22 creedmoor

[psinclair]

I've been shooting 22 CM's for the past seven years. all six of them have never had a bullet blow up in the air....

No tight bores, all of them have been .219's, and I don't let the carbon build up. all of them are either 6.5's, or 1-7's.

I've driven 88's and 90's past 3250fps, 75's past 3600fps with zero issues.

 

[6brshooter]

Mind sharing which 90s? Thanks

I can blow up Bergers in a 1:7 at 3250

 

[zandnubbz]

How fast are those loads?

I have a 6.5 Twist Bartlein 5R at 24"... I would run 88s at just over 3250 and they would no show to the target more than 50% of the time. The 95 SMK... they don't hold together at about anything over 3060... I went down to 2950, but switched powder recently and the new node is a touch faster and I knowingly will likely lose a few. (not used for hunting or comps, so living with it). I was going to shoot solids, but at the end of the day just decided shoot it out and likely be done with the 22CM and move over at a 22GT or 22 Dasher.

I had a second barrel spun up for an Impact and went a little shorter freebore to run 85s to 95s and also went with a 7.5 twist Benchmark at 26". Never used it much and gave it to a friend and he absolutely loves it. He has had phenomenal luck with this combo... My experience says to stay with a 7.5 twist at roughly 0.100 freebore, but again, that is just my experience. (keep in mind, my opinion is free, and you tend to get what you pay for!)

I've been contemplating moving to 22 dasher after this barrel and I think it's almost done.

I think the 22 creed is great, don't get me wrong, but for what I use it for now, a 22 Dasher or 22 GT I think is the ticket! I originally built a 22CM for coyotes... but then went to a 6 PRC and have not looked back.

The 22 Creed is my favorite for shooting yotes but a Dasher would work just as well IMO. 6 PRC would be sweet also.

Why not just use a slower twist to keep the RPMs down? Sure, the BC may not be optimized but whatever. Mine is a 7.7" and I use 4831SC and keep it under 3150. That's 295K rpms. I'm at 6000ft ASL and the BC is optimized at this elevation. The 22 Creed can work, but some of these long, pointy high BC bullets are flawed logic wise.

I've got another 7 twist barrel sitting here. I guess I could sell it. Probably the smart thing would be to slow the twist down and shoot a bit lighter bullets.

I agree, I think the 7.5 or even a 7.7 twist is perfect.

 

[6brshooter]

Or a gain twist that starts at 8ish and goes to 7.5 or 7.25

 

[WasNH4X]

I wonder if a 219 bore Shilen ratchet rifled 1:7.7 or 7.5 would be optimum

Don't know about the 219 bore or the twist ,but for a button barrel ,all four of my ratchet rifled barrels are " shooters".

Yeah, that's where I'm at. I did just talk to Sierra tech, he was pretty familiar with that 95smk and it was designed for service rifle and needed 6.5 tw to stabilize it but it wouldn't take the rpm that the bigger 22s would launch at. I did tell him that some guys were getting them to work and his reply was wait until their barrel has 4-600rds on it and see how they like it. I asked about the 90gr smk and he said it was the same as 95, just not designed for the bigger 22s speed. Super nice guy and seemed fairly knowledgeable but not sure what the point Sierra is trying to do. Make the big heavy for caliber bullets for cartridges with balls, not 223 or 224valk. He recommended the 80smk for its toughness, but its pretty lame bc wise. I will soldier on with the 85.5 as they haven't landed sideways and have shot the better groups so far in testing.

I bought a lot of the 95smks the other day. Im planning on running a 16” 6.8 twist with the next barrel and pushing them around 2800fps to keep the rpm’s around 296k. It will be a hunting gun anyway and should still have less wind drift at distance than the 80elds I’m running at 3070fps out of an 18” Bbl now.

