I'm a beginner to shooting myself, however I am a member of a club run by mature gentlemen to be polite, so I asked before I bought a springer, something I was told was that a fixed barrel i.e. underleaver should be more accurate than a break barrel as the main gun barrel doesn't move when cocking the gun.
I bought myself a Weihrauch HW97K, with which I'm very pleased, the only problem for me is that the weight of the extra underleaver barrel makes it a bit heavy after a while.
