I went for a walk in the Pentlands yesterday with Steven and Jason, which turned into a 3 hour adventure in knee-high snow with plenty of bemused sheep staring at us. We totally lost track of the path and ended up walking through streams, swampy mud and ridiculous amounts of snow. Along the way we walked through an MOD military training area called Castlelaw, and found loads of spent casings on the ground.
There's quite a lot of information about this ammunition on Wikipedia - it's a cartridge made by ROF Radway Green in 2009, the calibre being a 5.56x45mm NATO. I suspect it fired blank ammunition since it was at a training base. The gun used was probably a M16 Rifle, or a C8 rifle, but there are loads of guns that accept this type of bullet. I wish there had been a lecture on ballistics in the forensic science module since I don't really know what I'm talking about!
More likely its from an SA80 - since that is the standard British Rifle after all. However, if the bullets were expended by Special Forces (like the SAS), then those guns could be/likely to be used. As far as I am aware, there are no SF regiments stationed near the Pentlands :)
This is a blank round from an SA 80.
This is almost definitely from an SA80. It's also a blank round. These are scattered all across Britain, and I practically have a small collection!
