Same barrel life as my 6 creed. Pulled the first barrel at 1257 and the second a 1520 ish.
Only Runned the 95 smk with H4831SC at 2980 fps. That was my sweet spot.

I already run extra long freebore. Don’t remember the extract lenght but I know it’s 0.160" over max saami.
Never saved any of my 22 creed barrels but maybe you’ll be lucky. With that said don’t expect 2K +
My 22 Creed is just for prs. It has just under 400 rounds on it. I’d have to look, but I’m pretty sure thats what it is. It has 6 thou growth. Shooting the 95 SMK at 3130. In a velocity test I had the 95s over 3200. It was easy to hit them numbers. I don’t see a reason to go over the 3150ish. It shoots great, the 95s have a great BC and I think its a mild load. I’ll have to bore scope it when I get home. I’m sure the case mouth area and first couple inches of rifling don’t look the greatest.
I started playing with my new Craddock 22” 1/8 twist AR10 yesterday. I pushed the 75gr ELDms pretty hard with H4350. I’m using virgin Peterson brass because they had a bulk sale last spring. I guess I’m a little disappointed in the velocity readings and pressure signs.
From the start of this build I knew I wanted to push it hard and not really care about brass life because this will be a dedicated thermal coyote rig with little concern for reloading the brass multiple times. That being said, I got pretty pronounced ejector marks even down to 42.0gr and around 3350fps. ES and SD wasn’t that great.
I ran it all the way up to 43.6gr and got 3,500fps average and good ES/SD numbers. Accuracy was sub MOA with all loads so I’m not worrying about that. I just don’t know how hard I want to beat everything up. I tuned the gas block down right to reliable last round lock back. I’m running the heavy JP SCS. I started with the light spring and went back to the heavy yellow one.
According to Peterson’s load data, I’m way overpressure. I read through all of these pages and I don’t feel like I’m way out of line. Next weekend I’ll try some loads in the 41gr range and see what it looks like. I’m just surprised I’m having issues getting 3,400fps out of a 22” Creedmoor when I’m getting 3,000fps with my 20” 224 Valkyrie with CFE223 and 75gr ELDms.

Did you load those 95 SMK’s at 2.775 and leave it for the life of the barrel? I’m worried if I have it throated for that length that I’ll run out of neck to seat the bullet if I have to chase the lands as the throat erodes.
Both barrels shot well with that load. I’m not sure why the drastic difference but one barrel went to 1400 rounds and still shot. The other started ripping apart 95 smk jackets even below 3000 FPS at 700 rounds.
I had a 6.5 twist and a 7. 7 was definitely better for bullet rpm and saw no BC loss. Would even go a little slower to maybe a 7.5 twist if I spun another one up

How’d the 95 gr SMK perform long term?
[/QUOTE]
The 95’s went in the trash. They couldn’t be pushed past 3090 reliably. Too long bearing wall and finicky like all the new Sierra high bc design.
switched to the Berger 85.5gr and I’m happy.

Same story here pretty much only 90 MK's. Just couldn't make them work in 7.5 twist, only suspect bullets coming apart, 85.5's pretty good @3350.
I want to try 75's.

New to 22 Ceedmoor.
I just put a 24” 1-8 twist pre fit Proof on a bighorn action and bought Lapua 22-250 brass.
I’m fire forming them with 38.7 grains of IMR4451 and 90 SMKs. They are moving 3178 FPS and stupid accurate. It’s shooting .2s and low .3s. I never thought it would shoot that well fire forming.
It won’t shoot the 95s, holes aren’t round on paper, but with an 8 twist I didn’t expect them to.
I have 1000 of them so next barrel will be a 7 twist.
I haven tried H4350 yet, trying to save it for my 6.5, the way 4451 is working I won’t need to use my H4350.

Someone else with far more knowledge I am sure will have a reason but here is mine which is two fold. This rifle has 3 barrels 22 creed 6mm creed and 6.5 creed. I wanted to simplify how I was doing things therefor I built a switch barrel. Here are the other reasons that tossed me over as I have shot fast twist 22-250 Imp for a lot of years.
No fire forming, this was a major for me as I hated the thought of consuming barrel life fire forming, although in my experience i found they shot forming loads quite well, It was at a lesser performance then the formed cases. Also, losing a case on a stand was devastating after going through forming ect. I have found new brass vs once fired in the creedmoor difference in performance to be pretty well negligible
30 degree vs 40 degree shoulder. Although I was able to get the AI to feed well after some monkeying it is my opinion that the creedmoor feeds better.
I have not measured but I am told there is a slight case capacity increase to the creedmoor case. This was not a primary reason for me as again i did enjoy the 22-250 imp.
I also contemplated a swift as I have shot a few barrels in the swift, I gave the edge this time to the creedmoor as the case is shorter enabling me to knock some free-bore into the barrel for use with heavies.
Of course, this is my personal opinion and really only holds value with me. Like I said, Ive had great results with either so I really don't thing you can make a bad choice.
Thought I would update my findings today as I have been testing Lapua 6mm Creedmoor brass today with 4350
I tested the following charges in a 10 round pressure test and have yet to see any pressure signs, however this is as far as I will push it as I would like to do a test with RL26 today as well.

