What is wrong with this entry?

I don't think that it's biased, but things such as "You will want to handload" and other sentences are not encyclopaedic. Take "you will want to handload your cartridges, as factory ammunition is not cheap" and replace it with "The cost of these rounds are prohibitive, leading to a high number of handloaded cartridges" and link "handloaded cartridges" to handloader or whatever the article on self-reloaded cartridges is.

Since it is pointed out that a high powered version of this cartridge exists it might be useful to know how close handloaders can come should they wish to approach the one using the special powder. This is partially addressed with the line that says "with good handloads" but doesn't address the point directly.Es330td 20:04, 1 December 2006 (UTC)[reply]

Unfortunately, if you're referring to the Hornady Light-Magnum rounds, handloaders can't safely approach those velocities. They use a special powder and special loading technique and claim to get the increased velocity (usually about 100 ft/sec) without increased pressure. Arthurrh 02:20, 31 July 2007 (UTC)[reply]

I removed "Rifling" from the Specifications section as it is not a specification. An optimum or recommended twist rate may be reasonable included elsewhere in the article.SteveOak (talk) 05:50, 2 November 2015 (UTC)[reply]

Winchester does, in fact, load three separate cartridges in .458 Win Mag:

  1. 500 Grain w/ Nosler Solid @ 2240 fps
  2. 500 Grain w/ Nosler Partition @ 2240 fps
  3. 510 Grain w/ Super-X Soft Point @ 2040 fps  —Preceding unsigned comment added by ASGPhoenix (talk • contribs) 05:45, 5 May 2008 (UTC)[reply] 

re.Tremors (film)
I added a section "In media". I consider this cartridge to be a cinematic artifact exemplary of "classic elephant gun" - exhibiting brute power rather than the streamlined high speed of a military round. I think I may have seen it loaded into a rifle by the character played by Bruce Dern, where the character and his wife are in their basement and terminate one of the underground creatures. If anyone has access to the tape or CD and can confirm this, please state here.

Also, does this appear in White Hunter Black Heart?

The round's appearance seems unique, but I recall this from a pre-1956 B&W movie; one of the Tarzan or Jungle Jim series, perhaps? Were there earlier cartridges with similar appearance?

Any other references?

Additional: In the 1971 movie "Dirty Harry", The character of Harry Callahan uses a Wichester model 70 chambered in 458 Winchester Magnum in his stakeout of Scorpio after the antagonist claims to "... kill a catholic priest". This reference is on the wikipedia "Dirty Harry" movie page.

For firearms and cartridges, the Wikipedia:WikiProject_Firearms tries to avoid trivia/pop culture references unless the particular reference has a major impact on the cartridge/arm itself. In these cases the references would be better put at the referring article itself, for example in White Hunter Black Heart put a link to this cartridge.

correction: The nominal bullet diameter is .458, not .459 as is on the page. ....

According to the sources the diameter is .459 - despite the .458 moniker. AliveFreeHappy (talk) 20:38, 7 September 2010 (UTC)[reply]

The .458 Winchester Magnum is supposed to be able to shoot an out of spec. .459 bullet. This is one of the requirements according to SAAMI. However, the normative bullet diameter is .458 inches. According to SAAMI's specifications the .459 in bullet diameter is the maximum diameter allowable for the cartridge. DeusImperator (talk) 14:21, 14 May 2011 (UTC)[reply]

I believe that the following line in the article:

"By 1970 issues with the cartridge began to surface. Winchester had been using compressed loads of ball powder as a propellant for .458 Winchester Magnum."

is factually incorrect.

This is my first time in this process and I don't know what the next steps are. The basis of my belief is a contemporary article in an American firearms magazine. Lwcutts (talk) 01:22, 5 December 2023 (UTC)[reply]
