Airgun pellets are much larger and slower than bird shot, which is why shooting at hardboards is not a good idea. Lead could of course ricochet but it is highly improbable because it deforms on impact and will generally always have plenty of forward momentum left and so will bounce in an away direction; this is why shooting below rabbit targets is so effective. Now to glasses, I hate them with a passion. I entirely understand and agree with the safety angle but personally find them a complete nuisance as they won't stay on where I like and creep with recoil, also find the rib sits too close to the corner of the nose piece instead of centrally unless I wear big, high types like my present Hydefspex. What I have never found is this magical property of turning clays into dayglo objects, to me that's just marketing bull as is the ability of the arms to mould themselves to the shape of your head over time/wp-content/forum-smileys/sf-confused.gif, mine are as uncomfortable in this regard as they were when new. I also had to radically modify the nose piece to prevent marks on my skin every time, pretty unforgivable given their extortionate price. If you look carefully you'll find a lot of famous shooters don't wear them in non registered shoots.
