22 creedmoor

I thought I'd try a 22creed, seems like a neat rd. Nuke 2.0 action, 26" varm criterion 7tw barrel nut, Peterson srp 22creed brass, cci450, h4831sc and 95smk. Started load testing today with 42.4gr set as max, with plans to go up if primers looked alright. Bullets are set .020 off rifling as a generic starting point. Anywho, 5 powder weights/3rds per weight just to see what it will do. Ground was saturated and bright sun/60° with 4-5mph wind= some mirage and soup to deal with.

Everything was going fine until first rd of the 4th powder charge. Bullet didn't impact as predicted. As I scanned target in that area, I then saw a large rip 4" low and 3-4"left of aiming point. I shot the next 2 rds and they landed as predicted. Shot the 5th charge weight and those rds performed as expected.

Has anyone saw or heard issues with 95smk? I generally assume keyholes are too slow fps/too slow twist. I had no issue at slower/lower powder charges. Barrel was allowed to cool to ambient before string. Got any ideas?
I’ve ran into a similar issue. I have a 7 twist criterion pre fit and I wanted to run the 95 smk and I did but with the occasional issue that got more common as the barrel wore. So I switched to the 90 smk and and I ran great for awhile at 3280fps until I had some start hitting sideways or huge poi shift. I talked to Sierra and they said the 95 smk was designed for long 223 barrels with max velocity of 2900 fps and the 90 smk was designed for the 224 valkery again 2900 or less. He said with the thin jackets you are more likely to see issues as the throat begins to fire crack. This is on point from what I saw.

95gr SMK’s at 3080fps got me my first ever top 5 finish in a PRS match last Saturday. I could hear the RO’s while I was shooting saying “that thing is a laser beam”.

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 .
Hmmm One of these cases, is not like the other


hey, I got one pop quiz. How do you increase your velocity by 150ft./s without adding any powder super cheap way to increase speed.!!!
NOT…


I wouldn’t max charge any round before you work up to it but hey, do what you want


federal cases are not top quality like Peterson and I’m willing to bet that Peterson would easily take the pressure


I found the main culprit=.
Neck tension= not sure how these were so work hardened but damn couldn’t get them out with a press mounted, collet bullet puller w/o destroying or severely marking the bullet.

A tight reamer /the neck area probably needs a few .00’s than what it has.

all Schilling barrels that I have, that are chambered by Schilling, have a very low thousand space between the neck and the chamber wall . (too bad about the spelling, but I can’t spell it. I’m not going to.)


should have anesled it and maybe even cut a few thousands off the neck


What an interesting learning day I had
Happy I didn’t flame-cut defiance bolt head

I’m sure there’s difference in case volume as well why one was OK and one it wasn’t..

This is my favorite rifle, too. I've worked up a couple different loads with slower powders. I'm currently shooting a rifle I built with a Bartlein 1:7.7 twist M24 taper with a Brownells Stryker Ridge action (made by Defiance) in a Manners EH1. I'm about to replace the barrel in this rifle after approximately 800 rounds. Note, I shoot it like I stole it. I'm rough on my barrels but since I can rechamber myself I don't worry too much.

All are from 26" barrels (two different rifles) and CCI200's and 6mm Hornady brass. I've got 100 pieces of Lapua 22-250 brass that I'm fireforming now with 38 grains of R26. Simply load the 22-250 and shoot. Nothing needs to be done to the brass before fireforming. I've yet to work up a load with the Lapua brass. All velocities measure with a MagnetoSpeed.

Sorry for not following the format outlined. But, what I've found, is that if it works in the 6 Creed with the 105 Hybrid it works fairly well in the 22 Creed with bullet weights from 75-82 grains.

75 grain AMAX - Note, I didn't shoot these but gathered them from a couple others that did.
46 grains MRP. Over 3500 fps.
45 grains 4831SC. ~3500 fps.
45 grains R26. ~3650 fps.

77 grain Sierra TMK
41 grains R26 - 3130 fps, 42 grains produced a decent crater in the primer
45 grains 4831SC - 3320 fps. I use the same load in my 6 Creed.
45 grains MRP - 3545 fps, SD 11.8

80 grain ELD-M - There was something about this bullet that didn't work but my notes don't tell me what that was.
48 grains R26 - 3650 fps. Decent 100 yard grouping, 1-1.2" at 200 yards
49 grains R26 - 3750 fps. I did no accuracy testing.

