Don't forget the lowly AA S400 (don't laugh). The ONLY person to date to score a 230 and received a Chinese Dentist Award for this achievement in our Inter Club (Rochdale v Rivi R.) and Internal 50M Bench Rest (type) competitions ( rules: 12" max-width front bipod and NO rearrest) was using a S400 beating several Daystates, Styers, LG400s etc. and that's after months of competitions.
Yes, I know it's down to the shooter but he's not repeated this feat using his 'lecy' Daystate.
