Just got done rebarreling to a 358 from a 243. Was bored at work thinking a 458 win would be fun. I'll never hunt with one or hunt anything that I'd need one, but just something to blow extra change on if I happened to come across a cheap 300 or 7mm.

For those that have, was it worth it? More or less to say I have one lol. Just figured I'd get some input from those that have one "just because"

The great, wonderful, versatile and magnificent 458WM is worth it. See the so titled thread above.

As Fury01 stated they are very versatile with many bullets available today.

I would definitely consider them fun, if you have an interest in larger bores. Particularly if you like tinkering with different bullets and loads. You have a lot of flexibility as to performance level.

I dreamed of big bores since I was a teen reading Finn Aagard, Ross Seyfreid, Charlie Askins and others. Knew I wasn’t going to Africa but still wanted one to play with. Never shot anything bigger than a 300 mag. I found a 458 Lott RSM and HAD to have it. If you’re wanting to play with one, by all means do so. Makes life more interesting which is all the reason you should need.

Didn't even see the sticky🤦‍♂️

I passed up on a 416 rem last year selling locally for only 650 bucks. Went cheap because.. this is iowa lol. Ever since then I was kicking myself.

LOVE big bores. I dont reload but I'm looking forward to my 358. I have my 50bmg, a few 10 gauges. Hunt pheasant with a 16 and 28, I just like the odd stuff I guess. Thinking a 458 will be the next project!

Working on barreling a No. 1 action to 458 Win Mag. Looks like the free bore on this Ruger barrel is pretty long so a 458 WM+ should be doable. Don’t know that I’ll hunt anything with it but I’ve gotten interested in a long COAL 458 WM.

Only other 458 WM I currently use is a Ruger M-77 TS. It’s exactly as it left the factory, nothing fancy.

Why kick yourself when you can get a 458 to do that for you

Not for fun, it's a necessity:

Global Warming, climate change are going to cause the polar caps to melt, The saber tooth tigers and the mastodons are going to wake up.
They are going to migrate to Mexico and the Gulf Coast because , according to the experts, that's where the sub freezing temeratures will be...

Those animals are going to be hungry and horny. You can be a hero or a victim...

LOL OF course build it, it'll kill a deer (If it's legal in your state...).

My largest is a 375 H&H, I've often wanted to build a 416 Taylor. Now I'd re barrel to a 458 WM.

2 things we've learned over the past 2 years: Biden is an idiot, and you cannot count on being able to get supplies, thus with the 416 Taylor I'd have to have a lot of components stored...

Worth building alright, but not just for fun,
it has the best hope for survival of a species of firearm.
Odds are right up there with a species of insect: cockroaches.

From page 143 of "The Square Table" thread where the .458 Winchester Magnum gets a square deal:

What rifle chambering offers the best in practicality in the coming years ?
With the Democraps doing a bang-up job running the supply chain,
we may have to get back to paper-patched cast bullets and making our own black powder at home.
The .458 WinMag cannot be beat for such applications,
as well as being tops with smokeless and jacketed bullets, should any ever get to shelves at your local emporium.
There are more possibilities for making brass from stray H&H-belted cases than with any other all-arounder.
The .458 WinMag is indeed the winner on so many levels.
One thing that bothers me is the primer supply chain, let's go Brandon.

Was a Gun Dealer have had just about any and all caliber rifle in my hands.....also have pulled the trigger on them....
Have always kept a 45 something to just shoot or bust a whitetail.....one caliber that I've always kept dies for and a rifle is a 458 Winchester.....
Whats great about it you can load it up to shoot elephant or down to shoot a deer even a woodchuck in the wood lot even cast some bullets to just poke holes in some paper targets....

Well I think you guys lit the fire lol. Now to search for a cheap rifle or action

I have two 458’s, a Mod 70 458 Win Mag and a double 500/450 3 1/4” NE.

Along with a few 375’s the are all good fun!

Enjoy yourself.

Go with the rifle. That way you can have some fun and get a better idea about whether you really want to build one of your own, without dropping a bundle.

The .458 bore is a wonderful thing, but unless you have a specific purpose in mind, one based on a smaller case will be more generally useful and portable. A .458 WM rifle has to be built strong and heavy enough to handle the recoil of full-power loads. Even if you plan using mostly or even only lighter ones, is a rifle that size something you want to carry around? If not then go with a .45/70, or if you want a bolt gun, a .450 Marlin.

Some years ago an LGS had a very nice Ruger #1 in .458 Lott in the used rack at a nice price. I always thought one of those was a good idea for shooting BP or light smokeless loads. Picked it up and then put it right back. It was a handful, much more than even my younger self would want to hunt with.

Contemplating this stuff is at least half the fun. Enjoy.

