I want a new hotrod - 22creedmoor

[wboggs]

Got one in the works, Zack is making one for me and my brother. Why not

Keep us informed how things go. Most of us are interested in hot rods but don't shoot them. They are an interesting form of pushing the outer boundaries.

Ought to perfect match for 90gr bullets- get the true BC from them.!!!

Or just plain awesome with 40gr bullets!!!

Could you imagine 40 grainers, probably wouldnt make it 50 yards before turning to comet dust. Three of us are building them, should have them by fall.

Back in topic a bit. I didn’t build a 22 creed but I did build a 22x47, the Creed is certainly on easier choice though.

So if a 22-6mm Improved is a "true hotrod" would that make a 22-6.5 PRC a super duper manbun hotrod since you appear to have your hate on for the Creedmoor's and what about a 22 SAUM, would that be a super super duper hotrod? Do you have your hate on for the SAUM's too and if so what 4th grade name would you call one of those?

I've never understood the hate some have for anything Creedmoor. Adult men calling the different caliber Creedmoor's silly names because they're butthurt a Creedmoor gets more attention then their favorite cartridge just exposes ones immaturity and is childish. If you're a 22-6mm Improved fan, cool, good for you but you don't have to hate on one to like what you have. Never shot the improved version but I've probably shot just about as many coyotes with a 22-6mm and 75gr Berger VLD's as anything else I have and for what it's worth they aren't perfect either. Rem 6mm brass is mediocre at best and that's if you can find any as well as they make for a long OAL cartridge and work best in either a medium or long action. My dad had one built in the mid 90's on a SA Rem 700. The OAL with those 75gr VLD's was to long for the standard mag box so it was a single shot until I put a Wyatt's extended mag box in it and turned it back in to a repeater. It shoots good and runs those 75's along at 3600 from a 24in tube but a 22 Creedmoor would do the same and have, much, better brass that is readily available not to mention a more workable COAL in just about any short action rifle.

Well said.

 

[butchlambert]

Well, I had a 22-284 improved. My first hot rod was a 17-220 Swift improved. I've outgrown that BS!

Have a 22CR barrel in the works now. If I can get a 62gr up to about 3650 then thats all I require of the cartridge.
Using a 22BR right now, but need just a tiny bit more HP

 

[Mark W]

Well said.

I’ll never own anything with Creedmoor on the head stamp and I can assure you that it has nothing to do with being butthurt. It has a lot to do with the people who think it’s the greatest thing since rice, bread, and sunshine, when in reality it’s an ok cartridge that’s not really any better than the many that came before it.

I also don’t buy into the highest BC for everything, especially varmint rifles. I set mine up for MPBR. I’m not that good at judging range and there’s not always time to use a rangefinder, so I don’t want to lob my bullets out there.

I think the 35gr Hammers were made for the 22PRC

I'm no Creedmoor fanboy. Quite the contrary, but brass is available, and that's a thing right now, so I could understand going to it.

I was mostly agreeing with the comment about the guy sounding like a 4th grader.

Reloder 26 for the win....again

 

[Bodhisafa]

what is the idea behind the 22 PRC?

If a 22 creedmoor can max out the potential of most, if not all, cup and core bullets. You’d be just adding more powder for no gains? Or is it to drive solid bullets at even faster speeds?

Just continuing the conversation here ( for education)

Please explain what you mean by maxing out cup and core bullets potential. My medicine of choice for a fast 22 is a 22-243ai. It will push bullets faster than a 22 creedmoor by a fair margin and I’ve not experienced anything that would tell me that any bullets potential was maxed out.

I have a customer already hit that number no problem.

That’s why I mentioned “If”.

Looking at bullet rpm/speed/the chance of dematerialization. How fast can these bullets go before physics wins?

I guess it’s possible to choose the wrong twist and then push the wrong bullet too fast and have issues.

Personally I would never choose a twist faster than 1:9 or a bullet heavier than 75 Grains for any fast 22 build. If someone insists on a fast twist and heavy bullet, they very well may be limited to velocities that can be reached by a 22 creedmoor, but it doesn’t have to be that way.

 

[Idaho-Lefty]

I am classified as old by any definition and completely agree with you on "easy". I am in the process of switching to the 6.5 creedmoor for 90% of my rifle shooting.
Also, less recoil is up on the list after easy.

