open,  push  the  cartridge  stop  button, 
making  sure  your  fingers  are  clear  of  the 
ejection  port. 
Push the  “safety”  from  left to  right  or  to 
the  “on  safe”  position.  The  red band  indicating that the  B
-80  is  ready to  fire 
should not show. 
Insert  cartridge  of  the  proper  gauge 
through  the  loading  port  at  the  bottom  of 
the  receiver  up  into  the  magazine  as 
shown in Figure  12.  Make sure the 
cartridge  is  pushed  past  the  cartridge  stop  and  that  the...

Pull  the  operating  handle  all  the  way  to  the  rear 
and  eject  the  chambered  cartridge  and  lower  the 
bolt on the empty chamber.  NOTE:  It  is not  necessary  or  recommended  that  the  remaining 
cartridges  be  cycled  through  the  action.  That 
would  necessitate  depressing  the  carrier  release 
after  each  cartridge  is  ejected.  It  is  easier  and 
safer  to  invert your  B
-80,  insert your  index 
finger  into  the  loading  port  and  while  pushing 
slightly  on  the...

separately  from  the  gun  beyond  the  reach  of 
children. 
To change loads in your  B
-80,  simply eject the 
chambered  cartridge  by  pulling  the  operating 
handle  all  the  way  to  the  rear.  Insert  the  desired 
cartridge  (such  as  a  goose  load)  of  the  same 
gauge  through  the  ejection  port  into  the  chamber. 
CAUTION: Repeated cycling of the bolt’s 
operating  handle  alone  is  not  assurance  that  the 
B
-80  is unloaded.  There still  may be cartridges  in 
the magazine....

pronounced  in  the  constriction  area  of  the 
choke  and just  forward  of  the  chamber,  are 
caused  by leading. 
A  normal  amount  of  leading  can  be  expected  with  today’s  high velocity loads 
and  improved  wads  but this  is  not serious. If  leading should become  heavy,  it  can  be 
removed  with  a brass  bore  brush.  Spray 
the  bore  or  the  bore  brush  with  a  good 
powder  solvent,  and  scrub  the  bore  until 
leading is removed.  To prevent brass 
bristles  from  breaking...

making sure  to  wipe  gun  clean  of all  finger 
marks. 
The  wood  surfaces  can  also  be  wiped  with 
Browning  Gun  Oil  or  they  can  be  polished 
with  any  quality  furniture  wax  (but  not 
both). 
Once  a year,  or after  1000 shots,  it is advisable  to  soak  the  gas  piston  in  solvent  and  scrub  it 
with  a  brass
-wire  brush  to  remove  accumulated 
deposits.  The  gas  cylinder  and  barrel  guide 
should  also  be  thoroughly  cleaned  and  wiped 
dry.  Do not oil.  If at any...

it  can  be  grasped  and  pulled  free  by  hand.

button  flush  with  the  receiver  and  lift  the 
trigger  housing  forward,  up,  and  out  of  the

REPLACING  THE  TRIGGER  HOUSING— 
With  the  bolt  closed,  and  the  trigger  housing 
hammer  cocked,  and  the  safety  in  the  “on  safe” 
position, insert the mainspring support into position 
by  mating  the  projection  at  the  rear  of  the  trigger assembly into the recess inside the receiver. 
(See  Figure  17.)...
