i dont rate pellets as poor for whats left in the tin, rather than performance in my rifle. i buy good quality pellets. i would not spend hundreds of pounds on a decent quality rifle and then stuff the cheapest pellet into the breach. this does not make sense, unless of course the cheapest pellet performs well.
worst pellet for me was Daystate LI 7.9g, looked fantastic, good quality but just did not like my rifle.
i'm not perfect, but I shoot FT, reality is this is pretty much the same thing!
