I agree with the other responses. It does seem daystate has some barrel quality issues which is completely sad given what they cost. I think this can get into people’s heads and make them immediately think they have a bad barrel.  I have two of them, a .25 DW and a .30.   I have gone back and forth thinking my .25 especially was a little funky.  However one time I found the picatiny scope riser rail (it’s a delta converted to an alpha ) was loose and the scope ring base screws had also loosened.  Whew I was relieved.  Also conditions are a bigger factor with these guns it seems to me.  To get a really good read make sure everything is tight and find a dead calm day and shoot then.  Both of mine flat out shoot in nice conditions.  As good as anything I own so I know the barrels are good.  However, I swear I’m crazy or something but I’m convinced that projectiles out of these daystate barrels are more effected by the wind than say my FX soda straws are.  Seems crazy but I am becoming convinced.  The fx liners get a lot of flack but man they shoot accurately more consistently often.  The daystate will do it just seems not quite as often and this is mainly the .25.  I know it’s super weird. At least doing it in that manner can help you determine if it is the barrel by eliminating as many other variables as possible.  Not saying that it couldn’t be the barrel.  It might very well be.  Just read all the threads on the black wolf. People are seemingly having to work pretty hard to get many of them to even shoot pellets well.  Pretty mind boggling.
