I have been advised to get, and in fact have now bought a Bushnell red dot 1x28 sight for driven boar shooting. I havn't fitted the sight to my rifle yet. but it seems very clear and looks as if targets can be acquired very quickly, my only concern is if the target is further away.

I recently shot moving target for the first time with a rifle using 'normal' 6x and 7x scopes and was amazed how easy acquisition was through them, it was my technique that let me down, not the equipment

So if I was to choose I would say look at what they do on the continent and go for a good quality low mag scope, with reticle that suits your eye.
