For those of you who don’t know I bought Safari Kid’s old 9 pound (unbraked) 600 OK…

With some guidance from Rob I’ve been working up loads. I decided to stop at 2050 fps…

Lets see…900 gr bullets @ 2050 fps, 158 grs powder, and 9 lb rifle…equals 216.04 ft/lbs of recoil energy !!!

I’m sending the 600 OK back to American Hunting Rifles to have a brake installed and a few pounds added to the stock (sorry Tom, but it’ll still be light), I guess I’m becoming a pansy …

All kidding aside this is a great rifle and cartridge…

AHR does a great job…

Even though recoil was stiff I was able to maintain total control of the rifle (unlike some of the poor fellows in Saeed’s T Rex Videos). Good stock design…

It feeds and ejects 100 percent (my first big bore CZ to ever do so)…

The AHR trigger and three position safety are great…

Overall a mean little machine…maybe a little to mean…

And as for the 600 Overkill cartridge…

This just has to be approaching or is already the final chapter of "practical" stopping cartridges…

Just thought you’d all get a “Kick†out off this…

I need a cold beer…

Matt V…

okay, you're a pansy...

Seriously, I would expect the recoil level to be a bit, shall we say, intimidating...?

You have the recoil equivalent of that old Jan & Dean song; "...well, the last thing I remember doc, I started to swerve...and then I saw the jag slide into the curve...".

Just be glad you were in the stingray instead, you came back from "Deadmans Curve".

In six to eight weeks I expect I will be touching off the 875gr starting loads in a ten pound 577 Belted Magnum Express...I will then be able to empathize with you fully.

The adrenaline rush must be tremendous!!

rich...the sd on the .585 875's will be .365
to get the same sd in the 600 you have to go to almost 1000 grains!

Rich,

Tremendous is an understatement...

You'll be up there in recoil, don't let anyone kid ya about brakes either...

Boom Stick

Hawk Makes 1000 grain .620 bullets...

Sd .372...

Matt, would you be interested in buying a used X brake for the 600? I removed mine and dont see myself ever using it again (my rifle weighs slightly more than yours). You can save yourself a little change and help me keep my gun room uncluttered!

remember, the 600 NE is "only" 1850 or 1950, unless one is marky shunkivan, in which case it's 1500...

if you can shoot it at 9# and 1850 FPS, well, i think we could get some of our double rifle only buddies to back down on the "doubles kick less" point of view!!

jeffe

Oh lets see, I've driven a 1000 gr solid brass Bridger Flat point through what 60 inches of hard oak log. Recovered it from the dirt backstop and probably could have re loaded it and shot it again. I could have run a steel rod through the hole it was so straight. Guess I need more SD just incase a Armoured Tank gets in my way. Yup more SD sure is necessary-NOT.
2050fps without a break is about anyones limit of recoil. The ol .600Ok has way more horsepower on tap too. AS I've said before, at some point your survival instinct kicks in and you stop before it hurts you. Notice how well the gun is designed too. Recoil comes straight back, not up and out. About 10 years worth of DGR experience went into designing that stock.
For fun I still like the 165 gr of IMR7828 load with a Woodleigh 900gr softpoint. You can split 24 inch diameter logs with one shot with that one and it hits only 1950fps!-Rob

OUCH! Pansy? I don't think so!

Yeah ... I agree ... that ain't no sign of being a pansy!

I think my approach may be a little weak knee'd. My comfort and rapid use level is about maxed at the .458 AR and Searcy's old heavy loaded .470 (500 at 2250).

I think the guys that are lookin' for the recoil-driven adrenalin high have just found the extreme sport of the firearms world. Makes about as to me as tryin' to surf the wave from a fallen glacier wall. OH well, different stroke for different folks

Here I thought the 378 and 460 WBY were nasty. 216 ft/lbs is pretty much double a 460, yikes!

Guys, I’m joking about the pansy comment but I’m not so macho that I can’t admit 2050 fps is about my limit…

I want to get up in the 2200 to 2300 fps range, but the rifle has to be braked for me to go any farther…

Mississippian,

Thanks for the offer but I’ve already made a deal with AHR and don’t want to go back on them…

Jeffe,

“Well†is the key word…I’ve never shot a double (would love to) but 1850 fps in this rifle is completely controllable. The recoil comes straight back and muzzle rise is almost non existent…

Rob,

When I get the rifle back I want to finish working up my 900 grain loads for deer season… Finally got a box of Woodleigh softs…

I’d like to try some of those Bridger solids though, sounds like a lot more fun than running a hydraulic log splitter!

