As previously mentioned, I bought a couple of Reflex Targets. Pricey enough at 40 quid each but it's nice to have some well made different targets to shoot at. In the video you will see that the dueling target snapped rubber bands. I had great fun snapping them to be fair - I went on to put some extension springs to replace them but these are too strong so I will get some weaker ones. I have also sussed why the rubber bands were snapping - they were working their way down the pole on the move able part of the target and getting wrapped round the bolt head. Cracking fun though and should last a lifetime.
