Here we go again.
Explain to us idjits how a 22-6creed barrel is going to significantly outlast a 22-243 one given equal velocities from both...?
I hadn't read that 22-250/22-250AI has trouble feeding from an AICS mag before.
Lower PSI, We are achieving the speeds with less powder charge and a completely different powder then a 243. The burn is cleaner. As I have stated multiple times, we are still testing. But as of now, the barrel is looking good.
3400 fps is a mild load for this, I could run it upwards of 3550 that showed no pressure signs.
You guys can hate and doubt all you want but this is factual. Myself and a couple others have the rifles and are shooting it. This is not a 22-6 Creed. It is THE 22 Creedmoor.
Ask George his opinion...... because that came straight from him.
But we all know if you don't read it on the interwebs, it can't be true!!!! Some people may have success but with the 22-250AI you have a really steep shoulder and that can give you fits on a feeding ramp.
I run a 223AI with 90gr Bergers, loaded long. I cannot single feed them and have to modify my mags to fit them. I only get about 2750 out of it but its a blast to shoot. When I want speed and low recoil, I grab the 22CM.
The feed issue could be easily mitigated on the 22-250AI by going to a 30 degree shoulder instead of the 40, you're going to custom order the reamer anyway and you're going to fireform anyway, so it's pretty much a wash.
Additionally, you now have 22-6.5CM equivalent with the option of just fire forming Winchester brass into your new wildcat anyway.
I looked REALLY hard at going to a 6-250 "modified" before the 6mm x 47 Lapua, but not 40 degree improved, just basically taking the nose of a 6mm BR and sticking a 22-250 case onto it. That's pretty much what you have from the 6 SLR but held about 0.14" short.
Ultimately I chose the 6x47 over the 6 Creed, 6XC, 6X, 6 SLR, etc etc for a couple of logistics reasons, not the least of which being that I acquired 600 pieces of brand new "Gold Box" Lapua brass at a screaming deal from a friend who is no longer in need of it.
This is not a new concept, it's been around the block a dozen times in various forms. High Power guys have been settting records and winning matches with the 6/250 and 6/250 modified now for at least 20 years. I ran across an old PS article from 2002 discussing how to make a 6/250 upper run reliably for space guns in the AR-10 because it had been so successful for the previous DECADE in bolt actions.
wasn't doubting it just was wondering what the final barrel life is. Also nice shot . How long of a barrel you running with the 223 AI to shoot 90gr? 6.5 twist? Can you show pics of both?
I suggested this round on another forum, posing it to gunwriters if Hornady might do a 22 and 6 CM. Personally, it's hard for me to justify a build of a barrel eater due to costs. If I want 2k bore life, I will buy a 243 or 22-250 factory, if I build I want a 6BR for bore life, but if a hunting only rifle, would consider a XC. A 22BR would have been a great round had Rem pushed their own BR line, esp in 22 and 6, WITH Appropriate 8 twist bores. Given choice I would probably choose a 22-250 or AI w/8 twist for a build, if only to have a plethora of brass and ammo options. Now IF the industry makes ready made rifles in 8 twist, AND offers AFFORDABLE brass/ammo, then I might bite. I see this as a niche round, although a good one. I would venture a factory 22-250 or even 243 will do in alot of varmints. My last few yotes were dumped w/a 6BR lobbing an amax at 2850, one a head shot at near 200 yds, taking about half its face off, it was facing me. It was a Ruger #1, that shot a sub half inch group at 330 yds, but no doubt, not a rifle for doubles It did dump my furthest deer kill at 400 yds. Speed is nice, but not always essential to success if you know where to hold or click. I would rather see the factories adopt a 6CM if only to give a fast twist option for heavy bullet shooters. Confident if Saami'd it would be set up in 8 twist rifles.
Nice thing about this 22CM.... it takes no fire forming. Just neck down, trim, load and fire! All the other rounds are ok, but I wanted something different and effective. This is what we came up with. Most of the credit goes to George and Josh Lapin, but I gave my requirements and this was the brain child.
I had thought that a 22 CM would be cool. We machined a 1-8" twist 22" 22-250 barrel for my DTA. I'm getting as fast as 3300 out of an 80 grain SMK at about 1/4 MOA at 100. It is crazy fun out to 1000 yards. However, I am not expecting much in the way of barrel life.
Having said all of that, I wish you would have come up with this 6 months earlier. Mine would definitely be a 22 CM. I will be looking back here for updates, and really appreciate you sharing this.
Is there something about the 6 Creedmoor's case design that makes it better for a .224 application than, say, 6.5x47?
Case capacity is a given...but is there also a brass prep component the Lapua requires the Creed does not?
