I read conflicting reports concerning the CZ Safari 550 holding five or six down. CZ web site states five. Which is it? Also, can they hold five down if rechambered to 375 Wby? If no one here has one in 375 Wby could someone who also owns a 300 or 340 Wby see how many rounds will fit in the 550's magazine? Thanks! My biggest fear is when I die my wife will sell my guns for what I told her they cost. | ||

I believe the variation is due more to the stock than the rifle itself. I have two stocks for my CZ 375 H&H, both "American" versions. One stock only allows 5 in the magazine plus one in the chamber. The other allows 6 in the magazine and one in the chamber without issues. It's the same action being used for both stocks, hence why I believe it is the stock. My theory (and it's entirely that) is that one of the stocks does not allow the magazine box to be fully snuggled into the action and floor plate. That little bit of gap allows the sixth round to be chambered. The stock that holds only 5 almost fits the sixth round. ____________________________ If you died tomorrow, what would you have done today ... 2018 Zimbabwe - Tuskless w/ Nengasha Safaris 2011 Mozambique - Buffalo w/ Mashambanzou Safaris | |||

Sevens, Interesting to hear that. The magazine on my CZ .416 Rigby sits proud of the stock and when I can find some ammo for it, will be interested to see how many it holds. | |||

Very Good Sevens ! If your CZ 375 holds six in the mag, open the floor-plate and see the gap between the bottom metal, mag box, and action. These stocks are not in-letted correctly. Watch that gap, your follower can get hung up in it. If all the metal is fitting tight, you should only be able to hold five down. The sixth will almost go in. | |||

Mine holds 5+1. -eric " . . . a gun is better worn and with bloom off---So is a saddle---People too by God." -EH | |||

I just checked mine. Five down and one in the chamber. Quite a comforting thing, isn't it? Rich DRSS | |||

And for the second part of the question: The .375 H&H CZ box holds 5 also in .375 WBY: 5 down in the box. Mine feeds well. It has been slicked up merely by polishing the insides/feed surfaces, and has been properly bedded in glass/epoxy with pillars and crossbolts. You can also load to 3.75" COL instead of 3.6" using that CZ box. That is an advantage with long monometal bullets such as the TSX or Walterhog. Saeed uses his .375/404 Jeffery in a Dakota 76 with .416 Rigby length box. Same principle for use with Walterhog bullets being very long in the nose. Of course a CZ 550 Magnum would be perfect for the .375/404 Jeffery also. I have one in .375 RUM, Remington's rebated imitation of Saeed's cartridge. You can jamb 5 of the .375 RUMs into the box if you push hard, but it is too tight. Should limit the CZ box to 4-down with .375 RUM, 5-down with .375 WBY. | |||

There are ribbed boxes and non-ribbed boxes for the CZ 550 Magnum. Ribbed ones have indentations vertically on the sides, stamped into the sheet metal, to decrease the effective box width fore and aft, two ribs on each side of the box. That is sort of the opposite of windowing a Winchester M70 box for .375 H&H to make it fit .375 RUM. CZ uses the same sheet metal box, ribbed or non-ribbed, for .375 H&H, 404 Jeffery, 505 Gibbs, etc. My opinion is that the CZ internal box non-ribbed dimensions are most perfect for 404 Jeffery. All the rest are "make-doo." Using a ribbed versus non-ribbed magazine box with the .375 H&H can also result in 5-down with ribbed, and 6-down with non-ribbed box. Also could result in feeding issues, eh? What say "All y'all?" | |||

Just want to make sure, have you actually tried putting 5 of the 375 Wby rounds in the mag? Any feeding issues with the rechamber? Have a lead on a 550 Safari in 375 H&H and if I buy it it will most likely be a candiate for the Wby rechamber. Used to own a 375 Wby built on a Dakota 76 and four down was such a tight fit that it wasnt useable. The idea of five down has my attention. My biggest fear is when I die my wife will sell my guns for what I told her they cost. | |||

My CZ held 6 down in the mag. I would think 5 down for the 375 weatherby should be easy | |||

I'm curious, for all those that have the CZ's. Does the floor plate fit flush on your rifle or is it sunk into the stock a little? ____________________________ If you died tomorrow, what would you have done today ... 2018 Zimbabwe - Tuskless w/ Nengasha Safaris 2011 Mozambique - Buffalo w/ Mashambanzou Safaris | |||

Randy, Like I said above: "The .375 H&H CZ box holds 5 also in .375 WBY: 5 down in the box. Mine feeds well."" I refuse to make a shootaway-style video showing me loading 5 of the cartridges into my CZ 550 Magnum .375 Wby, and then rapidly feeding and ejecting the 5 cartridges, with a clock ticking seconds off beside the rifle and today's newspaper headline and date visible in the frame. I could easily do that, but I refuse.  Note also that the CZ 550 Magnum 404 Jeffery holds 5 down in the box, and it also feeds and ejects slick as greased owl poop. | |||

The old hogback, Euro Lux stock always seemed to be well fitted to the metal, at least no floorplates sunken below wood. The newer American-style-Phatboy frequently seem to suffer from sunken floorplate. My favorite CZ stock for the 550 Magnum is the Kevlar with full aluminum bedding block made by B&C and only available from CZ-USA in Kansas City. No sunken floorplates and no mag boxes standing proud with that one. Fits flush every time.  | |||

Thanks guys. Ordered the rifle and have plans on rechambering it to 375 Wby. KNEW I should of not sold the reloading dies when the Dakota found another home via gunbrokers. Being a lefty never owned a CZ big bore before but just love the idea of 5 down. Great confidence builder and this is coming from a guy who would rather hunt with a double rifle. Weird, eh  My biggest fear is when I die my wife will sell my guns for what I told her they cost. | |||

Would appreciate ideas for some quality QD rings for this rifle. Keep in mind this is a lefty CZ if that makes a difference. Thanks My biggest fear is when I die my wife will sell my guns for what I told her they cost. | |||

I have one pair of the Warne QD-Lever rings in low height. These are discontinued, not available anymore. You can use them only with a 2.5X Leupold compact or only another scope with such very small ocular bell. Any other scope requires the medium height or taller. Warne and Talley QD-Lever medium height rings are fine for most applications. If you replace the screws in the CZ-made rings with socket-head metric screws of automotive quality, they become QD with a hex/allen wrench from your pocket, but are a little higher than the medium Talley and Warne, and not as pretty, yet very functional, and less likely to snag levers on things .  IIRC, have pictures on a puter at home, and actual physical specimens of the above ... | |||