I’m running 95 smk’s in my 22 creed around 2880 in a 6.5 twist 18” barrel with good results

 

[DLS]

I have been playing with the new 62gr ELD-VT’s and they sure add another gear to the 22 CM.
In my short barrel 20 inch they easily cruise at 3550 and in my 26 inch I stopped at 3720 as I am getting up there in RPM’s in a 1/8.
Only shot a couple coyotes so far but they seem to be accurate and deadly.
I agree with the above a 1/7.75 is probably the ideal twist and I just go 1/8 for my purposes But have always thought anything faster twist was too much of a good thing.

 

[Kjb1796]

Glad to hear the 62 ELD VT are working well. I plan to load some in both 22CM and 22-250. Both 1:8 twist.

 

[6brshooter]

Found a couple powder charges with the 85.5gr that seem to work, 3205(bottom 5) and 3235(top 5). Felt a few in bottom group break high and right, scope is farther back than optimal for prone shooting and felt a bit scrunched up.

 

[6brshooter]

On a side note, has anyone saw or dealt with a first shot faster than rest in string? For some reason, irregardless of powder charge, the first rd in every 85.5gr load is 35-45fps faster. Confirmed with magnetospeed and Garmin. Switch to different bullet and it's normal. Rd Robin between 85.5 and 95smk strings and first rd of 85.5 was fast, normal speed on 95smk. Any ideas? I don't think it can be barrel or loading technique as it's consistently first rd and always/only with 85.5s.

I've never noticed it, I'm using H4350. The ES is always low when I check velocities.

It's not powder related as I was using same powder with 95smk. I've got some 90gr vld ordered to try. If the 85.5 shoot the best, I'll take them to 800 and see how they watermark.

 

[Iron Worker]

What's a good starting load to obtain the highest velocity shooting the new Hornady 62gr ELD-VT bullets 26" bbl 8" twist?

 

[Iron Worker]

Starting load. I have numerous Fast, medium, and slow-burning rate powders. Re#17 was suggested. In my standard 22/250, W-W 760 is king. In my 220 Swift 4064 and AA 2700, produces high velocities.

 

[DLS]

Out of those W-W 760 would be a good choice I think. I have ran 4000MR out of a 26 inch barrel at 3730 fps. My load was 44.5gr but of course hasn’t been pressure tested so use at your own risk.
Currently I am using Reloder 15.5 and my max is 40.5
Just so no confusion this was with 62 gr VT

You mind sharing which powders you've tried in your 20" w/ 62 VT's?

4000MR and Reloder 15.5 both will get 3500+ from a 1/8 20 inch barrel.
Don‘ t know if I would try the 62 VT if I were running a 1/7 twist due to RPM ‘s but I am sure someone is or will so that will shake out as more folks get their hands on them.

 

[DLS]

I might add Alliants 4000MR is a great all around powder that’s overlooked by most. It’s one of the top velocity getters in the 6.5 Creedmoor with heavies and is usable up thru all the Medium & Magnum cartridges. Also unlike all the overseas made Alliant powders the price hasn’t shot to the moon.

Mine is a 20" 1:8. Still working on barrel break-in but Varget and 69 TMK's as well as 75 ELD-M's with H4350 both show promise. Would like to try the 62's when I can find some.

I might have missed this - which powder are you using?

 

[6brshooter]

H4831sc, Peterson srp, and cci450

 

[Iron Worker]

Has anyone used Short Action Customs dies for their 22 Creedmoor or any caliber? They're expensive. Are they worth it?

 

[mjspeers]

I use the SAC seater and sizing die. I think they’re fantastic. The seater is great for everything in the bolt head family. If you do anything else in the creed family with the sizing die, there’s utility there. I started with a set of Whidden, the seater crushed the case.

 

[BigOldPhatboy]

Totally worth it for me. I load 22, 6, and 6.5 Creed. the sizing die allows me to taylor the amount of sizing to whatever brand of brass that I am using.
Whether it be Lapua, Alpha, or Hornady.

