rewmen, your Paladin needs
good closing springs to help swing
the breechblock closed. If the
springs wear out, you’ve got a much
tougher job closing the breechblock.
A lot of crewmen keep the springs
under full tension. The breechblock
closes firmly, but the constant
pressure wears on the springs and
leads to early failure. It also closes
with enough force to damage the
breechblock detent plunger and stop
surface.

enough pre-load tension to the
springs to securely close the breech-
block at the loading elevation (less

tension.
than 300 mils). Most times, that means
adjusting the springs to half-tension.
Just push in the plunger and rotate the
spring adjuster clockwise to release the
tension.
