It's not uncommon to hear stories among seasoned springer shooters about how their gun shoots x inches low / high / left / right etc when they take a standing shot as opposed to a sitting shot.
Same gun, same fixed scope, same person pulling the trigger - Different Hold
I guess to a far lesser degree the same is also true of PCP's but the difference is so slight you probably wouldn't notice it.
Ahh, now that makes sense to me.
Cheers Brian and everyone else
