It could be fun, but only if you add a foot to the barrel and make the rifle itself about 15 - 20 lbs. With an 8 lb. CZ it's just a boat payment for an orthopod.

the 600 overkill is a registered sporting cartridge so you don't have to register it as a DD.
wayne a AHR has probably done more of them than anyone and unless your smith is very good at making big bores feed i would give the job to wayne at AHR or to bijou creek.
if you do let your smith take on the project and it doesn't feed make him stick to it until it does.
most people run them with a 20 or 22" barrel and a side fin brake. the brake adds about 3" to the barrel so a 20" barrel is just about right.
a couple of the guys i shoot with have had them built by AHR & Bijou Creek.

I voted for the 16 inch.
You should get it down to around 6 or 7 lbs.
It would make a great moose or elk gun and you could carry it around in the mountains hunting.
Make it a scout rifle.

I don't know if that would be possible. The receiver itself weighs over 3 lbs. I figure around 2.5 for the stock and 2.5 for the barrel would make 8 lbs. Not sure where I could shave any weight from that and still have everything strong enough.
The 600 Overkill is designed for a maximum chamber pressure of 65000 psi. The barrel has to be pretty hefty to take that kind of pressure.
The receiver came in. Trying to decide whether or not to do any customizing while waiting for the barrel to be made. Think I might just smooth out some of the edges and clean it up a bit.
It's amazing how big this action is. In the lower picture it's next to a Winchester Model 70.

Ok IF you want to do it here is my advise:
Use a big thick blank of walnut/maple laminate or solid laid up fiberglass. This will make a nice dense and LARGE base for the cannon. Keep the shoulder width contact wide and tall! I would go 1 1/4" thick x 20" long plus a good muzzle break which is gonna add 2-3". I like Gentry Brakes but others are real good too. So now the weight is up to around 12 -13 pounds . The large stock dimensions and reasonable held weight for off hand use will bring the recoil down to useable levels and still have quite the compact gun if you keep the length of pull down around 13" .

loaded ammo is available from ahr. i would also use one of their x-brakes or another style of side fin brake over a gentry.

Agree on the brake choice. Maybe you should look up Col. Art Alphins work on stocks for big kickers.
I suspect that anyone reading this thread has probably seen this, but IMO it never gets old:

In the original post he says he has become bored with the 460wby as a range gun blasting grapefruit. He wants maximum recoil so I am thinking this new overkill rifle will not have a brake because then it will not produce the maximum effect.

...or anti-tank weapon.
No offense to the OP, but methinks you are crazy. Your money however.

Between reading about this and seeing the signature of "LeonCarr" i'd say this is a Chuck Norris gun. All jokes aside, looks like it will be an impressive build. Definitely following this.
Thanks, I think Chuck Norris would just use it as a BB gun though.
Get a hold of Safarikid at Accuratereloading. He had one built with a 16" barrel, and it made the handiest Alaskan rifle, ever. Great thing about those big bullets is they don't need a long barrel to burn powder. They provide enough resistance all on their own to allow the powder to burn, before moving.
No reason to have a really long barrel. On the otherhand, IIRC the original Overkill used a 28" barrel, and created some really incredible ballistics, at low pressure.
The muzzlebrake is the whole deal. Without a good one, you have a separated, or broken shoulder.
Also the recoil pad, and butt end have to be very big, so the recoil is distributed over a large area. Otherwise you might as well take a 2x4, put it in the shoulder joint, and hit it with a sledge hammer at 150 ft per second.

It's the perfect rifle to have should you ever pull a permit to hunt Jurassic Park.
Where are you getting ammunition?
I just got sticker shock trying to find ammo for my 375 H&H.
By the way, this is the Class 5 economy stopping rifle. Uses pretty much a brass shotgun case, with a .577 bullet. So, it's what the .600 Nitro Express should have been.
You load a 900 grain LFN at 2150 fps and you have a stopping rifle, the best pretty much ever, or this side of a 4 bore. Certainly the most packable stopping rifle, ever. I'd go with a 18" barrel, and brake.
Don't know if a 900 grain soft point is enough bullet weight to penetrate for what the gun
is designed to shoot, but, at least when you hit that elephant, or bear, he's going to go down, giving you a couple seconds to aim again.
You REALLY don't need expanding bullets with a LFN in .577".

I'm going to load my own. Should get the cost down to about $2.50 a round. Factory ammo is $13.75 a round. Even counting brass and dies, it will only take about 60 rounds to break even.
By the way, the 600 Overkill shoots a .620" bullet not a .577". It's based on the .585 Nyati case blown out with a belt added.

600 Overkill
Hope you have better luck than one of my customers, he was using a 500NE shooting hogs in E. Tx. practicing for a buffalo hunt in Africa and blew both his carodid aretery's out and had a stroke. Did'nt make his Africa hunt and never will. Al
