Sorry for the late reply. Was travelling.
The market is in Barnet, North London. For sure it is opened
Saturdays. And I think on Wednesdays... such is the UK !
Yes, the other forumnites are right... the pellets ricochet.
I had a lot of fun with my kids' guns. We went to a wood (forest)
behind our home and had a great time. Unfortunately, no pheasants
or game birds to try our luck.
Beware that they do not last long ... but since they cost only a
few pounds, you can get a few at a time to play. The plastic , if
dropped on a hard floor, may crack, and sometimes the spring which
provides the force to propel the pellet will come out of its
housing and it is with only great difficulty that one can put it
back. Remember it is 20 pounds force spring , at least.
