The 22 creedmoor thread

[mtnbound]

Here's my actual fps and then what GRT calculates with a Sebert factor of 0.5. This is with a 16.5" barrel (PVA 100FB) and a Scythe Ti suppressor.

39gr of H4350 in my 18" was 2980fps. I started seeing faint/light E marks at 40gr, and a heavy bolt lift at 41gr. I dropped back to 39gr and called it for H4350. I went to 40.5gr with N555 at 2940fps and no PSI signs,

I've also settled at 39gr H4350 with the 88s 3075 fps 20"

I contemplated building a 22 creed specifically to run 69 eldvt for thermal coyotes/fox with the intention of saving fur. After reading this entire thread, thinking I'd be better off sticking with 223. Mostly bc my thermal has a rangefinder & ballistics and to avoid big holes. 53 vmax has been a great yote killer but they won't shoot in my tikka. What bullet would you guys recommend i load up ?

I’d try the 55 blitz king

What about the eldm’s in that weight?

I use the 50 grain vmax for night hunting a lot. Never tried them in a 22 creedmoor but have shot lots of them from 223s and 22-250s.
Not too hard on fur if you stay off bone. They obviously aren't a high BC bullets but for calling at night, that usually isn't top priority.

The 55 blitz has a chance, I'll snag a box to try. The gun especially hates 52 eldm. I suspect it just doesn't like low 50's.
The thing shoots 73s and 77's very well. Might also try the 60 tmk- wish they made a 60ish eldm

I tried out N560 in my 18" 22cm today. 43gr-45 grains on ladder. I had slight heavy bolt lift @ 44.5gr and a heavy bolt lift @ 45gr.
I had 5 rounds loaded @ 43.5 gr just on a guess, based on other powder pressure tests. Sure enough, it's about where I'd want to be with N560. 5 shots were about 3/4" @ 100 which is worse than the gun typically shoots with H4831sc. I also had 1 shot that was low on velocity compared to the other 4. Maybe i slightly under charged, i do not know.
I am going to load up 20 rounds today @ 43.5 grains and see how it groups and also determine if it was indeed a little erratic or if I under charged a rd.

I gained 100fps over H4831sc at similar pressures, but initial accuracy test, albeit only 5 shots, appears to not be as accurate. I was hoping for more speed out of these 77's, but I think 3000-3100 is where this barrel is gonna top out at safely.

Agreed - if you're looking to save fur, I wouldn't go 22 Creed. Honestly, for foxes, 223 might even be too much depending on the projectile. Those things are so thin skinned.

I had read enough good things on the 53 gr Vmax that I figure I'll give them a try in my 223. Going to pull the factory barrel soon and replace with a proof prefit that's been sitting on my shelf for a while now. Might even punch that out to 223 AI for a little extra oomph.

Since your rifle doesn't like the 53, I'll second the recommendation for the 55 blitzking.

Well not really a big ask in the 22cm
But data is data

62gr eld-vt
47.2 gr N555
Peterson LRP
Fed 210m
24” preferred barrel 1:8 twist
20 shots averaged 3820fps.
It’s 1 mil flatter and same wind hold as 80 eld-m at 750.
It was about 50* this morning
If I was hunting a lot of coyotes this would be my main bullet/combo

I'm running Alpha brass which I guess just doesn't have the capacity of your Peterson brass. 47 grains fills my case to the very top. It would be a very compressed load. Is that load compressed in your Peterson brass?

It’s not compressed in Peterson
Alpha has the least capacity, normally 2~ grains less than Peterson

Not quite 22 Creed, but close enough:

I like to tinker and thought I'd try the 53 gr Vmax out of my 1:8 22-250 AI. Loaded a few to check pressure with RL-15 and took my can off in case RPMs were too much. Using Sierra 22-250 AI data, max of 38.8 gr yielded 3615. Better yet, all bullets made it to the target without issue.

I loaded up a few charges this morning to see how they group. Going to see if I can push them to ~ 3700. Assuming these shoot well, they should be pretty rough on varmints/predators.

Finally got a chance to test the 22creed on some axis deer. Using a tikka with 18”pbb barrel from lswild. Shot 4 and all of them dropped instantly from ranges 170-340yds. Being able to spot all the impacts was awesome. 80.5bergers going 3050 in peterson brass. I did use a small drill bit to ensure hollow points were clear to allow bullet to function properly. I’m sold on the caliber for the hunting we do here and will definitely use it more often.
