And the 416 Weatherby pic.

A person could do a lot of nice hunting with a 416 Weatherby---says someone who loads the CZ Rigby up to Weatherby velocities.

RIP, so without reading the whole thread, I am guessing a CZ 550 that was a 458 Win Mag bored out to a 458 Lott if done properly may be the best of both worlds?

Yes, that might be so, but you will have to trim the .458 Lott brass a little short
if you want to make full use of the cannelures on the 500-grain TSX to equal the .458 WIN LongCOL,
to get it to 3.780" COL, which is about as long as the .458 WIN throat will handle.

The .458 Lott LongCOL of 3.730" is obtained when crimped on the second cannelure of the TSX 500-grainer with full length brass.
The .458 WIN LongCOL of 3.780" is obtained when crimped on the fifth cannelure of the TSX 500-grainer.
OK, a special case for sure.
With the 450-grain TSX the .458 Lott LongCOL delivers 3.730" COL when crimped on the second cannelure.
But the .458 WIN LongCOL gives a COL of only 3.680" when crimped on the 4th cannelure.
Best it can do with that bullet and making use of a secure crimp in the available cannelures.
Both of those bullets have same nose, 500-grainer has 5 cannelures, 450-grainer has 4 cannelures.
To make either of those TSX bullets fit into a .458 Lott with 3.6" box, with bullet crimped on first cannelure,
the .458 Lott brass has to be trimmed a bit short, like Barnes recommends in their manual.
So it is more like "a wash."
Unless you are sticking to short and light bullets, 400-grainers and lighter,
then the .458 Lott re-chambering into an existing .458 WIN rifle allows the .458 Lott to win
by using that 2.8" brass to seat the shorter bullets out farther than can be attained with 2.5" brass.
Higher velocity is possible, maybe better accuracy with the stubbier bullets too.
But, I have no complaints with 400-grainers at +2500 fps and good accuracy, from the .458 WIN LongCOL.
I have a Whitworth .458 Lott Like Jack Built.
I save it for use with 400-grain and lighter bullets and up to 3.6" COL.


The WARTHOG .458 Lott Like Jack Built
(only in the chambering)

(Ocular bell barely clears bolt handle when mounted this low.)

If you want a .458 Lott CZ, it is indeed best of all to get a .458 WIN SAAMI chamber and run a .458 Lott SAAMI reamer into it.
That creates a ".458 Lott Like Jack Built."


2.80 cases with a 500 grain TSX seated out long, Would it have enough freebore to crimp in the 4th or 5th groove?.

No, you are limited to the 2nd cannelure on the 500-grain or 450-grain TSX as explained above.
Crimping in the third cannelure gives a COL of 3.840" for the .458 Lott LongCOL and that is too long to fit in the residual .458 WIN throat
in a .458 Lott Like Jack Built.
You cannot even use it as a single-loader.
Some of the old, original, CIP homologation .458 Lott chambers will allow for .458 Lottsmoor COLs of over 4 inches.
That was a for a 2.8" case with the .458 WIN Leade reamed onto the end of it.
The revised CIP .458 Lott is short-throated, like the one and only SAAMI version of the .458 Lott,
which is not the .458 Lott Like Jack Built.

Would give you a bit more capacity if your shoulder desires more recoil.

Yes, the .458 Lottsmoor wildcat chambering was described by member srs shooter.
Perfect for a Ruger No.1 single shot that Kicksmore, and shoots like 450 Dakota factory loads.

Looks like to me all you really need is the 458 Win Mag with a 3.8 inch mag and enough freebore to seat the mono's long.

Yes, that is exactly what a CZ 550 Magnum with a SAAMI .458 Winchester Magnum chamber is.
It allows the 500-grain TSX to be seated and securely crimped at 3.780" COL.
That is just barely off the lands and produces bughole-accuracy at 2250 fps and sub-1.5-MOA accuracy at 2342 fps
from the CZ 550 Magnum factory barrel that I had shortened from 25" to 24-7/8" length and installed on a Pre-'64 Winchester M70.
That is Ms. Chimera WinCZechster, with 3.4" magazine box, shoots LongCOL as a single-loader.



Ms. Alderella Shilen-Ruger, the stainless Knik Knocker, also has 3.4" box length.


Restocked:


I had a CZ 550 Magnum .458 Lott Like Jack Built ...



... but converted it back to .458 WIN with a 25" Shilen barrel:





That is Ms. Bobbarrella CZ-Shilen, with 3.8" box, a six-shooter magazine-repeater with LongCOL loads.





Of course I now need a .458 WIN with 3.6" magazine box length, and maybe a 1:10" twist, all the others are standard 1:14" ...
M70 Winchester, MRC M1999, or CZ 550 Magnum ...
maybe a shorter barrel too ...
decisions, decisions ...
M70 Super Grade .458 WIN, 3.4" box:



Whitworth MkX converted to .458/.416 Ruger due to ringed chamber of a factory .458 WIN, 3.4" box:



Most likely organ-donor rifle, with 3.6" mag box:





More than enough recoil and velocity for most.

I figured the Pecar scope, P.O.R., on the Leavell Mauser would have gotten more of a rise out of you than the BESA Range Adapter, obviously obsolete.

A Pecar with better eye relief than the setup pictured above, hopefully.
I am sure you could tell us which Pecar that might be.
How much forehead would a good Pecar peck if a good Pecar could peck forehead?
Say that three times real fast.

A screw-on/off muzzle brake and some ear muffs and plugs would be more useful for sure than the BESA integral brake and Range Adapter.
Nowadays there are readily available suppressors that go onto .458 SOCOM's and could be adapted to the .458 WIN,
with a thread to match both brake and muffler.
If I run out of material to get to page 459 on this thread,
I will have to get a "silencer" fitted to a .458 WIN,
with a 1:10" twist and try subsonic and supersonic through the muffler.
The .458 WIN sure is "adaptable."

How much H4895 should get me to that original 404 load? Iam guessing 72 grs?
