The manual does say 100 shots.I find it depends on your loads & powder.
43 grs of SR4759 and 250 gr Hornady LOW DRAG SST'S shoot well in mine.
The gun will probably shoot 100 rounds reliably without changing the V/L but I find accuracy starts to drop off at about the 50 shot mark.
I lube the V/L and B/P with the silver brake anti-seize from Canadian Tire and have never had a problem removing the V/L or B/P...
So that's 2 cleanings per year,1 after 3 range sessions of 10 shots each and the 2nd and final after Deer Season when it's time to put the gun to bed ( all on the same V/L).
