No Deker, it isn't only your opinion bud, it's mine too - I agree with you there!
Ian mate, for the sake of example, lets assume you go for what is (at the point of shot release) a perfect head shot, but the bunny moves just a whisker after the shot leaves the barrel. You end up wounding it, and then need a quick follow up shot as a coupe de grace . . . . . if you have a multi shot pcp - then no problems here.
But, on the other hand, if you have a single shot pcp, then you have to re-lood manually and so the unfortunate animal is suffering where not necessarilly needed, like?
