Well ZAN sent me few hundred.177 slugs to try 11.2 gr .
HW100 k didn’t like them to much , low power . Next up BSA ultra , only trouble this is night time set up with pulsar N870lrf which is not that good during day time . I imagine these groups would be a lot tighter with a day scope on .
tried from 30 -65 yards and pic shows at 65 yards with night vision scope
ultra running at 11.3 with these , bit heavy at 11.2 gr in sub 12 but ZAN hopefully will be making slugs around 10 gr mark
