Do you mean America Hunting Rifles (AHR) in Hamilton, Montana run by Ed Plummer?

Will your rifle have a single stack magazine? How many rounds will it hold down? What weight will it be? Will you use a muzzle brake?

Yes,this is ithe ones...Single stack,2 down(I will see about 3 down)I want it lighter,around 10-11pds,20"barrel and detachable brake for sighting in.Will be here in a few months,ready for "Hogzilla" down here in Hogridden Georgia!It will go to Alaska in May for my 2nd Brownie and Africa in July as a "light rifle" companion to my Ken Owens 4 bore double(2000gr@1500!)...

Dan,

That cartridge line-up, are those the .600OK, .500AHR, and a .500A2?

Bent, that sounds like a good guess but the website did not say. The left one is definitely a .600 OK. The 500 A2 (on right) will sharpen at the shoulder at bit when fired.

Safarikid,

What country/company are you hunting with?

Just got back from Botswanna in August,good hunt...but headed to Tanzania in July(3rd time)...Talking at present with Mark Sullivan,but not sure yet.Maybe TGT again?

Be a little cautious about ordering a 10-11 lb rifle in 600 OK with a 20 inch barrel. The muzzle blast and recoil at 2250-2300 fps could be a little intense. Ask some of the other 600 OK owners before you light off this cannon My rifle is at 14-15 lbs and has a 25 inch bbl.

Does the AHR OK rifle hold 2 rounds down?
and can you choose barrel lenght?

Use the 168 gr of IMR7828 load( once fired case and a drop tube) with a 900 gr woodleigh and you'll be right around a mv of 2100 fps or so. Thats about 150fps above the old .600NE. In a 10.5 lb gun it will be just fine. Consider using a Mcmillan express stock instead of wood. Maybe a 22 inch barrel with brake and leave out the mercury recoil reducers. I am building one with that recipe for the load described above as a more practical hunting gun. Remember you need a .600NE sizing die to resize once fired brass. You'll probably get a pass-through on most animals with that load and good bullets. The .600OK just flat works, no serious quirks and totally manageable with the proper loads. OF course you can inflict great pain on yourself if you want to.
By the way I heard Mark Sullivan lost his license to hunt in Tanz. If you do hunt with him make sure you don't leave your wallet lying around as ol Pano might be sneaking around at night.-Rob

Thanks for the reply and info....Do you have one?I am having it made with both a Fancy wood one and a glass stock.I feel that at 10pds with the high effiecient detachable brake,recoil wont be a major problem sighting in and then I will leave it off for hunting(they are so ugly anyway,but they do work!)I plan on shooting the Woodleigh Soft Pont and maybe Bridger Brass solids(they look like sledgehammers).Also,Granite Mountain action or CZ550,big differnce in cost,is it worth it??!!
Please give me a call as I would like to speak to you more on all this,or give me your number...Thanks,Tom 912 484 4700

How does it shoot and do you like it??

Do I have one? No , I have three .600OK's. I developed, designed and built the first one( I did all the metalwork and chambering and worked with AHR on the stocks. PM me and we can talk. DO not take the Muzzel brake off. Even with the load I described it will hurt big time. Plus, you will not be able to recover quickly enough with DG to get a fast second shot off. I designed that muzzel brake and it works really well. It may be ugly but it reduces the recoil by 50%.-Rob

Rob,I cant figure out how to PM?call me colect if you like....912 925 7537Home

Robgunbuilder,

How do you secure a mercury recoil reducer in a fiberglass stock? Just epoxy or some other trick?

Sir,
Have yoy ever fired it without hearing protection? A customer of mine had a .378 Weaterby with a brake, he removed it because the pain in his ears with a brake was far worse than the pain in his shoulder without a brake.

I am NOT trying to be snotty here, just curious , because if a brake is a must, I really do not see myself building one in the future.

I have never fired my .600OK withiut a brake, but have a Heym .600NE with the exact same load. The Heym's recoil was terrible with the barrel ending up about 70 degrees from vertical. No thanks. I have fired it without earplugs and it was a non-issue. The noise value of a muzzel brake depends on the size, number and placement of the holes in the brake. it you look at the pics above you'll see the holes are about 1/4 inch and produce a series of baffels in the brake. I bet this design is relatively quiet.
Dan- yes just epoxy one into the stock.
Safarikid- I'll give you a call tomorrow. -Ro

GREAT....Talked with ED at length today on details for the .600....Got a pheasant hunt till about noon,anytime after at 912 484 4700....Thanks!

Will do. I am blueing my 12GA FH today so don't know what time I'll be done. Still have some machine work to do on the quarter Rib, but should finish that this am.
As far as muzzel brakes go, The one on the .600OK reduces felt recoil by about 40-50%. As far as loudness is concerned, I have never been concerned as I've always thought guns were quiet when out hunting. If it's a range queen, then I understand the concern. However, I like to see the line jump when I light off a .600OK or worse!-Rob

Safarikid

Well I prefer the 24-25 inch bbl's, even for hunting. My rifles must be balanced even if they weigh a few lbs more. A few extra lbs in a rifle is easier to carry around than excess body weight IMO,

To answer your question, I opted for the GMA action and it performs better than expected. Shot a buffalo in the Dakotas two weeks ago and it dropped faster than if you pulled his legs out from under him. Bullet was a 900 gr Woodleigh soft driven at just over 2200 fps.

Good luck in your selection of options for the 600 OK. The caliber is a lock on great shooting.

Thats different to the break on my .585 Nyati it has heaps of small little holes and while it works great you CAN NOT use it without ear muffs.

Come on over to Yazoo City, MS (you can fly into Jackson and I will pick you up) and you can play with my 600ok. Its a fine looking rifle with excellent workmanship but the chamber on mine is rough (according to ED its a Pac-nor issue)which results in sticky extraction with moderate loads. Im gonna have to do some polishing before I stand before a dangerous critter.

Very nice of you to offer!What specs are yours(weight and barrel length) and what loads are you using?Send a pic if possible Daqridude@aol.com I will have mine in a few months and thats when I will be ready for "The Punisher"....In the meantime,I will just chase "Hogzilla"s brother around with my 17pd .700NE! Thanks Again Pal!

Mine looks like the ones pictured above. CZ action, 24" Pacnor,AHR X Brake,3 position safty, AHR trigger, 2 mercury reducers. I made it up to 170.5 gr 7228SSC/900 gr woodleigh with chrony showing 2158fps. I fired up to 174gr same powder/bullet combo without chrony. It weighed 13.5 pounds unloaded on the scales at the local meat market.

The first set of barrels Pac-Nor made did have some scratches in the chamber area. Mine showed no rings, but rather long swirl marks. Beats me how they did that.However, you can polish them out with 400grit emery paper on a close fitting wooden dowel. Use a portable drill and polish until the marks disappear. Don't get too carried away, but the chamber was not designed to be tight in the first place.-Rob

I look forward to seeing that 12gfh! My boy should graduate machinist school in the spring he is into cnc and such now. I am gathering info on building a single shot from scratch. I plan on necking down a 20g brass shotgun case to 58calb and shooting it with black powder. Nothing that great but should be a good learning exp.