 

[DCC83501]

I load for 6.5,6, and 22 Creedmoor myself. Most bolt, but couple gassers as well. SAC bushings in use but may have to look at SAC full length sizing die.

 

[max1840]

I load for 6.5,6, and 22 Creedmoor myself. Most bolt, but couple gassers as well. SAC bushings in use but may have to look at SAC full length sizing die.

I load for the same calibers also and use the SAC sizing die for them. You also get the benifits of the neck/shoulder bushing.

edit: plus the expander operation all in one step

 

[6brshooter]

After a seating depth test, I settled on 43.1gr h4831sc and .010 off with 90gr vld. Shot them at 750 today to see how they watermarked, decent breeze from 4 o'clock. Right at 120ish rds on barrel and looks likenits sped up from the 3220fps this load runs.

 

[Iron Worker]

I've found the loads I'll take to MT Prairie dog fields. 132 rounds down my new rifle. 26" Rem Varmint contour Muller works 8"twist bbl Bat Igniter action McMillian Game Warden 2.0 stock Trigger Tech Special trigger.
Alpha brass 41.0 gr of H4350 75gr ELD average velocity 3537 6.6 SD out of 10 rounds tight groups on a cold, windy day.
Alpha Brass 42.5grs H4350 behind Hornady's new 62gr ELD-VT bullet out of 5 shots average velocity was 3,844 MOA SD of 23.9 43grs out of 5 shots was 3,873 SD of 11.8same MOA accuracy Then I tried some 60gr Nosler BT with 43 grs of H4350 Peterson brass average velocity was 3,880 with SD of 16.3 and then 3 shots of 43grs of H4350 behind a 55grs Nosler varmingeddon for 4,040 FPS with under 1/2 MOA all at 100yds. My rifle doesn't like H1000. I wonder which of today's loads will be the hardest on the barrel. Also, there are zero pressure signs and no hard extractions.

 

[wildturkey2]

Tried some new powders, I was very cautious on this lot and will be bumping the charge up after this batch. This was a super accurate load but rather slow for this cartridge.

80gr Amax
imr 4451
38.4 gr
3105 fps
*mild recoiling, could see shots appear on paper with can on*
24" barrel
da: 1300, 75 degrees

Pederson data shows 43grains of H 4350 running a 80 grain bullets to be way over pressure.am I missing something? I just had a 22 CM built so just wondering just have to work up I suppose. where did you guys start say 41 grains .

 

[6brshooter]

My barrel sped up about 80fps and the solid load was now making faint ejector marks on a few pieces of brass. Slowed back to 3234fps Ave with a 4.8sd over 10rds. Here's the 5rds on paper, the other 5 were on steel, downrange.

Peterson srp, cci450, 42.4fr h4831sc, 90gr vld .010off in a 24" 7tw criterion.

 

[DLS]

In my rifle 42.0 gr of H4350 was above 72,000PSI with 75gr in Lapua necked down brass FWIW. There is a reason Hodgdon doesn’t show any data with H4350 with any bullet weights in 22Creedmoor…..just say’n

 

[Kjb1796]

Just wondering how many rpms are these bullets going to take before they start not getting to the target?

I thought about 3400 fps in an 8 twist bbl was about the limit?

 

[Wes owens]

Are you using Large Rifle Primer brass for your loads on the 75 gr ELM?
I’m still shooting some Copper Creek 75ELMs and I’m in process of start loading for it. Got plenty of H4350

Not sure they want you to do a load pack and buy at least 100 rounds and they’ll give you the data

I pulled one apart 80 gr ELD,it looked like H4350. Out of my 26"bbl rifle I was getting 3350 with close SD

It was 41.3 grs, now am I certain it was H4350? It sure looked like it, or was it Re#16

Don't have any hi res pics of that powder, do you? All the re16 I have is dark charcoal to black and is irregular cut/shaped pieces. H4350 is kind of a greenish-dark grey color and is pretty uniformly cylinder shape and all kernals are very close to same length.
