If you could choose: Brno Z, ZG 47, ZKK or Cz 550??

[50lawman]

I have a CZ 550 Rigby in 416. I took a 42 inch Cape Buffalo in Zimbabwe. I like the availability of having an extra round. It is solid and well built. IMHO.

One caveat on the CZ 550 Rigby is a set trigger. If you push the trigger forward, for lack of a better term, it becomes a hair trigger, meaning any slight touch, tug or whisper and the round touches off. My curiosity got the better of me one day at the range lucky for me I had the rifle secured in a lead sled. Surprise or better yet effing surprised. Never messed with that setting again. Couldn’t fathom the reason to have this setting. Has anyone else with CZ 550 416 Rigby experienced that trigger setting?

ZG 49 Sn

The ZG 49 Sn and the related ZG 51 Sn[1][2] are Czech prototype sniper rifles. The ZG 49 Sn was the brainchild of Czech designer Otakar Galaš (1904 – 1968, aged 63/64) who decided to develop his own specialized sniper rifle in 1949; this design would end up becoming the ZG 49 Sn, which used a...

It is the standard trigger on the last of the CZ 550 models. That hair trigger can be adjusted from ounces to a bit over 1 pound I believe. I have mine set at about 1pound which gives me more “breathing” room. I find it helpful for sighting in but very rarely use it in the field.

Agreed

I think its a great trigger but lots seem not to like it and want to toss it for something else.

Thanks for the info, glad to see that there are adjustments for it if needed.

You can deactivate the set trigger feature quite simply. But thorough testing of the trigger function is advised after that. I did that on my standard 550 in 300wm . Instructions were in the CZ US catalogue 10 years ago.

Same, 3 pos M70 safety and straightened and filled bolt (AHR #1 CZ upgrade). If the OP was looking at a heavier caliber (450 Rigby, 500 Jeffery) I would say CZ 500 with the CZ #1 upgrade hands down. I think it's too big and heavy for smaller calibers.

 

[Spongebob]

Very much dependant on caliber and application, having a few of these variants strangely enough my go to rifles in for any hunt are selected in this order: CZ550 in 375 / ZG47 in 9.3 x 62 and ZKK602 300WM.

The set trigger on the 550 is a bit hairy but I find that in thick bushveld conditions, I tend to forget setting the trigger. I can be set and deactivated.

That's what I did. It's an amazing trigger set to 2 3/4 lbs on my 500 Jeffery.

Hi,

In spite of the ZG47 is a better finished rifle, for the 9,3x62 I chose a ZKK 600, very scarse but I have one, or the CZ 550. That because as a handloader (the 9,3x62 is, in my opinion, a cartridge begging to be handloaded...) those ZKK and/or CZ550 standard has a 5 round magazine and are longer as well.
And the ZKK 602 in 300 Win Mag is, also in my opinion, really a monster in weight and lenght totally unnecessary for the 300 Win Mag!
Having said this, I love the ZG47! I miss one in 7x57 with a period 3x Meopta scope with te original mount...

Yes, there is a difference between a standard Mauser magazine and a Mauser 9.3x62 magazine. The floor plate on the latter is wider. Easy to see when you put them side by side.

It’s not significant though.

 

[ZG47]

It’s not significant though.

The difference, with all due respect, will be significant, when the percentage differences in diameter of base and shoulder from say, the 8.2x57 IS, 30-06 and 8x64 S to: the 9.3x62 are adequately compensated for by the additional magazine width of a 1930s Mauser factory sporter chambered for the latter cartridge.
I started to truly appreciate the value of percentages in decision making when I came across the coefficient of variation. Years ago, Handloader Magazine published a reloading article about the 8.2x57 IS, using the inappropriate SAAMI nomenclature ‘8mm Mauser’, if I recall correctly. My copy has been packed away for an impending house move. In the aforementioned Handloader article, the term ‘coefficient of variation’ was used. I pondered for a moment and realised that, in analysis of a statistical series, it had to be: the standard deviation divided by the average. I started calculating coefficients of variation for my recorded shot strings and achieved greater clarity when interpreting my data. Less time pondering, fewer headaches and … I got in less trouble for ignoring/delaying routine tasks at home!

Hi,

Here is a little gem: a table, original from the then Mauser-Werke, published in the GREAT and definitive

Jon Speed's book "Mauser - Original Oberndorf Sporting Rifles"​

with the correct magazine dimentions for almost all the cartridges Mauser Sporting Rifles were made for.

 

[ZG47]

Thank you. I have downloaded it.

 

[Themauserkid]

All that said I have an original 8x68 Schüler with a standard width floorplate, though admittedly the magazine well is blown out about as big as you could go without welding one together.

 

[colorado]

It’s not significant though.

Another important dimension is the indentation in the magazine follower. My gunsmith, Kevin Weaver, identified it as an issue in my CZ in 500 Jeffery, and it was the last thing that needed work on to have it feed and function flawlessly.

Yes, more than one way to get the desired result. Hong Tse, a departed acquaintance of mine and a leading member of the New Zealand Deerstalkers’ Association, was a devotee of the 7x61 S&H. At one stage, Hong imported specially shaped aluminium magazine wells from Holland & Holland and sold them to other hunters here in NZ who wanted to convert standard Mauser actions to various belted magnum chamberings.
How about showing us some images of your rifle?
