CZ 527 magazine

[Wiz240]

Hi,

I am looking for a magazine for my CZ527 .17rem. I can't find any for sale in the UK.
Would anybody know if the .204 ruger magazine would work with the .17rem round? Rifle Mags.co.uk has the .204 ruger magazine for sale. ://riflemags.co.uk/cz-527-5-round-magazine-204-ruger/
I have tried a .222 & .223 magazine's but it loads the first but the second gets stuck in the magazine.

Thanks

Are you handloading? The 223 magazines should work. I use them for 204 Ruger. ~Muir

As It’s a single stack magazine, it’s vital to get the proper one (£76 .. and in stock at BROWNELLS.CO.UK ).

All the CZ527 magazines are calibre specific.

I'll need to stop using 7.62x39 magazines in my 6.5 Grendel then. I guess they only appear to work fine. Oh hell! The 300 AAC will need to give up the 223 mags as well!! Nutz! ~Muir

Ha-ha .. point taken on the offbeat cals.
The 7.62x39 uses a special size magazine & Edgar Bros UK doesn’t list the CZ527 in .300 AAC at all, but I’m sure you’re right.
Maybe I should have qualified the link with the words “case size” or “standard calibres”?

CZ will proudly ($$) tell you that you DO need specific magazines but the ones I mentioned interchange without notice. My Grendel came with one magazine but I had seven of the 7.62x39 mags so I never did order another: It was actually an incentive to buy the Grendel! I throw them all into one pack and use them interchangeably. I have used 223 mags on my 204 Varmint without a hitch. It would surprise me if I tried to use a .223 mag with 17 Rem and it wouldn't work. The OAL is shorter on the 17 Remington by about .1 inches. That's why I asked the OP if he was handloading.~Muir

(Yes. I shoot the off beat cartridges)

Hi,

Yes I am home loading, but it's the shoulder that gets stuck in the magazine.

Hi,

Yes seen them but "in stock" with a 5-8 weeks special order.
And after reading a recent post on SD regarding their ETA doesn't fill me with confidence.

Hi

I bought the .223 mag and I sent it back, I have been given 2 x .222 mags and the same thing happens.

I have cut/grinded one of the .222 mags to get rid of the indents..... it did improve, but 1/3 I still get a stuck case .

The reloading manual I have; shows the .204 ruger to have a longer point of start to the shoulder and a wider shoulder, that is what I was trying to find out.

Maybe I'll have to try and see.

Thanks

I guess I'm so used to running 17 Rem from a standard welled magazine I didn't think that the case might be too wide at the shoulder for a single stack. I was thinking OAL was the hang up.~Muir

Huw,
Still pondering on this. Yes, on taking a closer look at the Brownells UK website, it says that CZ527 mags are out of stock so have to be ordered in from HQ in the U.S. I tried to work out what the physical differences are between mags in the various calibres, but the images shown on this site all seem to be of the same article. No help at all & a waste of time looking.

Without any pictures to go on this is surmise on my part, but I think that the .204 Ruger magazine will have extended retaining lips for the longer body of the .204 case. If that’s so perhaps .17 Rem rounds won’t be released properly so might jam on the feed ramp. Muir can say whether that’s a possibility. He says that his CZ in .204 feeds fine with a CZ .223 magazine, but it would be useful to know too whether the CZ .223 feeds with the .204 magazine.

I’m puzzled. The .17 Rem and .223 case are the same diameter, and have the same length base to shoulder. There seems to be no reason at all why a .223 mag won’t feed the .17 Rem.
There’s a shallow cut-out in the nose of the .223 mag which the top round will clear, even if it’s too long for the magazine. If the rounds below are also over-length then each of them will bind at the front under tension from the spring follower. Your OP says that the second round won’t feed in .222 or .223 mags. Like Muir I'm thinking that reducing the OAL of your rounds might make this problem go away.

Hi Guys,

I'll try the .223 magazine again. This time I will reduce the OAL of the round.
Looking this morning in the Hornady manual the OAL is at set at the SAAMI max.
I am new to this reloading and only loaded some 400 rounds, 50 of them I had to disassemble as I sold the gun. So I do tend to go with the books that I have recommendations.

Thanks

Try Steve Kershaw, he's built a good few 20 vartarg and 221 fireballs on the 527 . I believe it's the same magazine . His contact details are on his Web page.

Thanks I’ll keep that in mind. I have order a .204 & .223 magazine to try, hopefully they will turn up tomorrow or the day after.

Apologies to both of you for not replying sooner, I have no excuses.

No I have not been able to find a solution yet but I haven't pulled my finger out and tried what Foxy Tales suggested to contact Steve Kershaw.

I did try the .204 & .223 magazine's, I also bought a used .17rem magazine off someone here on SD. All three of them were to long to fit in the magazine well .

I can only assume that the original action was a .222 as I have two .222 magazines here and both fit. The other possibility did CZ change something during the years of production.

Foxy Tales , hey you coming on to me ?
Not sure where I saw it , but I think the difference is at the lips of the magazine , sure Steve will put you right .
Good luck

The .222 and .22 hornet bottom metal is slightly different so if you’re rifle is built on a .223 the .223 and .204 mags won’t fit

For Sale: - CZ fireball mags

These came with a fireball barrel I bought a few years ago. They have been very well modified to suit a Fireball cartridge. BUT they didn't fit my 527. Pics with fireball cartridge shown and dinensions. £25 the pair posted.
