Well im sorry to say i wasnt successful getting these 39g wildmans to group in my .25 Delta wolf , liam at wildman slugs was very helpful on the whatsapp but i SIMPLY could not get these slugs to group very well at all , i tried dropping and raising the hammer dwell and raising the reg pressure , but i found some success with JSB mk2 knockouts, i managed to get them to start grouping so it now requires a bit of fine tuning.
I tried these MK2 knockouts in my .25 Redwolf ....holy poop can it group well ! , sub moa at 100 yards straight off the bat ! That rifle just shoots so many different slugs so well , it makes the delta wolf look like a glorified brick !.
