Hatsan Bull boss........on the bench

[gendoc]

just picked up a slightly used BB for cheap !!

i have over 20 different projectiles being mostly pellets and a few slug offers.

this thing dont like anything i've thrown at it.
even the forgiven Jsb pellets.

changed scopes 3 times to verify its not an optic prollum !!
removed the baffle's with no improvement.

the power is there, 965fps with the 18.1gr jsb.
even tried turning it down,,,,,,no different !

factory scope rail has been tightend to spec.

even verified the available pressure.

i think i have come to the conclusion
that i have lost the second hand barrel lottery !!!

maybe thats why it was cheap !!!!

Give the barrel a good polish before you give up on it. There are a lot of threads on agn about barrel polishing if you need any pointers

jsb 18.1

now i have to figure out why the mag sometimes don't rotate
when cocking........any idea's ??
i've tried 3 different mags, and all do it.
