Yep I'd tend to think that posting your address linked to this kind of forum isn't the best idea in terms of maintaining security regardless of whether there's posts about amounts of ammo.
It's not a personal dig as lots do it but seems odd to have a burglar alarm but then post all this info (including the make of burglar alarm ;-) )
If a criminal is going to the lengths that you lot think they are to get at his guns what's to stop them following you to/from the range and taking your guns en-route? Or following you home, knowing you have guns, likely ammo and a safe that probably conforms to the British standard?
If you're going all tin-hat you may as well go all the way.
theres about 10 houses on my road with adt alarms and I could jusy be talking bull to feed the fire . And hey I might of moved since and not updated my profile . You would be better off going on my facebook to find more info
