I finally got up the courage to shoot my Heym 600 NE. It only weighs 13 pounds and I was surprised that the recoil is not worse. I would say it has about 25% more felt recoil than the 585 nyati. In particular, it has more muzzle rise and more recoil velocity. However, the recoil of the 600 NE does not hurt and it is not frightening. But it does move my body quite a bit. This is probably not a caliber for use with a scope.

In contrast, the recoil of the 500 NE moves my body very little, but it is very fast and sharp - kind of like getting bopped in the shoulder with a 3 pound hammer, and it produces quite a bit of head snap. The 600 does not produce much head snap.

It would be really nice to see some photos of your rifle, particularly the bolt and magazine area.

I found the recoil of the 600 much more barible than the Nyati, which to me was grusome...the 600 will certainly "push" you around, but it is more push than snap...snap I dislike, when my teeth pop I know its not for me.

Did you buy the one on Gunbroker a while back? I was getting ready to go down to Florida to pick that one up in person but it was sold before I had the chance to do that. It would cool to see some close up pictures of it, especially the CRF action. Thanks.

500,

did you opt for this over the .600 OK ??

and what is the bolt diamter of this Heym Rifle ??

I wonder if the Montana PH can be set up for the .600 Nitro ??

Nitroman, I need to get going with a digital camera, but I am not there yet. Interestingly, the rails have a reverse step in them. So from top view, the rails are wider at the rear of the action than at the front. When the case rim gets pushed to the step, up comes the rim under the extractor and the bolt then closes.

Ray, I wonder if the Nyati you shot was too light or if it was loaded excessively hot. At 13.25 pounds, my nyati is not painful to shoot. By the way, it wear a piece of $100 Turkish that you sold to me.

Ming, yes it came out of Florida. I took a flyer on this one and it worked out. Life doesn't always go that way, but I got lucky. Before making the purchase I checked into the price of a new one and figured that half of that was pretty safe territory.

PC, I will still built a 600 OK. But this rifle lets me have some fun while I figure out how to approach the 600 OK. I will check bolt diameter and let you know. But I did notice that the bolt lugs go all the way to the front of the bolt face so there is plenty of meat on the side opposite the extractor.

500 what velocity are you pushing the 900's?

Karl

I found 900 gr bullets at 1950fps (600 NE) performance levels to be no trouble at all. Much less punishing in fact than my NYATI. 900's at 2250fps are getting there. I fully expect 2500fps will be easily achievable with Horneber brass.-Rob

Karl, I did not use the chrono but the load I used is supposed to give 1950 fps.

Rob, at 13 pounds, this rifle is as light as I would want a 600 NE (no brake). How much do your 600 OK's weigh?

500 - So, I take it your recoil comparison is that of a .600 with no brake and your other rifles, with? They also weigh a bit more, do they not?

Thanks Dan for the info. You were one step ahead of me on that rifle. NECG quoted me $12,500 on that rifle so it was one heck of a bargain for that puppy. Anyhow, it should be one of the coolest rifles in town. Have fun with it.

Thanks 500,

When/if I get my Montana PH actions I think I would like to jump to the next power level above the .585 Nyati. Just wondering the best way to go about it. Or I will build a second .585 but this time with no break and in all African trim (I am not sure yet).

PC,

The bolt is 0.750" diameter, but the left lug is has meat at the front so the bolt measures 0.8250 at that point to handle the large rim.

If you are putting together a custom rifle, the 600 OK will be easier to do, although it is not a factory cartridge. Also, I do not know if the MRC action will leave lug meat at the bolt face. I don't think they know yet either since they have not finished the design work but have only put together the rough specifications.

Won't the PH action also fit the 577 Tyrannosaur?
I'd go with the 600OK on the 550 action.

"Keep in mind that is bathroom scale weight, and all bathroom scales tend to give false high readings."

PS: 500grains, does your 600 Nitro have the parkerized barrel or blued? The one I saw in Anchorage was parkerized.

500 grs- What does the front of the chamber look like on the Heym. Is it slightly recessed for the .600 rim or flat and I assume the barrel is relieved for the extractor. I assume the extractor funtions Mauser like and the bolt turns without the extractor moving.Can you take some pics of the boltface /extractor and chamber area? A rimmed case in a bolt action is always an interesting proposition.-Rob

500 - Did you happen to see the article on the Heym .600 I posted a few weeks back? It looks very much as you describe. I can send it to you if you wish.

Nick, yes it is the same rifle model and I printed the article but I would love to have an email of it for archive purposes. Thanks.
