Needs Work

Is this page about the M576 Grenade round or the 40mm grenade launchers in general. This page needs serious cleanup. Ultratone85 02:51, 20 April 2007 (UTC)[reply]

Does this page even need to exist given that the same material is covered in Survey of modern US 40 mm grenades? P.S.: The article is wrong about the use of 00 Buck; other sources indicate that it uses 4 Buck. D.E. Watters 16:08, 17 June 2007 (UTC)[reply]

Shot Type Inaccuracy

The referenced article states that this round holds 27 pellets of 000 buckshot--NOT #4--big size difference, and as noted in the article a 12 gauge (much, much smaller than a 40mm--which is 1.2 gauge) has 27 pellets of #4, which ultimately makes no sense.67.101.119.99 (talk) 21:23, 11 June 2009 (UTC)[reply]

The shot cup of the 40mm Multi-Projectile rounds is very small relative to the size of the cartridge case. In the unadopted version, there is only a single layer of shot. In the adopted version, the shot cup is a small capsule centered in a large sabot. We've discussed this in depth in another talk page, Talk:United_States_40_mm_grenades. --D.E.

Pellet weight confusion

The US Army manual "TM 43-0001-28" dated 28 April 1994 quotes the "filler and weight" for the M576 as "20 metal pellets, 24g" on Pg 6-34. I take this to mean that the total weight of all 20 pellets together is 24 grams. This would work out to 1.2 grams per pellet.

This is very close to the US Navy manual "NAVSEA SW010-AD-GTP-010 Small Arms and Special Warfare Ammunition" dated 18 May 2004.

   5-2.6. Cartridge, 40 Millimeter, Multiple Projectile, M576 (B534).
   5-2.6.2. Description. The cartridge is 2.5 inches (6.35 centimeters) long and weighs approximately 1,882.46 grains (122 grams). It is a fixed round of ammunition consisting of an MP assembly and a cartridge case assembly. The projectile contains a polyethylene sabot carrier with a center cavity that contains a plastic pellet cup filled with twenty 20-grain (1.30-gram) lead pellets and covered by a snap-on cap. The cartridge case contains a 2.87 grain (186 milligram), M2 propellant charge and a .45 caliber percussion primer. It is green with white stenciled identification markings.

Individual lead alloys might explain the weight difference, as could rounding errors in English to Metric unit conversions.
