22 Creedmoor
-
Been having fun with the 22CM lately. Got a thick batch of 6CM brass, so had to turn all that before necking down. Start off with a .260 bushing, then a .250 bushing. I could stand to go down to a .249 or even a .248, but there's plenty of neck length so it still grabs the bullet alright.
Some data:
80gr Berger @ 2.080 to ogive
Varget
40gr - 3475fps
42gr - 3627fps - blown primerH4350
40gr - 3222fps
42.5gr - 3372fps
44.5 - 3556fps - pressureH4831SC
44gr - 3315fps
46gr - 3434fps
47gr - 3505fpsI worked with H1000 as well, but didn't record any velocities as the case fill was getting up there. 47gr of 4831 runs about 1/4 way up the neck... 46gr of H1000 about fills the neck. Velocity was round equal, and I didn't see any real accuracy benefit. I hate running compressed loads, so I opted to stay away from it. Case fill with H4350 was real nice, so I opted to work with it the most.
43gr of H4350 ended up being my chosen load. Just on the plus side of 3400fps and shoots sub-1/4moa at 100yds and around 1/3moa at 300yds.
I can't wait to anchor some coyotes with this thing soon.

How flat does it shoot?
-
Have you tried the new Reloaders 23 and 26?
How about Alliant Power Pro 4000 or 2000?

2.3 mils to 600yds

How about Alliant Power Pro 4000 or 2000?No I haven't. RE powders have no place in my reloading room, as any load I'd work at 90f would be worthless at 10-30f when I'm hunting coyotes. I have never worked with alliant PP4000 or 2000 ever. I can usually get everything I want using powders that start with "H," and I really have become fond of their "extreme" line of powders over the years. I wasted countless hours chasing my own tail with other powders. Hodgdon tends to have much better lot-to-lot consistency and the Extreme line is quite temp stable.
I have many 8lb jugs of Varget, H4350, H4831SC, H1000, Retumbo, and H50BMG. The only time I had to stray was when I recently searched for a subsonic 300BLK load.
-
The new reloader powders are supposed to be more temperature stable.
-
I'll let someone else experiment. From what I've read, they are "more" stable... but still not as stable as hodgdon.

Isn't IMR owned by Hodgdon? I know that H,I and W powders all have the same address on the label.
I'm not sure it counts as cheating....
-
Yes, IMR is owned by hodgdon... however that does not equate to the products being equal, because they are definitely not.
-
Untouched 6CM on the left, turned and necked down 22CM on the right. :)
-
Turned necks are always a beauty, and that one is no exception.
-
Oh, I was gonna ask, how do the speeds compare to the 22-243 AI? I would expect a bit slower.
-
Yeah, the .22-243AI has no problem stacking another 100fps or more on top of what this does without breaking a sweat.
However, the 22-243AI doesn't fit very nice in the DT magazines. The 22CM does! :)
22CM is basically a ballistic twin of the 22-243win. The shoulder angle and overall cartridge dimensions of the creedmoor are a bit more appealing to me. Now all we need is for Lapua to get off their ass and give us brass!
-
Rumor is they're working on it.
But on the internet you can find rumor for anything.
-
Yeah, I had heard they were in process on it.
-
Got the load dialed in today. Let me just say... coyotes are in deep shit this year. It's going to go down about like this:
Here's 3-shot groups while dialing in the zero and finalizing the node.
Here's 2 individual confirmation shots.
5-shot group. (yeah, one had to get away from me. kinda breezy.)
80gr berger going 3525fps is going to punch their lights out. It's time. Time for blood.
-
Whew! Had to update the velocity. This barrel has really come to life since I started shooting it. During my initial testing, this charge weight was only getting 3400'ish FPS. Now, I'm at 3525.
Oh boy! I like it.

Why you using the full sized mag?
-
@rhyno said:

