Don't worry Andy, I shoot my 97 much better than any of my pcp's and was always perplexed at this to say the least!
As the other guys have already commented, I came to the conclusion that shooting a springer needs much more concentration and have to keep an eye of many things simultaneously to shoot well, so when I switch to pcp, I assume that it's so much easier and take the shot for granted, resulting in a missed target.
Spring guns and pcp's are 2 different animals which have to be handled in different ways but a shot must never be taken for granted by either gun, total concentration and technique is needed for both to ensure a dropped target!
