150 rds 25g JSB 700mm Impact. I clean after every shooting session. Now, before you try to figure where this lead is skinning off; Im shooting pellet on pellet @ 50 yds. Dandelion bud @ 50 & 60 yds. Steel fence posts @ 100 yds. Golf balls @127 yds.
I’m having same issue!, (.22cal. 16 & 18gr jsb’s & AA’s) the lead doesn’t necessarily bother me?, I’ve seen this before in some high quality barrels, but the accuracy is there in those barrels(clean or dirty) in this X barrel accuracy really drops off when dirty ( if u want to call it accurate! ) I’m still playing ,hopefully it will improve? if not I will contact FX USA, maybe they will want liner back for inspection and send me a new one?
FX500 smooth twist. At least 30,000 JSB Kings and have never cleaned the barrel. Less than 1/2 inch at 50 yards. What happens if you don't clean? What am I missing?
SMOOTH TWIST! I didnt have to clean impact either. Probably had 8000 before i detected poi jump. Took a little while to figure it out. Really had imbedded lead in barrel. Took some cleaning. New X barrel is going to need monitoring. At leat mine does, i dont mind the cleaning, once i figured out what was going on. The accuracy is more than worth it. to answe Sdellinger. Poi will change. Fliers will abound.
