Erik, german guns have real good records, could be a Beeman or a Weirhuck or a Diana (RWS),........ definatly pellets make a huge difference with my .177, .....7.4gr pellets where horrible, 9.6gr better, than I tryed 10.5gr hollopoints and are awsome.
on my .22 I shoot 14.3gr hollopoints and they are good, but I'm sure if I whent up in weight a bit it probably be better.
Airguns need very little cleaning, sorry Mike but a brass brush is to much, the softer steel of the airguns need a Nylon brush, RWS has a nice kit for sale with instruction how to care foe a springer
.....HO well we are under a Tsunami watch so I have to start evacuations prosedures,...see ya later
