This is my first post on here , so hi to everyone, I’ve been the owner of a delta wolf now for at least 12 months now , and things haven’t been great , I’m from the uk so mine is sub 12 , when I got the gun my expectations were massive, I’ve owned every daystate since the mk3 and they’ve been amazingly accurate, so I was expecting the delta wolf to match or be better than the rest , how wrong I was , it grouped like a shotgun , flyers every 3 or 4 shots just terrible, honestly the worst gun I’ve ever shot and owned , I’d invested in all the PRS equipment to try and make it better, I started to question my own shooting abilities, I washed lubed weighed pellets , still joy , the strange thing was the chrono reading were amazing , a standard deviation of 0.2 over 20 shots on the info screen , and 0.1 over the fx chrono , so that led me to believe it had to be barrel , or at least how the barrel is fixed , one grub screw and the chrono connector , not good enough, so I decided to take out one of the screw’s that hold the picattiny rail on and replace it with a longer screw so that it touches the barrel and holds it in place , I now own the gun I thought I was purchasing that very long 12 months ago , I can now shoot 10 mm groups at 40 yards with relevant ease , my best is 8 mm at 40 yards , this worked for me , weather it works for every delta wolf I don’t know , this has been for a solid month now , shooting every day with qys streamline 8.48 .177 4.49 head size , there may well be tech guys on here that will say I’m screwing up my gun , but so far it’s been fantastic, considering I was not using it at all for six months because it was so bad , I’m back loving shooting again , all because of a bigger screw to hold the barrel stiff , that’s my story of the delta wolf .
