What about the 22Br Norma ?

 

[sir-slots-alot]

People miss the point of 22CM, it's about being able to use the cartridge in AICS (or even AW) magazines, have access to small rifle primer brass and being more suited to long, heavy bullets due to the short case.

But that wasn't the question posed. His question specifically asked for 53 /55 grain bullets.

If we want to discuss longer bullets in the 22.250 - i have had a 22 BR and two 22.250 rifles specifically built for shooting 75 / 77 grn pills and fired thousands of rounds. Each of the 22.250s sent a 75gr bullet at over 3300fps with devastating LR accuracy.

Personally if i was going to do it again i would stick with the 22.250 for cost and easiness or go back to a 22br with a tight twist for greatly increased barrel life and accuracy potential . The 22 CM is just another 22cal with a tight twist - it might be re-packaged and re-badged with a few go faster stripes - but its actually a case of putting new strings on a very old guitar

As mentioned previously, where the 22CM outshines the 22.250 fast twist, is in feeding from an AICS mag. The 22-250 will feed from an AICS mag...sort of, but not as smoothly as the more straight tapered 22CM case body. Because of the steeper body angle, 22-250 can get a little buggered up in an AICS/AW mag...

I suggest taking a look at the venerable .243 Winchester. It may not be very fashionable but with handloads its performance is blistering. You have the option of light bullets e.g. 58gr that are getting towards 4000fps and yet you can also shoot heavier bullets at about 3000fps even in traditional 1 in 10 twist, e.g., 90gr Sierra FMJ bullets work well in my elderly Tikka M55 at long range of 1100yds or so.

Couldn't agree more! My 1st centrefire rifle was a 222 and my 2nd a 243, both M55s. Over the decades in pursuit of foxes I shot several calibres including 22 Swift and 22-250AI. I still have the same 243 as it was the best of the lot. IMHO of course.

52/53gr bullets..22CM or 22PPC ...fast and very accurate with factory sako 52gr ammunition ...

Just tried some 22-250 in an AICS magazine it really doesn’t like the tapered case.

I can certainly see the merits of the 22CM for use in custom rifles. If you are spending the money on a custom barrel the ease of forming 22CM brass from 6CM brass in a single pass from bushing dies and available 6CM brass gives an easy advantage over 22-250 in terms of velocity and feeding. What’s not to like. Other than barrel life but in hunting terms that’s a lot of foxes.

IIRC, you have to open up the forward part of the feed lips to account for the case taper. Even then, it's not optimal.

1-7.75 twist 22-250 owner here

Factory sako 55gr going 3550fps

Home brew yew tree tlrs using n140 almost identical velocity

Rs60 with yew tree is 3750fps ,only fired 10 rds at this pace

I'm not sure I'd not have been better off with a 243 but I absolutely love my rifle.

What about 22-250 AI ?

There is the extra step of fireforming the brass. At least with 22CM you can just run 6CM brass through a die and brass is formed.

I have never used 22-250AI but the anecdotal information I’ve had is the shoulder is sharper and doesn’t feed as well as a shallower shoulder.

keep it matey 22-250 is awsome calibre

 

[Dave_45]

keep it matey 22-250 is awsome calibre

I plan too mate , I'll rebarrel it to the same when it goes , but with a lighter profile barrel.

Was more thinking along the lines of straight walled would feed better, I don’t think the shoulder is an issue, certainly isn’t on my .223 AI or K-hornet.

Although I do agree on the simple neck down being more straight forward fire forming isn’t usually an issue and for the 3 case I fire form the forming load is plenty accurate enough for use.

With the advent of the 22 Creedmoor, I have no idea why anyone would mess with a 22-250AI. The only real difference is one has a 30* shoulder, and the other has a 40* shoulder (respectively). And as mentioned, that 40* shoulder can cause a headache for feeding; especially if the feed ramp is short or steep.

As to other AI'ed cartridges, people should be careful when comparing all "AI'ed" cartridges, as some have a 30* shoulder, and others have a 40*. So, it's not always and apples to apples comparison.

JMTCW...

Appreciate that, I was comparing to the 40* .223 though…..

Brass cost and availability would be one factor, though I appreciate 22 CM could be just as easily formed from 22-250 brass.

I’ll have a foxing rifle a slot coming free soon. Could be either of the above!

I run a 22-250 1:8 twist shooting 75/77gr tipped bullets at 3450fps from a 26" tube for thermal foxing. The results are devastating and is pretty much flat to 300 yards with a 230 yard zero. It runs perfectly in a 5 round AICS mag with 5 rounds in it, however fails massively in a 10 or 12 round aics mag.

Yep, that body angle adds up as you stack rounds...

 

[C h r i s]

Back to the original question - anyone shooting 53gn bullets from a .22 Creedmoor? I guess not - any .22 Creedmoor owners on here?

This question isn’t really about twist or cartridge availability, its about how a relativly short bullet shoots from a rifle with a potentially long freebore, cut for 75/77/80gn ELD bullets.

 

[Envillegc1]

240 Wetherby anyone?
