.585 Nyati Login/Join

I'm currently building a .585 Nyati on a CZ 550 Magnum action. That receiver is set-up for .416 Rigby. Relieving the rails won't be a problem but I do have a question on the bolt face. Do most of you guys rebate the rims to Rigby diameter or do you open the bolt to 0.640? The latter seems possible but the walls will get awful thin on a 0.700". Any recommendations would be appreciated.

BTW, the reamer is by Pacific and is correctly ground in the neck for Bertram brass. Dies are by CH-4D, while the barrel is a McGowan.

Thanks,

Lee Martin

that same action and bolt are used on the gibbs case, and if you can do it without a rebate, you'll be miles ahead

bertram brass is soft, and you can't hit 2300 with it

I really suggest you Lay down and wait for this idea to go away! Been there and done that. You'll regret it! I have a working 585 Nyati and unless you have Horneber brass and a throat reamer you are not going to be a happy camper. I speak from experience not BS.-Rob

Bertram brass is crap and will stick badly in any chamber. Find some of the Horneber stuff and still expect to neck turn.

Out of curiosity, if you own a complete rifle appropriately built for the .585 Nyati. How hard is it to find the components on regular bases. Or do you have to horde them when available.
If you have the do it once attitude, what route would you go for components:"Dies,brass,bullets, etc..."

For the 685 Nyati there are so many variations out there it's hard To say what works without a chamber cast of your rifle. I've personally fixed at least A dozen of them and seen twice that many I would not touch. While it can be made to work it's probably the most difficult big bore in existence as so many gunsmiths tried and failed. Does are not an issue but brass definitely is. It all depends on what chamber dimensions you have. Horneber brass is the holy grail of Nyati owners.finding any is a problem. Bertram is crap and to be avoided. If you own a Nyati, my honest suggestion is call Wayne at AHR and have him rebarrel to a .600 overkill. You'll be glad you did! -Rob
