I would be very surprised if they are better than round nosed pellets such as those manufactured by JSB & QYS at 25 yds
Myself and all of the benchrest shooters that I know have found that wadcutters are great at 10 metres but cannot match the Exact/Express pellets of JSB or the heavy streamlined pellets made by QYS at 25 yds.
Quite a number of benchrest shooters can regularly hit 250 - 16+x’s at 25 yds with JSB & Qys pellets, but I have never seen a 250 shot with wadcutters.
However give them a try you never know.
