Well wtf?! Only one the best powders ever. I wonder why.......def wasn't for lack of sales.
It has arguably one the highest energy contents out there. Glad I have 10# of same lot left over.
Has this been officially stated by the company somewhere (the stopping of manufacturing)?? Sucks if true.
I have experienced more hang fires with this round than any other, I was using Federal AR match primers because that is what I had the most of. Switched to CCI SR magnums and haven't had anymore trouble.
I'm really surprised more hang fires isn't reported. Remember years ago working with the 22 CHeetah using the old F.L. Remington BR brass and small rifle primers, till we hit near maximum loads we had hang fires especially as the weather got colder. Changing over to 243 brass and large primers the problem went completely away. Guess the powders today may be easier to ignite.
I've got around 500rnds through mine and havent had one hang fire, SRP Lapua brass with 4831sc
That is very close to my load, I am using 90gr bergers with 43.5 gr of 4831sc at about 3200 out of 26" barrel.
My 18" 7tw will be done next week. Running tbac ultra7. Have 200x pcs alpha ocd brass. Will be running 85.5 bergers as I picked up 1k of em last month. Also have 88 eldm and 75 eldm to run. My last barrel was 22" 8tw running 77tmk at 3400 fps with N555.
Looking forward to hearing more.
I’d be running similar with an ultra 7 but would probably go 16.5”. 80.5, 85.5 bergers and 77tmk. I’m wondering where velocity will end up, I don’t want 77s going too fast for shooting deer, but a little more steam than my current 223 in a much shorter package would be awesome. Plus the ability to run a heavier bullet for coyotes and prairie dogs in the wind.
85s will go 3100 I'm sure, 88s will be mid 3000s. I'd assume 77s should go 3200+
I was getting bad carbon ring with 4350. I switched to retumbo being the slower burning powder to help alleviate the problem. So far so good but only a couple hundred rounds down the tube.
Believe it was around 44gr, 3500 was 45.5, it's a bulky powder and I used a drop tube.
16” 22 creed
88’s @ 3040 fps
80.5 @ 3090 fps
75 eld’s @ 3110 fps
H4350 used. I’m not home to pull actual charge weights. I jump them all .050”
This barrel has roughly 900 rds down the tube and is still performing at acceptable levels (no bleed off and 3/4” moa with the occasional 1/2” moa.

Results from my 22 creed build.
18" bartlein 1/8 .219 rem varmint. Chambered by straight jacket
75g ELD-M
alpha non ocd brass
cci 450
2.100 CBTO
42g H4350
ran 41-42.5g through the chrony and settled on 42g going 3287 (one of the first 20 rounds through the barrel) hoping it settles down around 3350-3400 once broke in.
immediately went and sighted in with my thermal (to get going on the early season) and it bugholed 2x 5 shot groups. Since then i have shot less than 10 rounds through the rifle and have 7 coyotes on the ground anywhere from 75yds to 340yds (1 was a runner i shot at 3 times). This setup HAMMERS for night hunting.
once i get 100 rounds or so on it i'll measure the lands, check for any signs of carbon ring, and see where my speeds are, if necessary i might lower the charge a touch to be a little easier on it

What is ideal freebore for 88 eldm 90 atips? I have a 22 cal throater, but smiths reamer is 0.100fb for lighter stuff. I went 7tw 219 bore diameter on the barrel. I have a pile of 85.5 bergers, 88 eldm, and 90 atips.
I took these measurements back when my barrel had 400 rds on it. Thought I’d share…
22 creed data
400 rds down the pipe.
Projectile with the blue is just touching. The projectile without sharpie is a dummy round .015” off the lands from the barrel when it was fresh. Roughly .060” throat erosion. Typically from what I’ve seen with less aggressive cartridges (non overbore chambers) and what I’ve read, .010” is typical every 100 or so rounds.
So essentially my findings bring me to .015” erosion ever 100 rounds. You gotta pay to play.

