Being a cadet, I've fired the following weapons:
L98A1 Cadet GP rifle (single shot version of the British Army L85A2/SA80A2). Recoil is noticeable but not large, also fired this weapon with blank ammunition at people (from a safe distance), there is almost no recoil with blanks.
L86A2 Light Support Weapon (LSW) (One kind of British Army machine gun, very similar to the L85A2 but with a longer barrel and bipod, I've fired it semi auto and full auto :D). Same recoil as L98A1.
Clay pigeon shooting shotgun. Recoil is ridiculously large, really hurts shoulder.
Clay pigeon shooting shotgun(s), I actually hit something
Similar recoil to L98A1.
Just so you know, my target shooting is shocking and I can't shoot to save my life (possibly), but I haven't shot anyone yet, at least not with live ammunition (blanks from a distance are safe)