37.4 3155

It would appear there is a couple of flat spots to play in. I found that my FL sizing set up for the peterson brass was far too much at .004. I have since fixed my boob move and i am only sizing .001. I think that was showing some signs early for me on the first test. I will revisit but for now I will continue with Lapua.

Handloader Magazine #330, February 2021, has a fine article by Patrick Meitin on this cartridge (and a rifle), including lots of loads for 77- thru 90-grain bullets.. Available here. https://www.handloadermagazine.com/issues
Yes, load and fireform. They are a bit short and they do blow out a fair amount. If I were to use 22-250 brass I would say a guy may as well just do a 22-250 Improved.
Are you neck turning the Lapua SRP brass? 6 or 6.5? Thx, I’ve got some 77 TMK’s coming to try in my 22” Bartlein 8 twist. Using Alpha LRP right now
Negative, Ghostrider. Not turning necks. My reamer has a .2575 neck (GAP Spec'd reamer)
Sweet. GAP built mine so likely same reamer spec. I’ll check it out, have plenty of Lapua 6.5 creed SRP brass.
I have a few hundred of the 77TMK's to try in my .22 Grendel, but since my creed are running the 69TMk and 80.5 bergers so well, I wasnt bothered to look further. The 77TMK's will kill quite well in a 22cm, a buddy has been thumping hogs and coyotes with great results.
hey guys I need a starting load for a 22 cm,I just ordered a barrel form northland shooters supply,1-7 twist 28 inch bull barrel all they had in stock,Its going to screw on a defiance deviant action I have alot of rl-17.I have 80gr. bergers and 85.5 bergers .What would be a good starting load for this combination.Thanks Jeff
Few loads I’ve been working on with the 85.5 Berger’s.

I’ve been floating around the hide for a lot of years now and have enjoyed every minute of it. Every now and again I find myself having a hissy fit when I cannot find the information I am looking for. It has finally donned on me that maybe I should be a part of the solution and post the things...

How do you like your rig for thermal coyote hunting? I'm thinking about getting one in a AR10 platform as well. How is recoil and how does is suppress down? I have a couple .30cal cans I would run on it.
I love it for hunting. I’m zeroed at basically 75-225yrds to a dead on hold. 300 is top of back. I hit one at 380 a tad low but the wind on the nights we go out is under 15mph and not a thought.
I haven’t had any feed issues. I can’t run suppressed in my shithole IL state. I run a gen 3 APA brake and recoil isn’t even worth mentioning. The only downside is my brass getting beat up. Ejector swipes are rough. Hunting in the dark, in the snow my recovery rate is probably 40% at best so I caulk it up to the cost of business.

Sounds like you need a 3buc brass catcher on your rig and increase your brass recovery.
Yeah with the thermal, dvr, battery pack, and Radius I have enough gadgets hanging on this thing. Before the great brass shortage of 2020, buying a few hundred pieces and recovering 80-100 sounded fine.
Have you done some research on this? I was going to do the same but was talked out of it because so many guys were blowing up bullets using them.
using their barrel, using their FB, using their what? I plan on using a 1:7 twist with rl36. I only want around 3000 fps. I dont need a speed demon
1:7 twist barrel. I think it was mostly RL26. The long bearing surface coupled with the thin jackets people were having them blow up a lot, even when they backed them down under 3K FPS. Sounds like some did get it to work but most gave up on them. Good luck, I was going to go with the 95’s as well but because of all this had my new barrel hand throated for 88 ELD’s.
I had Keith at Phoenix Custom Rifles work out all that. I told him I wanted to run the 95gn SMK’s. He ordered the reamer and it’s a shooter. 1:6.5twist and no separated jackets so far.
Testing some new 22 creed brass. 10 shots at 100yds.
Stay tuned fellas, very exciting announcement coming soon!

VERY NICE! Care to share the specifics on the load data...
Sneak peak for you guys.
Alpha OCD 22 Creedmoor! Been working with a test lot of this brass recently and it has been amazing. This case pictured was hit with a 80gr Berger VLD Target at 3668fps, and then was reloaded 27 additional times with an avg velocity of 3515fps before the large rifle primer pocket lost the ability to reliably hold a primer. Drastically better than previous 22 CM brass from Alpha! Not available to the public yet, but keep an eye on Alpha this summer folks!
Absurd accuracy as well, with a 3-shot group at 600yds measuring under 3/4”. Some luck there for sure... but that’s still very cool to be able to do when testing this new brass from alpha.
I have it on good authority the production brass is even better! We have a full article outlining the performance details in the works and an update to our 22 Creedmoor cartridge guide as well. Stay tuned!.

When I zoom in on that primer I see concentric circles.....is this from the bolt face or are you using some whiz bang Primers as well?
Pretty sure that is machining marks in my bolt face on the Desert Tech bolt. They tend to not have a very nice finish, and as you can see by the massive primer crater... they don't seem to like having a good fitment between firing pin and its hole either.