Matt V.

I just have one question! Will any of these cannons ever poke a hole in an animal, and where would one find an animal that would require such an artillery piece?

My guess is paper, and logs will be the targets for the most part!

MacD37, click on the link below my signature and you wil see one little animal that had holes poked in him by a 600 OK. Another 600 just returned from two weeks in Tanzania poking holes in various beasties. Another is about to leave for Tanzania to poke more holes. I would assume " require" equates to "need" and need has nothing to do with it.

MacD37- You been a bit sleepy? Remember, focus,concentrate, the .600OK was designed for Buff and ELE. As you know, the animals themselves asked for it and require its existance! .600OK's have poked a few holes in lots of animals over the last 5 years. Probably about as many now as the ,600NE. At least 30 of them have been built at this point. I should start a Registry soon too before the BOZO's deceide they invented it and claim credit for it.
TH50000- One word of advice on shooting deer with a .600OK is aim for the paunch (really) if you use a softpoint.150-200lb Deer simply blow-up. Ask Jeffe! No need to gut em after that shot. This thing delivers a tremendous hydraulic punch with softs and deer essentially vaporize. A good cast lead bullet made of linotype would be a much better approach. -Rob

Your a good man. Good luck with your load development!

yet marky sullivan's 600 NE, at 14#?? and shot at an "honest" 1600fps LOL kicks the snot out of him... even if it's loaded to 1850, it's still brutal to watch him shoot... while the boltgun 600 OK is "plesant" at 1850

Rob split a big whitetail doe with a 585 nyati.. hit her on the last rib. she split from sternum to tail, guts fell to the ground, quivvered for 20 seconds, and expired, without moving from where she stood

No argument from me...

OUCH!! FRIGGIN' OUCH!!! A muzzle brake sounds like a good idea.

Gentlemen please do not take this the wrong way! I'm not putting anyone down for his or her choice in rifles, that is a personal thing, many do not like my choices. But my comments, or question was in regard to actual use, on an animal that would require it!

I have no doubt these cannons will kill things, that is a given! I also have no doubt that some of you guys will actually shoot something with them other than paper, and logs.

Saying these things have taken more game than the 600NE is not surprising, because the 600NE is a rare bird, and not needed in the field either,IMO, and I suspect need is actually "WANT", for these rifles as well! I, also, understand that a NEED, is not necessary for a man to own, or hunt with one of these rifles. My comment about "REQUIRING" had nothing to do with one's choice to have one or not, but my question was in regard to an animal that would require such power, in even the direst of circumstances! IMO, no animal on the face of this earth REQUIRES anything larger than a 500NE.

That doesn't mean one can't hunt them with them, or with a 600NE, 700NE, or other wheel-less artillery pieces. There is no accounting for what turns people's cranks, but lets just say it like it is, need has nothing to do with it, it is WANT, and the real reason for anything bigger than a 577NE, is simply because it is a "LOOK AT ME TOY", and fun to play with! There is nothing wrong with that, but I still have my doubts that, for every 30 of these things built, more than one or two will ever hit anything, live, bigger than a deer, or wild hog, and most will hit paper only!

There is nothing wrong with that either. I once used a 577NE to shoot an elk from 30 yds, after he was called in, but I had no misconception that a 577NE double rifle was required for an elk, because I don't even think a 577NE is required for even elephant, even though it may be fun! In the end fun is what drives this type of thing, and that is justification enough, but lets not declare any need for them on any animal living today.

My question is still, what animal on the face of the earth requires such a chambering, because Buffalo, and elephant do not require it!

Please no and flames!

Blue Whale burgers are really nice when they are sauteed with a bit of fennel ...

MacD37, The 600 OK and the like are just lots of fun and extremely accurate to boot. They are addicting.
How boring to shoot only what is adequate to kill.

A Yugo would get you anywhere a Ferrari would also.

Boring, to some maybe! 10 yds from a wounded cape buffalo with a 470NE double in your hands is not boring to me! The punching of paper while enduring the recoil of a 600 cal rifle wouldn't be boring either, but it would be a little uncomfortable after a few shots!
