The metalwork is almost done. My 'smith made the brake and mounted the front sight.

















All that's really left is either filling the bolt knob or replacing it with a larger one. We haven't decided. The stock is finished, except for checkering.



I shot it on Mother's Day, but I will put up my pics of that in another thread so the threads will load faster for those of us on dial-ups.

Shooting the .600 OverKill

Very nice.

I want a picture of the bullet!

Looking good!



Note to the recoil shy - look at the recoil-controlling features of this rifle.



1. It has a straight comb without much drop. Drop in the stock creates a moment arm and pivot point around which the muzzle will swing during recoil, exacerbating muzzle rise. This .600 will minimuze muzzle rise due to the lack of drop in the stock.



2. The stock is wide and beefy, especially at the butt, thereby spreading recoil out over a larger surface area of human flesh. That means less compression of any particular piece of flesh, and therefore less felt recoil.



3. Extra thick recoil pad, which I assume is probably made of the energy-absorbing sorbethane molecule. This allows the rubber pad to soak up a lot of the energy of the recoil, rather than having movement of the human body serve that purpose.



4. Mercury reducers in the stock. The liquid mercury is stationary when the trigger is pulled. The rifle will recoil rearwards some distance (maybe an inch) when the end of the mercury tube will slam against the stationary mercury liquid. The stationary mercury liquid, about a pound and a half of it in this case, has inertia which must be overcome by the movement of the rifle. Overcoming the inertial of the mercury uses up some of the recoil energy of the rifle, decreasing felt recoil. Also, the slamming of the mercury tube against the stationary mercury reduces recoil acceleration of the rifle.



5. Muzzle brake. A good brake reduces the jet propulsion effect of a cartridge with a large powder capacity. A good brake also reduces muzzle rise.



6. No scope. Nothing will make a guy more skittish than a steel tube moving towards his forehead with 125 ft. lbs. of energy stored in it.



George, the rifle looks like a fine result. Congratulations!

Lucky you
Looks like lots of fun at the range that day.


Cheers,

By the way, I have shot the .600 Ok with a leupold 2.5 compact scope with no ill effects. You have to lean into it a bit with your weight slightly foreward on your feet and rock back with the recoil. The muzzel will climb but not enough to hurt you.-Rob

George, what action did you build the 600 Ok on, and how many in the magazine, two down??

Great looking rifle!

George,

I couldn't help but notice the beefy recoil pad on the 600 OK. Is that what Pachmyer calls their Triple X (XXX)? I have seen this pad on a few 50 BMG rifles and have found them to be very well engineered.

Thanks for the comments, guys.

Dakota,
It's a CZ550. It holds 2 down and 1 up. Without a drop box that's all you can fit.

Wyo,
It's a Kick-Eez, it's the largest pad(width and heigth) that we could find. As 500grs explained above, larger area is better.

George do you intend to test it to provide mamximum load data ?
