Mark VIII

"[Mk 8 cartridges] should not be used in rifles because the boat-tailed design causes increased barrel wear. The boat-tailed bullet design of Mk 8 ammunition is not in itself a problem. However, when combined with the cordite propellant used in Mk 8 cartridges, which burns at a much higher temperature than nitrocellulose, there is increased barrel erosion" - this doesn't build to a conclusion. Why does the combination of cordite propellant and boat-tailed design cause increased barrel erosion? 91.125.14.118 (talk) 19:29, 30 October 2012 (UTC)

The boat-tailing causes the hot gases to swirl - i.e., there is circulation - in the barrel behind the bullet instead of just pushing the bullet forward, and the increased temperature makes the barrel metal softer where the hot swirling gases contact it. This allows the hot gases, as well as the normal friction of the bullet passing down the barrel, to erode the metal of the barrel over time. — Preceding unsigned comment added by 80.7.147.13 (talk) 19:19, 11 March 2014 (UTC)

The barrel erosion was eliminated by the use of chromium-plated or Stellited barrel bores, hence the use of a boat-tailed round for the L1A1 and other 7.62 NATO guns. — Preceding unsigned comment added by 95.145.115.110 (talk) 08:21, 19 June 2019 (UTC)

Ballistic coefficient

I removed the item "a ballistic coefficient (G1) of .467". The exact ballistics remain unknown, that number ".467" was someone's personal estimation. — Preceding unsigned comment added by Kanadskaja Kazarka (talk • contribs) 00:26, 5 March 2015 (UTC)

New image

I think we need to replace the main (first) image of this article with just a picture of the cartridge itself.

That way it’s less confusing. 2601:644:8000:1566:C97A:A474:4BDD:77F8 (talk) 22:39, 10 August 2022 (UTC)
