I have only ever used JSB 4.52's. A couple of months ago I began to get a lot of flyers, so sent it off for a service. I have purchased a new scope because I thought that I may be getting parallex error but it made no difference. Last night I changed scopes again, rezeroed at 35yds and it sort of grouped about 8 shots, then it goes off. I even asked someone else to try incase it was me, but the the pellets were hitting HIGH at 40 yds...with a 35yd zero!
I don't like going to the dentist
