RE: Spit patch
Several, I have never had a rifle that shot that far off on the POI he must not be cleaning it properly before he loads that could cause the POI change.My POI is usually two inches high at 100yds with a completely clean barrel on an inline and less on PRB with 6 inlines acting close to the same and having built a quite a few PRB rifles which acted similar to each other I am going to tell you that the products you use and the way you use them and the way you sight in and check the sight setting for hunting controls a lot of that particular problem.