0.015 per hundred is quite aggressive, truthfully, the worst I've heard. A 28 Nosler running N570 is around 0.011/per hundred in findings with 2 barrels burnt. I didn't notice near as much as youre measuring on my first 22 creed barrel. I think I burnt maybe 0.025 in the first 400 rounds and just quit measuring as it still shot the 77s extremely well at what was 20k off at 400 round mark. I will have to pay closer attention to my new barrel.
I’m limited on resources (I.e measuring equipment that would provide an absolute). That said .004” difference (essentially the thickness of a piece of loose leaf paper) from your 28 Nosler seems logical….
One to many variables at play to say my results are typically. Cadence of shooting, barrel composition, etc. I believe for my intended use without neutering the cartridges capabilities, an 18” with a slightly slower powder would be the ticket (3125-3175 ft ps with a 75/85grain pill).

Getting components for something I am going to try, a sig cross and rebarrel it. Get some srp Peterson 22cm brass, have rl26 and some berger 90s. Coyote and deer gun.
Thinking of a 20" but will consider 22 IF it nets me a lot more fps. It's a lightweight build I am looking to do, so either a fluted or cf barrel. It will be suppressed 100% of the time.
Has anyone ran solids in these? Hold up better to high velocities over copper jacketed?
Anyone have a reamer they suggest?

73 gr absolute hammers, 3700 fps with a case full of rl26 in a 22" 8tw barrel. Shoots very well! Killed both my antelope and a mule deer with them last year. Bc is dog shit though. Have a new 7tw barrel at 18" and am eyeing the badlands bulldozer 2 70gr bullets for that.
I kinda went after the bergers due to high bc. But 3700 fps is blow my mind speed. "It doesn't need to be aerodynamic when it teleports to the target" kinda speed. I have a 1:8 twist 22-250 with a 22 inch barrel but it does not seem very fast. It might get rebarreled or at minimum rechambered. But my initial post is for an entirely different gun.
I have a 22 Creed coming. Here are my components. Curious where you all would start?
Alpha SRP brass.
CCI 450's
Berger 85.5's
The powders I have that I would like to use are H4350 or H1000. I have RL 26 also. But I use a lot of that for a few other cartridges and would rather not use it for the 22 Creed.
Any suggestions on starting points with H4350 or H1000?

Load development with rl 26 done, 48.3, should make some 90 grain bergers fly.
Alright, just kidding, don't even have a barrel or a rifle for this brass yet, but hope to soon find a good deal on a sig cross in first light camo and either a fluted 20" or carbon fiber. Looking to make a decent, but lightweight hunting rifle for yotes and deer. Time will tell.

Id skip it in favor of 219 in my opinion, I also prefer 237 vs 236 in the 6mm options. My 18" osprey 219 bore 7tw with 40gr H4350 is moving 75eldm at 3050 and very accurately with no load development other than seating depth test. 39gr H4350 is moving 85.5 bergers at 2970. Not quite as accurate but 3 of the seating depths are under moa. 10k and 35k off with the 75s were near 1 hole groups.
I was not sure if I would hit pressure early with a tight bore, I imagine I would. It's just tough finding a barrel in my profile and twist range. Might just have to custom order.
Tikka T3x
PVA Osprey 3B 16.5”
88gr ELD-M
Alpha Brass
Federal 210M
40.0gr H4350
2.700” COAL
Velocity: 3050
88gr ELD-Ms were “splashy” on my Montana bull elk. Impact velocity was >2900. Bullet entered shoulder and completely shattered/separated the scapula from the rest of the leg bones. Led to a noticeable amount of meat loss. Heart/lungs destroyed. No exit. He didn’t even make it 20y after being shot.

