I recieved my .585 Nyati cases from Horneber today. I ordered before some of the forum members joined in a larger order, but this should mean your�s is on their way too.
The cases are of outstanding quality, very uniform and ready to load. No need for forming as with the Bertram basics.
Regards// J.G

J.G how ere they for length ?? Did they need trimming ?? Also are they thiscker around the shoulder than the Bertram stuff. I mean are they stronger ?? I am looking forward to getting them my rifle is not that far from finished

PC,
The cases are exactly as long as my Bertram cases after forming and trimming in a trim die (70.9 mm)
The most important difference to Bertram cases are that Horneber�s cases are uniform in thickness (and stronger), primer pockets are centered and they are not "pre-bulged" like many of the Bertram cases I have struggled with.
I do not want to kick on Bertram, I have a lot of cases of their manufacture that are good and fully usable, but Horneber�s seems to have passed a tougher quality test. Regards // J.G

J.G,

thanks for that, I have around 120 Bertram cases for my coming .585 and I hope they will be of some service, so in general you have found the Bertram Brass to be useable or I suppose they have got you buy to this stage. I have been told that the Horneber brass will solve a lot of the problems the Nyatti has which is mainly due to what was once the only source of brass Bertram.

I have been using .416 Rigby Bertram Brass and am really not that impressed with it. Always get sticky extraction does not matter how much I reduce my powder. Does this happen with the Bertram .585 Nyatti Brass ?

PC,
The only time I have had such problems with Bertrams nyati brass was when I overestimated my recoil tolerance level and loaded too hot. Since then I have kept velocity around the old .577 NE formula, 2000-2100fps with 750grs bullets. // J.G

J.G,

I would be interested to know at what velocity wre you pushing your bullets in the .585 to get problems ?? I am wishing to use 650 gr woodleigh's in my .585 and am hoping to get 2400 fps as my working load for hunting without any extraction problems in either my Bertram brass or my horneber brass.

J.G I am also interested to find out what is the maximum velocity that has been obtained with the 650 gr projectile in the .585. I have heard & read a lot of data for the 750 but it seems that everyone ignores the 650 gr projectile in there .585's. I think this is a shame because it could be the more practical bullet weight to use. What do you think ??

What barrel length/ action is your .585 ??

Mine is on a 602 action, it has a 25" stainless barrel & 3" of muzzle break (which is detachable). It will have a fiberglass/kevlar stock in the weatherby style (I like weatherby stocks for recoil) is fitted with rem irons and also will be topped off with a leupold 2.5x compact in warne fixed mounts. I have had it made so it hold 3 rounds in the mag & one up the spout in a slightly staggered format. The action is finished in a matte black while the barrel is bead blasted. I am also fitting 2 mercury recoil reducers in the stock & possibly another in the forend. I am hoping for a loaded weight of around 12 pounds give or take.

I have written this as though I am doing the work, but I am paying a gunsmith to do it, I can't even build a sandcastle

PC,
I have no measured velocity for the 650 grs bullets, but 2400fps should not be a problem to achieve. Start with 135 grs RL 19 and climb slowly upwards.
My doubt would be if the bullet will hold together at that speed. I dunno.
Better, IMHO, would be the very fine 640grs FN Solids from GS Custom if you want lighter bullets and speed in the Nyati.
My rifle is built on a CZ 550 Magnum action and has a 23" Lothar Walter barrel wich is 1" at the muzzle. Laminated stock in classic style and a peep-sight. No mercury recoil reducer and no brake, 11.5 lbs unloaded.

Hey 585 Guys,
just wanted to remind you guys to rework your load data on the new brass. It's bound to be thicker, harder and better than the BB.

Thanks Jeffo,

Do you think we will have to reduce our loads or do you think we will be able to increase them

J.G

So you have a 23 inch barrel on your .585 NYATI I am sure that the .585 NYATI will make 2550 f/s with a 26-28 inch barrel with a 750 grainer. Have you used the 640 grain GS Custom FN solid bullets in your .585 NYATI??? What MAX velocity do you think is possible with them.???

Thanks...!

Hey, you guys in Europe;

Have any of you used Harold Wolfe's cases? A buddy of mine is having a .585 built and got 100 cases given to him by a friend in Belgium. You don't mention Wolfe so I was wondering if there is a reason?

Overkill,
Yes, I have used 640 grs from GS Custom. As for maximum speed, I have no idea.
When you say 2550fps is possible with a Nyati and 750grs I would say: shoot a 750grs bullet at 2100fps first and then ask yourself if 2550fps is what you want. I doubt it.
// J.G

Gator,
I�m sure Harold Wolfe�s stuff is good enough for anyone, but I have no contact info on him. That�s why.
// J.G

Yes I know about the recoil every time I shoot my .460 Wby from bench...

What velocity do you get with the 640 grain FN bullet??

Gator,

Harald Wolf uses brass from Horneber.