I bought an Interarms MarkX in 458 Win mag, just for fun as I have no use for it otherwise. Mine has a B&C synthetic stock and shoots very well. I mounted a S&B 1.1X4 straight tube scope on it. Very well balanced rifle that shoots very well

One of the benefits for a heavy caliber rifle seldom if ever mentioned, is that it provides an opportunity to self scrutinize your own ability and teach you by forcing discipline into your routine. The act of holding the rifle in a position of control, the methods of staging for the rifle support, comfort, eye alignment, concentration on the target as a more major factor and priority than worrying about recoil. Most importantly, learning to squeeze the trigger during that period of concentration on the target so that the firing is less expected and flinching is eliminated from the shot.

This is real and possible through various methods of assistance such as working up loads or using lighter bullets to begin with but it can be done and you will never realize the accuracy potential of your rifle until you begin to manage it and not fear it. You also have to learn a reasonable shooting period or number of shots as a reasonable session, as this will never be an all afternoon varminting rig though will do spectacular work on targets of opportunity.

Never forget, "Designed by mortal man for use by mortal man".

I wrote a review on those when first released and broke 2 stocks at the wrist during the review which the importers gunsmith took very serious note of at the time. Wish I'd have bought it now, as they were great shooters albeit, very light rifles for a .458. Our importer also brought in .375's at the same time but I was the big bore guy, so the .375 went to another writer.

As to myself, the 458 Lott was and still is a learning lesson for me. Off the bench, it definitely lets me know when short cut the set up.

My 458 Winchester & Lott interest is with the 400 grain and below bullet weights. I still find the recoil lively in the 2500-2600 + fps range. My rifles with scopes are in the 9.5 -9.75 lbs range.

If I found the right deal I’d be interested. I hardly ever even use my 300 WSM, prefer smaller cartridges. My idea is a 375 on up.

At least as an avid reloader, I can keep things reasonable for casual shooting.

OP, build it! You'll enjoy it. Load it down for fun and up if going where you might need its capabilities.

Had a 458, never really warmed up to it. I do like a Whitworth 375 a lot though. Versus building I'd just buy an existing one, scratch the itch, and if you feel like selling down the road you won't get hosed. My old Ruger seemed like a well built rig.

I’ve had two 458 Win Mags and had fun deer hunting with them. However after hiking on friend’s ranch in Montana I built a good bear stopping rifle in 458 x 2 American on a Ruger 77 Mark II short action. Light and easy to tote on a hike in the back country. I built it two months before the announcement of Marlins’ 450 Marlin cartridge, which would be the more affordable round to build on today.

I have a 458 Lott in a Model 70 and a 458 WM in a Remington 798 just because. Both at great deals.

I also had a Mark X in .458. I had no need but fun to play with. I took some smaller game with that rifle, but after suffering a Severe whiplass injury & going thru several versions of treatment, I saw a Neurosurgeon. I asked him how long before My problem would go away, he said "HELL SON, IT'S NOT GOING AWAY". After talking with me further & questioning me about my LIFESTYLE, he told me to stop playing around with that ELEPHANT GUN, if I wanted to live a halfway healthy life !!!! I did as he said.

To be honest, I think every shot I've taken or considered taking probably could have been accomplished with my 6.5x55. Definitely with my 30-06. I absolutely haven't needed anything more powerful than that. Unfortunately, I found out that I like rifles that make a big boom so as a warning, it can be addictive. I got a 9.3x74r & loved it. So I bought a 375 H&H. I liked it so much it turned into a pair of them. Added a 405 Winchester to the mix & the fun didn't stop. So now the 458 WM enthusiasm of some of the other posters in this thread has rubbed off on me & I'm currently building one out of a Ruger M77 MkII. Just because!

Intuition tells me that at some point, I'll reach a threshold where I'll tell myself "Well that was unpleasant..." but I haven't made it there yet. Much like my love of spicy food and the progression from jalapeños to habaneros and on to ghost peppers & Carolina Reapers, there's a mindset that if too much heat is fun then more is going to be even better...until one day it isn't.

If you want some fun, buy a Ruger No. 1 and rebarrel it to 500 NE! Just don't shoot it wearing a T-shirt.

Not sure if the OP ever followed through, I hope he did.
I was gifted a few big bores when a long time friend passed. One, a 4 diget BRNO in 458, being one of them. Not real practical in CA or western hunting.(it's not even D&T'ed) One thing Not mentioned about the fun factor is letting someone else shoot it at the range. The grins and the groans can be a real smile maker. Haven't shot it in a while, going to have rectify that. One of the other big bores I received was a CZ in 416 Rigby. That one is a bit expensive to pull the trigger on.
