40mm UGL Practice Grenade

Over the last few years we have covered a number of pouches and a complete bandolier set up to hold 40mm underslung grenade launcher rounds. Tonight however we are looking at one of those 40mm rounds, an L8A1 practice round:imageSadly I do not have the cartridge case for this round, just the projectile but I am sure the missing piece will turn up soon enough. Complete the rounds look like this:l8a140mmAs this is a practice round, the head is blue to indicate that it is safe and free from explosives:imageThe head does contain a coloured powder however to indicate where the round has impacted during training, usually in pink or orange. Whilst this is perfectly safe it is very messy so it is not advised that you try and dismantle a round. A rubber obdurating ring is fitted to the lower part of the round to help create a gas seal with both the cartridge case and the inside of the launcher:imageThe round works by having a small high pressure cup inside the case holding the propellant, when it is fired this cup ruptures and the gas escapes into the rest of the casing where it expands and produces the low velocity needed to launch the grenade itself. The back of the grenade is slightly tapered and there is a circular void in the base which works with this cup to provide the thrust needed to propel it:imageMarkings are printed in white on the outside of the practice round and indicate the size, 40mm calibre and 46mm long, that the round is a practice round with the designation L8A1 and that it was manufactured in February 2011:imageThe size of this round is a common one used by many grenade launchers and is a low velocity round with a typical velocity of just 249 feet per second. These rounds are not hard to find and can be easily found for under £10 but are very attractive and affordable pieces of ordnance for a collection.
