I had a BSA Supersport .243 25-cal & pellet sizer from TBT, topped out around 8ftlb iirc,
bought a Striker .25 when they first came out 2011/12 did a review of it, nice rifle let down by the trigger, often regret selling it, but it went to fund a Scorpion SE .25 which I've still got, superb rifle.
Also got a Rapid .25 FAC but that's a whole different level.
PS the Scorpion with 20gn FTT, a 25yd zero gives an unbroken +/- half inch PBR from 6-28yds at 11.5ftlbQuarter bore is perfectly practical.
