Mike,
Clean the bore thoroughly and push pellets thru the bore, use tight end for
muzzle.  If both ends same, use original muzzle end for muzzle.  Although
bullets "precess" enough to drift to one side due to the twist, it occurs so
slowly that it could not be a factor with the ariguns we deal with.  Drift 
ue
to twist direction and rate is taken into account in long range shooting and
artilliary tables, it begins to be noticed at around 500yds and beyond, and
may
be over and inch or two at a thousand yards.  Direction of twist is of no
matter for airguns.  ld
