.550 magnum caliber?

[Texas Sharpshooter Fallacy]

.550 magnum built on a CZ 550 magnum action. Cartridge is a .460 Weatherby necked up to .550.

Anyone have any experience with these on the big thick skinned beasts? Seen a couple used bouncing around online and I know that AHR builds them as well. Read that they pack quite a wallop and recoil is relatively mild given the pressures and fact they are usually built heavy.

I made the mistake of shooting big bores a number of years ago, found that I enjoyed it, and kept acquiring more. My .375 H&H and 450/400 NE have dropped a number of animals. My 500 Jeffery just paper so far, but plan to change that later this year in Zim.

Of course, I don't need anything bigger but these are the types of conversations that are supposed to occur here, right?

My only experience is handling this one round I was given by Wayne at AHR a few years ago. Here's a couple of pics for your enjoyment.

One of my former students is friends with an African professional hunter by the name of Mr. Jason Van Aarde . Mr. Aarde’s backup rifle of choice is a .550 Magnum , which is built by Bloemfontein Custom Rifles on a BRNO ZKK-602 action . It launches a 700 grain bullet at a velocity of 2240 feet per second . The gentleman prefers custom brass bullets made by Johann Kriek for this rifle .

Mr. Aarde is quite a seasoned dangerous game hunter and can never speak too highly of his .550 Magnum . He owns H&J Safaris .

700 grains at 2200 fps will put a T-Rex on the ground. Sounds like quite a stopper.

7800 ft/lbs of ME. Actually a tad less than full power .460 loads. Bigger, heavier bullet though....

Seems to be very similar ballistics to .577 NE, just a tad more powerful. No need to reinvent the wheel.

I think the exact same thing can be said about your 500 MDM in relation to the 500 NE.

If you can handle it, go for it! Impressive ballistics.

Not too many 577 NE in bolt actions though...

Not sure if jaco @KWALATA SAFARIS had one built

They had one on the cz booth in their custom rifle rack at sci few years ago that was built for someone...was nice ...they tried to get me to buy one but had bought a 500 jeff from them year before..also don't hand load..so managed to escape that one...

Would make one helluva squirrel rifle

That CZ listing prompted me to look into the .550 Mag. It's got a motor on it, Lord.

Recoil mild ? lol Well if you have a 500 Jeffery you know what you're getting into.

I think someone posted the .550 was sold, and I hope someone here bought it. As mentioned on that thread, woukd not have been a bad price even if you looked at it as just a barreled action by a very talented ‘smith.

I think Krish has or had one.

 

[Luvthunt]

I wonder if Wayne still builds the 550?

Some states (in the US) limit deer hunting to straight wall cases.

Some states (in the US) limit deer hunting to straight wall cases.

And I thought we have issues.....

 

[CoElkHunter]

Some states (in the US) limit deer hunting to straight wall cases.

And most of those states limited deer hunters to shotgun slugs before the straight walled cased cartridges were approved over the last several years.

I’m not giving you a hard time, l just don’t think the 550 would be my first choice for deer. Just saying.