Running 75eldm from an 18" 22cm. Loads sub moa at 400y with minimal load development. Running 3100fps. Shot two mulies yesterday . First was large body buck at 275y(2600fps impact), in the shoulder crease, did a 50y death sprint and piled up, massive lung trauma, deer bleed out profusely from the mouth before I got to him, no blood as I cut neck, it was all in the boiler room and on ground. Nickel entrance through a rib, exit was quarter size throug a rib. Next was another medium body buck, 475y(2250fps impact), strong crosswind, but my nephew who's never killed a deer, put the bullet at the neck shoulder junction, pencil entrance, quarter exit. That deer was lights out. I was impressed. I have quite a lot of the 77s as well, and may try some. This load is no pressure, and is only 40gr H4350 I feel another 150fps is on the table. I only have 65 rounds down the pipe so will likely gain more speed, however initial 20 rounds were 3050, now its at 3100.
Edit, put another 55 rounds down the pipe today, loads now running 3160 fps. Barrel has been heavily cleaned 2 times. Minimal copper/carbon fouling. I just feel. An 18" barrel picking up 110fps through break-in seems a bit much.

How are guys running 42, 43, 44 grains of H4350 with a 75 eldm? I'm shooting a 20" bartlein 7.7 twist with a .080 freeborn and a .257 neck. This puts the neck shoulder junction at the start of the bearing surface of the 75's and a .010 jump. I'm hitting pressure at around 39.5 H4350 in Peterson brass. What could be different?
Well i have a similar chamber, running 40gr H4350 from an 18" barrel at 3150 fps and my primers are still round, alpha brass. Peterson has the least capacity of all choices, so guys running 43gr in necked down Horandy, well that makes a huge difference on pressure. Also depends on your action, running a rem700 vs a Bat or Borden makes a big difference. Getting bolt lift could be from many things. How do your primers look?
3265. Primers looks good, but getting ejector marks. I was using hornady 6 creed large rifle primer brass before and I think I was hitting pressure around 41.0. Are guys running 43-44 grains running super long freebores?
I’m not running that powder, I’m running 4831sc with 90gr Berger’s around 3225, boat tail junction above neck shoulder but running a bit into the lands so not excessive FB. Hornady brass is trash. Ur Alpha brass should be good, how much you bumping the shoulder?
My predator load is 36 grains of H4895 with 60 vmax in an 18" barrel right at 3700fps. Barrel won't last long but I don't shoot but 50 rounds a season so it really won't matter
I noticed h4350 pressured out pretty quickly in my last barrel, 22" with 77tmk around 3250, 42ish grains, I switched to a lil slower powder, N555 and had great accuracy at 3350 and 3450 in lapua brass. I only shot 77tmk in that barrel so I throated it from 075 to around 130. I also highly recommend a 219 bore vs 218 bore to reduce pressure. Also I've noticed alpha brass can/will have ejector marks first firing if there's a lot of case growth. A rough ejector plunger or overly excessive spring rate on the ejector also can cause this. If you cant depress your ejector with your thumb nail without excessive force, I recommend trimming a few coils off the spring. Are you getting flat primers? How much if any growth is occurring at the case head/web area? Ejector marks aren't always a sign of excessive pressure. Have to check elsewhere too. Alpha has thick necks, its 254 loaded diameter according to my micrometer, that doesn't play well with the traditional 257 neck chamber. Can you slip a bullet into the mouth of a fired case with minimal to no resistance? If not, neck turning may be necessary. My smith uses a reamer with a 259nk and 225 freebore diameter due to the quick rate of carbon accumulation of the overbore cartridge.

Needing some assistance with selecting a bullet and powder. I have a 22" carbonsix 7.7 twist I bought for coyote hunting. I have 53vmax, 60vmax, 69smk, 75eldm, 77smk, and 85.5 bergers. I'd really like to stick with something that will run fast and flat if they won't blow up. Powders I have varget, 4350, and h1000. So far it's looking like 75eldm and h1000 would work pretty good from what I'm reading. I'd definitely like a full case with good speeds.
75’s and h4350 are your best bet. I haven’t ran anything else that comes even close. I’m a 25” barrel though.
