Re. AA Pro Sport I was considering trying JSB Exact Express Diabolo 7.87gr, has anyone tried these either with a PS or TX? If so opinions please. I've only used .177 4.52 AA Field Diabolo 8.4 with my PS up to now with excellent results but have been wondering how the lighter Exacts would fare? I'll probably buy a tin and see how they group but would be good to see what others have to say. Thank's.
