COAL.

But you are correct. I mixed my terminology up. I meant the boattail on the bullet, sits at the top of the body/shoulder junction.

After seeing the results from handloading short barreled 22arcs and 22cm’s I think with top end bolt loads with the fastest powders a 12.5” 22arc will be around 2800fps with the 80eld and the 22CM would be around 2950fps. The 22CM will be much louder suppressed obviously. The 150 additional fps will give you another 100yds of effective range before you drop under 1800fps. Basically to 800yds vs 700 with the arc at my DA. At the cost of more noise, recoil, and less barrel life. For me personally I’d prefer arc for 12.5” but If you want the baddest .22 sbr nothing wrong with running the creed. We’ll see soon I sbr’d one of my tikkas about a month ago just waiting for it to clear.

I thought I wrote and intended to write CBTO but my brain took over and still wrote COAL. I’ll fix it. With .081” FB the bottom of the shank will be ~.050” below the neck shoulder junction.

I mean I guess realistically a .100 -.120fb would be better on the 88’s..

I still don’t know what fb will be best for mainly 75’s-80’s with the possibility of experimenting with 88’s. I was really hoping that the saami fb would work decently for that scenario/plan.

I’m assuming that with the saami fb the 75’s-80’s work well, it’s the 88’s that are marginal? If that’s the case I may just scratch off 88’s.. I’m really looking for the flattest shooter on deer/fox/coyotes/chucks out to 5-600yds. I may play with some steel at 1k but that’s not often.

Mine took about 3 months in a trust.

75 & 80eldms the bearing surface will be above the neck shoulder junction in the .081 fb.

The trust usually take a little longer. I did an individual and they told me it has been taking about a month. Which ever you go with Arc or creed let us know how it works out.

 

[BBob]

I’ve posted multiple times in threads that IMO the optimal FB’s for 88’s is .170”. That puts the bottom of the shanks above the neck shoulder junction. The OAL fit mags and mag boxes fine with those numbers. Now will other FB’s work fine? Yes, but if you want optimal and have the choice there’s your numbers.

P.S. FWIW the optimal FB for the 80’s is probably .120”.

P.S.S. I have .120” & .170” reamers and have chambered barrels with both.
