22 creedmoor

I have a 1/8 twist 3 groove 20 inch with only 2-300 rounds. H 4350 producing 3196 via labradar with out pressure with 80 gr Berger vld.

My question is has anyone tried the N555 powder. I haven't found much info supposed created for the 6.5 Creedmoor.
 
I swapped a 20” Rainier Arms 22 Creedmoor barrel in a Seekins SP10 308. I am running 41.0 grains of H4350 behind the 88 grain ELD-M bullet. Shooting a hair under 3/4 MOA, seated .015 off. I am getting 3024 FPS. I can’t wait to see what group sizes do when I play with the seating depth. Barrel is a 7 twist. Brass is Starline 6 Creed Necked down with SRP and a Federal 205M primer.

I shot a one day match a couple of weeks ago with the 22 creed. The gun shot great, I'm very happy with it. I could see impacts at the 630ish targets 760ish targets and 815ish targets. I could see trace of the bullet every once in awhile. It was cloudy and windy out. Shooting at the 815ish targets, the 6 creed guys were holding .8 to 1.2 mils for wind. I was holding .6 to 1.0 mils for impacts. It does have a little less wind drift then the 6 creeds and less recoil. Round count is 244 and no throat erosion. Where the case mouth is in the chamber does look a little beat up.
 
I am getting a 22 creed built as we speak and was seeing that a lot of people are using RL26 and I don’t have any but I was able to get my hands on some N565 and both powders burn about the same rate and was just seeing if anyone has experience with the N565 in the 22 creed
 
N550 will get you 3500+ with the 75 and 77gr bullets re26 probably better option if you can get it. The n5 range is *apparently* nasty on barrels
 
I have about 600 rounds down the tube on my 22 Creed now. This is a Hawk Hill 4 groove 7 twist. And its been a learning experience.

I put a 150 rounds through, developed a load and took it to an NRL match. But apparently it wasn't done speeding up yet. My developed load was 41.7grs of H1000 @ 3130fps, it was doing 3170fps by the end of day one and 15% of my 95gr SMKs were having jacket failures. It was a mess... a 207 round count match and I popped over 30 bullets. I had several stages where 3 of 10 rounds failed.

Reworked the load when I got back home to something slow. I dropped to 40.4grs of H1000 @ 3020fps. I shot a club match last Saturday and it shot lights out. A stupid mistake (I dropped my mag running from one position to another :( ) cost me the win.. and that was with 6 Creed brass resized down to 22 Creed, but unfired.

This 7" twist simply won't let me push it into those high velocity "heavy wind gun" velocities. So I need to decide if I'm going to keep it in that velocity range, or possibly experiment with the 7.5" twist that will let me drive it around 3150fps. Gotta weigh out that loss in BC versus the gain in velocity.
 
26" Shillen 8 twist and starline 6.5 creed brass necked down and neck turned
Lab radar has always been right in the past, I suspect the velocities are correct.
47gr of r26 and a 77gr custom competition is amazing except, this summer in a prairie dog town I discovered its too hot and its tearing up my brass, too bad I loaded up 300 rounds of them and now gotta wait till winter to shoot them again.

Yes this powder works well. works as well as H4350 and is typically available due to the fact this powder cost more. I shoot it with 80vlds 41g and getting 3,400fps from a 26in barrel. its a slower burning powder you will need a grain or 2 more than your same h4350 load
 
At 750 rounds in now. Ive only lost .006 off the lands.

I bumped the freebore out to .250" so I could get that long ass 1.288" 95gr SMK seated above the shoulder juncture. Its shooting really well jumping .110" over H1000.

Anyone have any feedback on barrel life in PRS usage? Thats what I'm using this for, but there's been a lot of experimentation with this barrel. I ran some pretty hot loads at first. I'm going to try to keep it between 3000 to 3050fps and see how long it lasts from here out.

If you've only lost .006 in 750 I'd think you'd have at least another two day match or 2. H1000 might extend it longer. What barrel specs are you using?

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.

Thats a 26" Hawk Hill 7" twist MTU.

I'm curious to see if it will reasonably shoot 1500 to 2000 rounds using the H1000.

Had a long chat with Scott Satterlee over dinner at the last NRL match. Collected all his thoughts on long freebore and barrel wear. He's getting 2500 to 2800 rounds from a 6 Creed with crazy long freebore and 2900fps. I cant remember what bullet he's shooting, but I think it was 115 DTACs. So I pushed out my freebore and jump, I'm running a super slow powder, and I'm slowing the round way down. It'll be interesting to see how long it lasts.

Love me some hawk hill. I think 1500 is possible with mild-med loads and h1000. You'll probably start blowing up bullets before velocity and accuracy loss.

I've already done the jacket separation gig. At 3170fps and a hot day, its a bullet poppin' fool 🤣

I dont think it'll have jacket issues at the speeds I'm running it now.

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.

My SAAMI spec reamer is an .080" freebore. So I'm right there where you're at. I reamed that out to .250". Even at .110" jump my 95's are seated above the neck juncture.

Scott has experimented with his 6 Creed all the way out to .350" freebore. But I don't think he stuck with it. He's back in the 200's.

I plan on running this barrel hard all through the winter and replacing it in the spring. I'll keep it and swap it on and off until I absolutely kill it. I'll figure out how far I can reasonably stretch it.
 
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.

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.
 
Howd
Completed a test with H4831SC. Found a good nodes between 40.2 and 41.1gr.

40.2 - 3076 fps - SD: 6.8 fps ES: 16 fps
40.5 - 3085 fps - SD:11 fps ES: 21 fps
40.8 - 3084 fps - SD:2 fps ES:5 fps
41.1 - 3098 fps - SD: 4.6 fps ES: 9 fps

I am at 0.010 of the lands( 2.778 coal) with the 95's. Groups are not too bad 0.5" at 200 yards.

How’d the 95 gr SMK perform long term?
 
Any update on how this load fared long term?

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

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.
 
I’d say factory brass, other than that probably nothing.
 
What’s the advantage of 22 Creedmoor compared to 22-250AI? Honest question.
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.

Grains Velocity FPS
37.2 3129
37.4 3155
37.6 3159
37.8 3179
38.0 3181
38.2 3215
38.4 3200
38.6 3220
38.8 3249
39 3252

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.

With the 22-250 brass, do you just load and go? Does the brass come out a little short?
 
For the 65, you will want to run Varget instead of the H4350. We run the 69tmk with 39.0gns of Varget and its magic. 3510fps from 20" 9tw. Nearly identical speeds from that load in more than one 20" rifle. You might have to "stand on it" to get the 3600. I would strongly recommend the SRP Lapua brass for that and stay the hell away from Alpha brass, it shows pressure signs way before the Lapua and doesn't give the speed. That is not just my findings either.

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
 
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

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.

what barrel twist are you using
 
What free bore are you guys using, looking at preferred barrels and for the 95smk they cut .160 fb.
I only plan on shooting the 95smk. So should I follow that or change it?

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.