82 grain Berger
45.5 grains 4831SC - 3517 fps. 46 grains had no pressure signs. I shoot the same load in my 6 Creed with the 105 Hybrid.
45.5 grains R26 - 3540 fps. SD 8.1. I shoot the same load in my 6 Creed with the 105 Hybrid.
45 grains MRP - 3400. good accuracy. I shoot the same load in my 6 Creed with the 105 Hybrid.
46 grains MRP - 3515. Good accuracy at 100, horrible at 200.
Has anyone had any luck with the Hornaday 75 edlm s In their 22 CM I have some Berger 80.5 but Hornaday is cheaper?
 
For those looking at which twist rate they want IMO I would avoid 6.5 twist. IMO I think 7 is too fast as well. My next 22CM barrel will be an 8 twist. I shot 88 grain ELDM's and I was stuck at 3200 FPS and the reason was RPM's. When deciding on a bullet and if you have an idea on velocity then I would calculate RPM's and make sure you are okay with rpm's and velocity. I was blowing up rounds in a new barrel because of RPM's. Good luck. Also a quick phone call to the bullet maker to find out what RPM the bullet can handle can save you some regret.
All of this is my experience. Your experience may vary. Good luck

That’s good to know! Mine is a 8 twist 22” barrel with the 75 Gr Hornadys @ 3440 FPS
This is a copper creek load I haven’t started a load yet was going to try H-4350 large rifle primer and Peterson brass

Ok thanks good information I will be running a 8 twist in my 22 CM I will be running 75 to 80.5 bullets I think these are perfect weights for the 22 CM

7 tw for some 90gr bergers, they seem to be the only heavy bullet thar won't eat itself at more than 3100fps. 24" 7tw slings 90s@3230, my 22" 8tw sends 75gr@3430.
I've shot prob 400 hundred 85.5s through my 7tw osprey blank, no issues. Ran 75s at 3250 without problem either. Velocity is lower tho as it's an 18" barrel.
 
I have shot about 200 90 grain sierra's at 3100+ fps without issue in a 26" 7 twist Osprey. I will soon start working with 95 grain Sierra's and hope for the same results. The only bullets I have had come apart were 147 ELDM's in my 6.5 PRC.
The 95smk is fine at 3000 max. I had issues with them randomly in a new 7tw barrel. Thinking since it happened at several different velocities(3020, 3110, and 3180) sporadically, it must be a bullet lot issue. Sierra ballistician I talked with flat out said those were designed for 223 and 224valk, at their speeds. In a bigger 22 case they would desinigrate.. I mention I'd saw several guys post about it working, to this he laughed and said "for now, let them get a little throat wear and see how they like it." If it works fine, but it isn't gonna work long enough to wear out a barrel. I can see it being good for a short barrel that will not be over 3000fps, but handicapping a 26" pipe to 3000fps with a 95smk or rolling a 90gr berger at 3230 is a no brainer for me.
 
So far 95’s have worked well at 3080fps in a 7 twist Mullerworks for me.
I wish you luck, maybe with fresh barrel and 5r type rifling, they will hang together for a little bit. I found the 90hr berger to be more accurate and easier to load. The bc difference, at same speed, wasn't worth the hassle and blow ups. Factor in throttling back the 95smk and the bc wasn't worth it.

Barrel is now in the corner and replaced with a 6.5x47 barrel. I may dabble with the 22 Creedmoor down the road if I want a bolt action coyote rifle instead of my AR-10 .243.

Thanks for the info. I believe the Sierra representative. I also believe, as stated before on this site that the bore size has a lot to do with it. The osprey is .219 as opposed to say a Kreiger which is .218. I have 15 rounds loaded up to test in my rifle that currently has 462 rounds through it. I'll report back on the results.

Have you done the analysis to see where differing twists, RPMs, speed, BC, and stability intersect? Like how much is the BC degraded? And does it make a difference in wind error forgiveness at distance? Or does it matter so much that a person can shoot a lighter/ shorter bullet with a poorer BC faster to make up the difference? Just curious; not a loaded question.

