Generally two ways of target alignment :
Sub 6 where you aim somewhere below the black - easier to pick your sights up
Centre hold - where you aim dead centre on target - harder to pick your sights up

I've tried aiming below the black and I'm getting some sort of grouping, but if I use a knock down target do I try for for the centre hold?? If so what do I aim at ...the target..and line up my sights accordingly .

Sorry for all the questions, but I have a word with St Michaels in Lynn and will endeavour to pay them a visit.
