Well, gentlemen…… I’ve seemed to have reached an impasse….. for those of you out there who’ve handled/fired and know of those who own/have owned a 600 Overkill bolt action rifle, would rather have one built or buy one that’s already made from someone who has taken care of it?

I ask, because I can’t decide whether to have one made or to just seek one out from a private seller.

I’ve tried contacting Bijou Creek, but to no avail I’ve yet to receive an answer or make contact with Mike. I have spoke with Jason of Aria Ballistic Engineering as well as Corey from Boyou Advanced Weapon Systems. Seems like to have a 600 O.K built (if it were to get started tomorrow) would take roughly 24-40 weeks and run north of 15k for the rifle itself EXCLUDING brass, dies, and bullets. These estimates really make me lean more toward finding a used one over a new one.

I’m nowhere near a perfectionist nor am I overly in particular in the details of what I would desire in one of these rifles. I appreciate craftsmanship, but value functionality/dependability way more over a showcase piece. I think that if I’m going to plan a build or try and locate one of these I need to start sooner rather than later (just cause I can and it’s already been on the bucket list of rifles for quite some time).

So, if it were up to any of you guys (if you were remotely interested in one of these big bore behemoths) would you prefer new or used “new to you”? And why?

Thanks in advance for the opinions and I’m looking forward to the conversation!
 
In my humble opinion, most guns made in this chambering are too light. So, i would have one custom made if i was interested.

It should be mentioned i havent shot a 600 OK, just a 600 NE.
 
Sadly you just missed this one by a week.

CUSTOM CZ 550 SAFARI CLASSICS 600 OVERKILL BY AHR https://share.google/dLSrlRLLc5l5EHyM0

It was an absolutely stunning rifle that Wayne built for himself. I've seen it in person several times when he would bring it up to my Safari shoot.

Good luck with your quest, I draw the recoil line at my 505 Gibbs. Like Clint Eastwood said, a man's got to know his limitations. :)
 
I've had my run ins with big bores, but have not been able to touch off a 600 Overkill yet. Most that I've talked too, prefer the GMA action to anything else out there, which I've heard of feeding issues with the CZ-550 action but maybe that is exaggerated. So most of these guys are using that action ($4500 or so), then one has to pick a stock, which can be however much to plan to spend on the wood, and then the actual fitment to the gun. So their prices are about normal with what they are having to do to the rifle to make it all work.

Ultimately, you will most likely find one cheaper than you can have made for yourself. I'm currently building a 585 Hubel as I have excess brass and that is going to be an expensive project as well, and if you're anything like me I'm a wood fiend, so I only accept the best.

The best way to look at it, is this going to he a heirloom? If so spend the money if you can. If not, then find one at the right price!

Good luck on your endeavor, might be a good idea to reach out to @buckstix.
 
Yep, you missed it big time. My 600 Overkill had a pre-auction estimate of $6,000 to $10,000 and sold for less than the $6,000 low estimate. To build one from scratch (if you can find a builder) will cost $7,000 to $10,000, and you have to supply the now rare CZ550, or similar rifle, to start with - and then wait 24-36 months to complete. My little red overkill came with a $700 Leupold red dot sight and had a CZ peep site. Now I'm waiting for the lucky buyer to contact me for dies, brass, and ammo. I would have been very happy if a member here would have gotten the great deal.

WOW!!! Yep, I missed one heck of a deal for sure!!! I wish my mind would have been made up long before this week!!!!

I totally agree. When I acquire something, especially a wildcat big bore, I always look at it as an investment so it’ll last and hold up to its standard.
 
So far is is looking like it’ll be just as easy to ask around seeing if one might be available somewhere still be to build one.

Lead time is pretty far out, and GMA actions if gunsmith(s) order it or if I ordered one directly from manufacturer for the build will be a painful 16-32 weeks till it is ready to even ship. Thats a long time to wait on one.

If anyone knows where one might be for sale or if anyone may be willing to part with theirs, don’t hesitate to let me know. My eyes and ears are open.

I’m thinking If I don’t get any leads on one by June, I’ll pull the trigger on a build.
 
I still have another original AHR 600 Overkill built by Wayne Jacobson, but I'm not selling it at this time. Wayne is now retired and not building any more custom guns. No more AHR. When I sell this one it will be $12,000 to $15,000.

Yeah, Wayne’s synthetic stocks are some of my favorite synthetics ever crafted and although the initial pricing was very close to his wood offerings, they don’t do near as well on the used market. I still have one synthetic AHR and it is extremely well executed. That was still a crazy low price and the fortunate buyer could commission a fine custom stock and still be ahead.

I would wager that 90%+ of .600 OKs were built on 550s and Wayne built a vast majority of them. The GMA is a far superior action in general; however, the .600 OK was reportedly specifically designed for the 550. Wayne knows what he is doing and I have not heard of any issues with any of his .600s, including from Tom Ordes, on the handful of 550s he owned.

Sure the design of the cartridge was to milk everything you can out of the 550 and it accomplished said feat. I never mentioned Wayne in this thread, but since you did, Wayne prefers the GMA to the 550 anyways, but the 550 is the more affordable way, atleast back in the early days of OK and they simply work. A buddy of mine had a rough go with his 600 OK, but I'm unsure as to where acquired his, or if he was loading properly to boot. Too many probabilities on that one, but glad to hear that others have had a great go with their's.
 
Here is more info about my 600OK, along with a short video showing the shooting (not me)

Mine is like the one in the video. Its built on the CZ 550 action by Wayne, and it feeds smooth and 100% flawlessly.


The 600OK puts the 577 T-Rex to shame. My target shows a fun load that's about 850 fps less than Max.

Later I added a scope.

More power to you guys shooting the bigger stuff. My limit is the puny Lott. LOL
 
I survived three retina detachments in left eye ... barely. I don't get much from it now but depth perception. Also several laser patch ups to both eyes and those are extremely painful. Torture actually.

If you are near-sighted or diabetic, you are high risk for detachments. At age 31 not as risky as 51 but spontaneous tears and detachments can still happen. A ruined eye can seriously impact your job and family. Going blind more so. Almost ruined my domestic situation when the surgeon told me to prepare to go blind at age 52. I didn't handle it well. Thankfully my late wife was made of better stuff than me. They say it's a miracle I have recovered. I was given the okay to resume shooting years ago, but I'm not pushing the envelope. I do shoot a 3" mag 12 ga shotgun a lot for everything (including trap loads at the range) but I switched to the heaviest auto ever made for recoil mitigation. The 404 I recently built (for the fun of it mostly) only gets fired on rare occasions. My 30-06 usually just enough to get it zeroed.

Be careful.
 
I am 74 and get regular eye examines because I am type 2 diabetic. My eye doctor says if you have "questionable" retinas, a sneeze could detach them. He also said shooting, even the big stuff, isn't an issue with healthy retinas. He has seen my 600 OK, and my 700 NE, and my 8-bore, and said not to worry.