As far as twist rate and rpms go it's completely agnostic of bullet weight or length, barrel length, or altitude. It pretty much establishes a glass ceiling of top speed. But stability can be managed by twist rate, speed, and altitude at the cost of BC. I guess the question is: At each individual persons altitude, what is the BC cost of keeping the 95 SMK below 300K RPMs? Whether by speed or reduced twist? Is that BC cost negligible in wind drift at distance or is it considerable? And then finally, if you self-limit to another sturdier bullet, are you still limited by speed and does that bullet have an optimized BC that is better than the 95's degraded BC?
All I'm saying is that the 95smk, according to Sierra, was designed around 223 and 224valk speeds. That's 2500-2900(maybe optimistic), you start hammering on them in a creedmoor at 3000+ and it's a crapshoot on whether they stay together. And if they work today, there's no guarantee they'll work in 400+ rds of barrel wear. My point was the 90gr berger hangs together up to 3300 in a 7tw 22 creed, shot better at 3230 so I settled there. In over 100+rds, I've yet to have any weird impacts, just where they expected to go. The 95smk, I had 3 or 4 out of 24 not get to the target or land sideways(jacket presumably starting to fail and causing yawing). That happened at low speeds of 3050 and a higher. No amount of hoping will make that work.
 
Using just the best bc of Sierra's banded bc range(which I'm not going into that) at 3000fps at 1000 in a 10mph fv wind it's 7mile drop and 1.7mil drift. My load of 90gr vld at 3230(which shot better than 95smk and never lost a bullet) is 6.2mil drop and 1.7mil drift. The 95smk might need to be slowed to 2950 or a bit less to remain intact past 50yds, and also a 6.5tw barrel, now it's 7.3 drop and 1.8 drift. But hey it's probably gonna not fly apart, so there's that.
 
I know several folks including myself have been playing with the 22 creedmoor for a while now. Please keep this thread to actual reloading information, and if you can please post some round count, barrel life numbers are all over the place.

Here is a brief summary of the cartridge. You need to know that it is a laser beam and varmint vaporizer! The 22 creed feeds awesome out of a aics/aw mags, has increased case capacity, and can toss 80gr pills over 3400fps. Also, you can use youre existing creedmoor die sets with a different bushing and seater or call up whidden and get a custom set. Using 6mm creedmoor brass is the easiest way to make brass, but some have fireformed 22-250 brass into 22creed.

Please follow the format of

bullet/ weight/type
powder
charge weight
primer
velocity
barrel make, twist , length
round count on barrel
any other info, fowling, groups, effects on game or varmints

thanks for the information
Just shot 41 grains of h4350 no signs of pressure wonder if I could just jump to 42 grains or just go up a half of a grain using 6 cm lapua brass 450 primers 75 edlm bullets.
 
80.5gn Berger Fullbore
43.0gn H4350
Fed210M
Unknown velocity as of now
Rock Creek 8tw @22"
Melonited Defiance Deviant Hunter
Chambered by Beanland
Running an SAS Barricade
Shooting multiple 1/4-1/2" groups in load development
Killed 3 yotes and 2 sows @ ~200# each from 90 to 306yds. Only one yote ran about 25yds, everything else never took another step.
about 50rds on the bbl
For brass you might look into Alpha Brass. I believe they will be doing a full production run of 22 Creedmoor in the next 45-60 days if not sooner.
I was breaking in my 22CM with lapua brass 41 grains of H4350 1/8 twist 75 grain edlm bullets don’t know the freebore forgot to ask gunsmith just told him to set it up with that bullet just wondering if I could jump to 42 gains or no . 41 grains showed no pressure signs .
 
For what this is worth, my load above shoots great with Hornady brass but as with most tinkers I wanted to try some loads using small rifle primers. I bought some Peterson 6 Creed brass ( seems to be very good brass) and have been trying to use RL26 with CCI 400 AND 450 primers and it's been very unfulfilling with wild velocity swings. I will try again later using faster burning powders but for now back to the proven.
what load & powder does anyone use for the berger 85.5 ?
 
I have had the most outstanding experience with The Urbanrifleman ....ordered my barrel for my 22 Creed on Saturday
a 1-7 and decided to give him a text and ask to change it to an 8 instead....He contacted me this morning and we talked for 90 minutes ....a super guy ... He literally contacted me 4 hours later with pics on my phone of my new barrel...
Barrel is 26" ...max speed..
He literally treated me like family and completed it immediately and mailed it overnite , I'll have it tomorrow...

anyway....I am gonna work up a load for the yotes .. Have superformance and Power Pro 2000 MR to play with
as well as WW760....Alpha Brass , Hornady 75 Gr ELD M , Sierra 69 Gr TMK ,

Anybody have any load data for these combos ??

After doing my research I thought I'd share a bit for others ...

Here is a link to Vihtavuori Load data site for 2 Creed....
If you have a powder and cannot find data for it in 22 Creed
determine what VVN powder has a similar burn rate and start
from their data and go low and slow upward...

In my case Power Pro 2000 MR is same as N550

so here is Sierra 69 GR TML
