I just inherited an old Webley Mk3 rifle. I took it apart and cleaned and oiled it and it seems to work OK.

But I don't know if it really compares well to a modern gun for power/range/accuracy (I have no experience of this stuff - but would like to hunt rabbits/squirrels for the pot)

Can anyone tell me if it is worth persevering with an older gun like this or should I just plumb for a newer gun.

Also the gun I have has open sights - it does have a plate spot welded to the barrel - I presume for sights - Is there a specific type of sights I should be looking for - again will it make much difference?

Thanks for any pointers
