Talk:Polygonal rifling

rifled or poly?

"...most notable manufacturer to create rifled barrels is GLOCK,"

-- is it rifled or polygonal, in the last section?

Good catch. Clarified. -FrYGuY 23:18, 23 January 2006 (UTC)

I am questioning the drawings of the different types of rifling. While I am sure there are true polygonal barrels, i.e. octagonal and hexagonal, a true polygonal rifling is the same as square groove rifling except that there is an angle in place of the sharp corner. On the drawing of the square rifling, if you start at an inside corner and draw a 45 degree angle to the smaller diameter and do this at all of the corners, you will get a realistic idea of what polygonal rifling is. — Preceding unsigned comment added by Qwaszx357 (talk • contribs) 06:29, 12 December 2019 (UTC)

H&K with lead bullets

Wiki:...However, since neither H&K nor Kahr recommend against lead bullets in their polygonal rifled barrels, it is probable that there is an additional factor involved in Glock's warning...

Heckler & Koch USA Trussville AL:

CAUTION: HK firearms are designed to function with quality manufactured brass cased ammunition. Use of steel or aluminum cased cartridges is not recommended and could adversely affect safe and reliable functioning. Use of cast lead bullets is also not recommended.

I object to reference 2 (regarding lead bullets), as the author himself explains: "Admitting that I'm human, I can't rule out making a mistake in reloading;". Given this fact I do not feel reference should be mentioned as "at least one well-documented catastrophic incident in an H&K pistol[2] appears to be related to this issue." as this seems pure speculation to me? —Preceding unsigned comment added by 83.247.13.48 (talk) 15:10, 8 June 2009 (UTC)

It should be noted that using lead bullets in any firearm can be dangerous, lead fouling must be cleaned frequently or the fouling can cause the barrel to burst once a switch from lead to other types of ammunition is made. Also, hardcast bullets are fine in polygonal barrels, as they are not truly lead, and typically harder. — Preceding unsigned comment added by 74.110.185.248 (talk) 23:14, 29 January 2012 (UTC)

The "Lead bullets and polygonal rifling" section of this article should use much better sources. Issues like this, which could cause and maybe already have caused weapon malfunctions and injury should be written to the highest standards. While manufacturer recommendations are valuable, they are typically so cautious that it's hard to rely upon them as definitive (for example, from what I can tell, most user manuals warn against using handloaded cartridges.) But it'd be better to err on the side of caution, giving too many sources which express concerns rather than omitting the section entirely. Rezin (talk) 00:24, 13 January 2015 (UTC)

Advantages

I heard somewhere that another advantage of polygonal barrels is that they are easier to clean. It seems logical, yes? Kalaong (talk) 04:43, 1 July 2008 (UTC)
