its good fun testing pellets and doing crono strings, it gives you confidence in what your using!
and whats good for one gun may not be good for another of the same make and barrel.
the last pcp with a 177 walther barrel liked rws super field and the tx spat them out all over the place, same barrel apparently... but is spot on with aa diabolo's.
done loads of testing with a hw100 in 22, aa diabolos and superdomes are the only ones i can get to group!
what mark said to me was spot on, if i put anything else down the barrel its a pull through cos nothing will group again!
end of pellet test
