Link to the bucking your using? I wasn't aware of Guarder making VSR10 buckings.
I have the same problem... but with everything 0.28g bbs (washed) and up. I run a rifle with a vsr stock spring, stock hopup rubber(washed) in a shimmed TM precision hopup chamber with dangerwerx hopup arm, everything else PDI and a Tanio Koba inner barrel. What I've noticed is that at ~320ish fps and over half hop setting the bb gets clogged and falls 30m at least short. The same setup as above but with a stronger spring at ~515fps the bb gets propelled as expected (overhops actually!) but my accuracy sucks due to the Tanio Koba's temperamental nature!Hi guys
My VSR hop up arm (type b) is not functioning as it should. I got a guarder bucking today with it which is 70 degree hardness and is not washed. I have the problem of it will go to 15-20m and drop. I think the bucking is installed correctly as i have disassembled it twice. However when i adjust it over half hop on the bb's seem to get clogged in the bucking and do not fire. I am using Blaster 0.4 and guarder 0.36.
It's confusing to me and i am slightly annoyed it doesn't work.