Uhhh... I'm not.
Easiest way to tell is to look at the feed lips. The short magazine has feed lips that extend forward, and have a slot undercut. The long mag has the feed lips without an under-cut and they don't extend forward like that.
-
Huh, I thought the short magazine was upside down L shaped.
Learned something though.
-
Only the 10rnd'ers.
-
I see, thanks.
-
Greg, any idea on barrel life on the 22 creedmoor? When I finally get saved up for my DTA, I was looking at that to cover my 22-250.
-
I'd expect it to be a lot like the 22-243. 1000rnds or so. You don't get a hot 22cal if you are concerned about barrels.
-
53rnds since the last cleaning, and the 22CM is still killing black dots with ease.
-
Had 53rnds through the 22CM since the last cleaning, so it was time. I have shot fast .22 cals for a lot of years, and figured I'd have my work cut out for me. Dreaded it... really. Usually takes a LOT of scrubbing.
If this is how .22CM's behave... I'll be switching ALL my fast .22cal's over to 22CM when their barrels go.
This is literally ALL of the patches I used, in order. It was the barrels second cleaning since new... and after 53 rounds fired!
After cleaning a new barrel, I always take extra special care to give honest shots on the first few rounds, and I do it on paper at 100yds. How a barrel reacts after cleaning tells a LOT about its character.
Clean bore, shot #1
Shot #2
Shot #3
Shot #4 @ 300yds
I've had some hammers in my day, but this thing is really laying it down.
-
It takes a good shooter to show how good the gun is.
Don't sell yourself short.Those dot drills are tough.
-
This is a benchmark barrel, correct?
-
@ragnarnar Always!
-
Went out today and confirmed firing solution prediction at 525yds, 836yds, and 975yds. 15mph wind didn't stop me from thumping everything.
-
Around 5 mils to 1k? 500+ foot pounds.
What is max sporting range for fur?
We know you can hit it.
Do you prefer to call them in as close as possible?
I cannot recall any video where you intentionally let one go that was within range.
-
I want to see one like this. Unnecessary, yes. Unethical, no; its a coyote.
Plus this would be childs play for that .375 CT you have.

I cannot recall any video where you intentionally let one go that was within range.Yup, your numbers are real close.
I'd have no problem taking a shot at 1200yds or a bit past if I had the opportunity. However, yes I do take great pride in being able to get them to come right up to slingshot distance. Travis and I tag teamed that one dog on video at 600yds, but it could have been him that hit it for all I know. Eventually a situation will present itself where the dog just doesn't want to come in, and I'll have an excuse to dump one out at distance. For the time being, it seems that the Primal Rights predator calls drag them right in. ;)
I had a 3-shot group the size of a bottom of a pop can at 836yds today... in a 15mph cross wind. So if I get the opportunity, chances are good we'll have some good footage of it. :)
-
Parent casing for this would be a 308 technically correct?
-
Nope. The 30TC was the basis for the 6.5CM. The 30TC was derived from the 300 Savage.
308 bolt face for all the creedmoor cartridges though, if that's what you're after.
-
@orkan That's more what I was after. Just worded it wrong I guess. Thanks you sir :+1:
-
Going out to shoot some dogs this weekend, so I wanted to check my cold bore and test a new suppressor. Going to a 22cal ultra-7 instead of the 30cal ultra 5. This thing is a TON quieter than the ultra-5.
-
Loading up my second firing on this brass today. I always load about 10 rnds for confirmation before I do a bunch. Here are 2 individual 3-shot groups at 100yds. The bottom group is seated to 2.060" to ogive, the top is to 2.080" to ogive. Now that I have a firing on this brass... it sure is hammering. My seating depth is still on the money too.
-
@orkan That thing is nuts.
-
@tscustoms Let me know when that new reamer gets in boss. We'll be doing lots more 22 creeds. At least 3 more! ;)
I'd have burned this one out by now if I had another one... but I don't want to wear it out playing around since I've got lots of yotes to smack with it yet! Just a damn laser beam. I literally can't shoot better than it. ... which makes me want to shoot it more!!!!!!!!
-
That is simply astounding really.
-

Fuck. The list grows longer.
I also need the ability to walk out the door and shoot. It a huge production to do any any load development. Load up, drive to the range, shoot, drive home and attempt to interpret my notes and hope I got the right load.
Soon....

I could not live any other way than that. Literally could not.

-
I have just over 100 yards in my back yard for subsonic suppressed shooting. Once in a while I'll tear loose with a few unsuppressed, but even though I am in the county and it is legal I don't want ohe neighbors to get upset at me. I am 2.5 miles from my 600 yard range. I would not want to live where I couldn't shoot at all.
-
My home in Az. was on 74 acres and 2.5 miles from our closest neighbor.
We could and did call coyotes from the porch.
Elk and deer traveled thru our place; the flats held pronghorn.
My sons would hunt rabbit and quail up and down our hill.
I don't think a day went by that we didn't shoot either game or targets.
I truly miss the freedom.

I truly miss the freedom.... but yet you are not there. You're somewhere that you can barely get away with shooting a pellet gun. :(

Must be some type of Karmic sentence. :frowning:

What are you guys using for dies? Taking a 6mm creedmoor bushing die, and just running a 250 bushing? Are you also then using a 6mm creedmoor seating die? Trying to decide on a 22 creedmoor or 22-250ai for my re-barrel, and the die portion is a factor (in addition to the brass).
Thanks for the help, found the initial stuff posted by Orkan over on snipershide.
-
@akscott I'm doing all my loading with a 6mm Creedmoor FL bushing die set. Two steps to neck them down, final bushing depends on neck wall thickness and desired neck tension. Seating is done with the 6mm seating stem as well with no ill-effect.
I know orkan has a custom FL die set on order.