Try some 130 grain, ELD-M's, in your 6.5 Creed,. for freakin' Awesome, Accuracy and LOW Recoil, in a BRAKED, 6.5 !
In my 8.5 pound, "Walking Varmint" BRAKED, Rem 700, in .22-250, the 50 grain, V-Maxes @ 3,500 FPS,..
"Blow up" chit and,.. Sage Rat, body parts, CAN be, SEEN,.. in the Scope !
Me,.. a very HAPPY, Camper with this,.. slower, lighter Bullet, Load !!
Heavy Bullets,.. ARE Fine for,.. Grizzlies !

I'm really grateful for this thread. I've been day dreaming about being able to reach out further with a 22 cal for quite a while now. I've read up on stuff like the 22-250 AI, 22XC, 22BR, 22BRA, 22ARC/Grendel, and now the 22CM. Seems like the bigger stuff (22-250 and up) do really well with +75gr bullets, and I can certainly understand where that would be a significant advantage when shooting longer distances. However, I'm really surprised at how little advantage they offer with the midweight stuff like the 62gr eld in comparison to stuff like the 22BR and 22ARC. Hdy's 22arc load data for a 24" bolt gun puts the 62gr eld at 3550, and it sounds like the 22CM gets you another 100 fps or so. That's a big change in case volume (34.2gr H20 vs 51.5 => 50% increase) for a measly 100fps. I suspect you can get a little more than 3650 from the 22CM, but its still eye opening to see how much more volume is needed to get a slight bump in MV in that weight class. Its basically convinced me that if I'm not willing to spend a lot more $$ for the heavy bullets (and more powder to push them), there's really not much of an advantage with having such a big case.

I think after you get about so far overbore on about any caliber the gains in velocity to the amount of powder used ratio starts becoming a point of diminishing returns. We can keep going bigger case capacity and stuffing more powder behind a bullet but after you get past a certain point the gains in velocity for the amount of powder used tend to be less and less.

Like Mark W my choice for a fast twist 22cal to shoot heavier bullets is also a 22-243 Imp. except mine has a Krieger 28in 8tw and I'm shooting the 80gr ELD-M 3650 w/RL26 and I would say it's definitely an upper end load. IMO, the case capacity of the 22-243 imp is right there at that point of diminishing returns. Will a larger case with more capacity like a 22-284, 22 PRC or 22 SAUM sling the same bullet faster, absolutely, but is the amount of gain you get for the amount of powder used to get there reasonable or worth it, for some it is but for me it would not.

I could care less what the name on the case head says. I'm far more concerned by does it have really good brass quality and is that brass easy to get on a regular basis. I've always been a big fan of the 22-250 and I have numerous different rifles with AI'd or Improved chambers but right now a 22-250 would be a hard one to recommend, unless you plan to shoot factory ammo, because brass has become very difficult to find and with top quality Creedmoor brass still pretty easy to get it's no surprise the 22 CM has become as popular as it has not to mention you get a little boost in velocity with a 22CM over a straight 22-250 due to it having a bit more case capacity. You can certainly go to a 22-250 Improved and that pretty much evens them up but that doesn't fix your 22-250 brass availability problem. That 22-6mm I mentioned in an earlier post has a 9tw Lilja that is nearing the end of its life and when the time comes to rebarrel it there's a very good chance it'll come back as a 22 or maybe even another 6mm CM. Certainly not because I think saying Creedmoor on the case head means anything special but because Lapua, ADG, or Alpha brass is not only good stuff but it's easy to get and it'll match or exceed the performance of any of the others I would consider. Heck, even if the velocity was slightly less I could still live with it due to the easy button being so accessible.

I love the 22 Creedmoor.. I have a custom one in a 7 Twist on a Mack Brothers action shooting 85.5gr Bergers and it shoots lights out. Was holding .25-.27MOA for the first 400ish rds. Now the throat eroded some .116” and it’s holding .5 MOA all day. I sat some out to .015 off the lands yesterday and it went back to shooting .25.-.27 MOA groups. I only have about .120 of bearing surface in the case now though, so that’s it, I’ll shoot this until it opens up close to 1 MOA or I decide to get a new barrel.

This has been my first 22 CM experience and I’d definitely do it again.

just gotta Get the whole gas mileage (barrel life) out of your head and enjoy the ride!
