Driven boar, Aimpoint . When you compare the price of a quality site like the aimpoint to a quality scope the aimpoint is very cheap. I used to use my big S&B flashdot for all my shooting but now only use the S&B for sitting out at night for boar.
Its only when you use a sight like an Aimpoint or the 1- 4 x 24 type scopes it makes you realise how badly balanced and top heavy a rifle becomes when mounted with the modern monster scopes. The big scopes with illuminated reticle do come into there own for sitting out for boar at night.
