I decided to build a 22 Creedmoor before it gets uncool to have one. Barrel was bought on sale from J&A Outdoors and chambered by Black Canyon Customs. So far it’s been a straight hammer with Hornady Precision Hunter 80gr ELD-X factory ammo.

Kelbly Prometheus action
McGowen 18” carbon barrel
Manners LRH-NV
MDT bottom metal
NF NXS 3.5-15x50 ffp
TT Special 2-stage
TBAC Ultra 7

Planning to add a clip-on eventually.

Thanks man, it’s an 18” Bartlein M24 contour that SPR spun up for me. It’s heavy at 18 pounds but it feels like a 22 recoil wise. I have used a little Varget, 2230-C, Benchmark, N140, and 748 but settled on StaBALL Match for the convenience of ball and consistency of stick powder.

Running both the 75 and 80 ELDM’s with 26.0 grains at 2.500” OAL. The 80’s are running just over 2800 fps. I got the 75’s up to an average of 2960 using 26.0 grains of Win 748 but the SD’s were really high. Using Starline 5.56 brass and Rem 7 1/2 primers.

I thought that barrel looked like a thick boi.

That seems pretty fast for an 18" barrel, my Tikka was really slow with Varget, ended up with Benchmark and 73gr ELDs.

Yeah I have read that Varget is a bit slower in a 223 than some other good powders so that’s probably most of it. Is your Tikka barrel factory? I am at 2755 with Varget with the 75’s and 2721 with the 80 ELDMS. Not sure how close that is to your velocities.

Sounds like the StaBall Match isn't as close to Varget as I thought it was.

My Varget loads with 75gr BTHPs were barely breaking 2600fps whereas I ended up using Benchmark and am getting 2750ps with 75gr BTHPs and 2780fps with 73gr ELD-Ms.

Factory Tikka barrel which does appear to be slow from other loads I've tested.
 
Anyone tried a short barrel 6 CM? Just wondering if there would be any issues as opposed to a 6.5CM?
I have a 16” 243, so similar. Shooting light bullets for coyote hunting and it’s been awesome. I was shooting 58gr vmaxes at about 3300 and have since switched to 65gr Noslers. I haven’t even cronoed them but longest kill was 300 yards with my thermal.

Thanks. I had a 24” 6 creed and shot 108 eldm. Not sure how that would do.
What twist barrel are you using?
