Starting with a CZ 550 Magnum action, should you use the 375 H&H, and rebarrel, or, the 458 Win Mag, rechamber, etc.?

Thanks

the 375 will be the easist, as the case is 2.85, and the lott is 2.80. rebarrel (pcanor, shilen, douglas, etc) and have a ball. The 458 winnie might require more work and a new mag, it depends.
and not asked, if you take a 416 rigby, and rebarrel to 470 mbogo, you have a whooperstoomper

Much difference in case capacity between 416 and 375?
How about necking up the 416 to 458?

from quick load
416 rigby 127.5 gr water
375 HH 95.30 gr water
450 rigby (it's real) 133.01 gr water

and, check out www.470mbogo.com if you want to know about it out to 475. This one is giving me a constant desire to build a '75.
hope that helps.

ream out the 458. hornady sells basic mag brass for $24 for 50 pcs. I believe the 375 and 458 use the same action.

Just go to thegunsource.com and order a Ruger M77 magnum in .458 Lott. It will cost you about $1,200. I own one in .416 Rigby and in my opinion is a much nicer rifle.

I agree with Homebrew! Cost will be lower,in the long run, and the rifle is just as good as what you will get by building! I would figure to add about $200 to that $1200 for fine tuneing, and bedding! $1400 for a working 458Lott is cheap, IMO!

PS:
If you subscribe to African Hunter magazine, in the Chirimo issue, Volume 7, Number five,(KUDU on front cover) on page ten, you will find an add from "RIFLEMAN Alexander" they list CZ 550 LUX rifles as being factory chambered for 458 Lott, and in stock there! May be these are only shipped to Africa, but it would be worth checking the importer here to see if they are available in the USA!

I don't agree with those who say just go out and buy a gun. Where is the challenge in that? While I can't fault the Ruger M77 for the price, The ability to provide really custom features like slick quiet safeties, muzzel brakes, STOCKS THAT FIT YOU, RECOIL PADS THAT WORK etc. mean that custom is the way to go. Frankly, you can have an extremely nice 458 Lott or 450 Ackley built starting with a box stock CZ550 in .375 for not a whole lot more than just going out and buying a Ruger.
I have built two 450 Ackleys on pre-64 Win M-70's using Shilen barrels with barrel band front sights and quarter ribs. I shopped the gun shows till I found an action for $400 and a magnum stock for $100. The rest of the parts were less than $400 I did all the machine work including fitting a second recoil lug and the sights myself. This is the smoothest feeding/shooting DGR imaginable IMHO. It feeds and ejects like it was on ball bearings. The M70 safety is great as is the trigger. If you have an action, Pac-Nor will fit a barrel, chamber it etc for you and machine in a good functional muzzel brake for less than $400. They are emminently reliable and competent! If your at all handy you too can finish and fit a nice custom stock and have a rifle in which you can justifyably have a great deal of pride. Finally, consider talking to Ed Plummer at AHR, they really understand what it takes to make a CZ550 play and ED builds excellent customs in many calibers. You could easily get them to do all your metalwork and do the stock yourself.-Rob

The BRNO/Chay Zed actions are just not as smooth as some of the competition. I was reminded of this this afternoon when I ran the bolt on my .375 H&H BRNO M602 and snapped a shot, and then did the same with my Kimber M89 BGR -- also a .375 H&H.

You will need to add some cost for your gunsmith to smoothup the action, unless you can do it yourself like Rob described.

I handled a factory .450 Rigby built on a BRNO M602 action, talk about smooth taken to the ultimate. That rifle was 9,000 pounds sterling, marked down to US$9,000 as a show special at SCI a few years ago. This was before the Rigby marque was purchased and moved to the US.

Soc,
I rechambered a .458 Brno to the .450 Rigby about four years ago. With this round you get much lower pressures, the possibility of higher velocity (if you REALLY want it) but you pay the price in magazine capacity. All in all, it wasn't cheap. Nothing done the way you want will be. Good luck with the project. Just one word of advice, when you get it sighted in stop shooting off the bench. Your neck will appreciate it.

So much for the easy route:

HI
I've heard rumors that you make the safari in 458 Lott?
Is that true, and if so, how do you order one?

Thanks

The ruger looks good, but I like longer barrels.
HMMMMM.

Rob:
You mention a couple guys in the last part of your post.

Could you give me full company names, if you have em, and I'll look em up?

Thanks

OldSarge:
Where do you get brass?
It still uses a 458 bullet?
gs

The .450 Rigby indeed uses standard .458 bullets. The brass is an easy one step neck up from the .416 using a tapered enlarger ball from RCBS. After necking up, the case will need to be fireformed to square out the shoulders. I use 105 gr. of IMR 4350 for 2280 fps in a 26" barrel. That load knocks buffalo down. Really, it knocks them DOWN. Now that doesn't guarantee that they won't get back up again but if they do it's weak and wobbly. Awesome round!

Use the CZ in .458 Lott. They will often work with just a rechamber. You may also need to do minor work on the feed rails and ramp, but the same is true with the .375 H&H CZ. Even though the .458 round is shorter than the .375, the CZ550 in .458, or at least the one I owned, is build on EXACTLY the same action, including the EXACT same magazine box length. You can pick up a new CZ for around $600.00, and rechamber it for around $100.00, so you are into a Lott for around $700.

Call Ed Plummer at AHR at 1-800-716-4445 or Chris at Pac-Nor at 541-469-7330.-Rob
