Martwizz , you aint nutz , i'm a aussie but had mates in Brixton until they relocated for safety ...
the jihadis there are still coward but attack when they have group courage ( in numbers only) the shotgun and semi auto .22 are a good call ,
take a look online (here's my site http://minus.com/jack404
) and look for Phil Luty
Phil was one of yours, a great guy , fought against the stupid gun laws and got gaoled for it a couple times, while rapists and such walked ..
the plans he put together would come in handy in a SHTF situation
make em yourself , part make em and keep em in parts until needed , but keep em so you still need to do some small parts to make em work
your shotty and rifle will hold you for a few hours .. ,
cheers , stay safe eh , bad times are a coming your way ( here too in oz eh)
