			Like so many other things, rigorous barrel break-in procedures were copied from competitive shooters - and have little or no usage in field guns.   
 
A Winchester M-94 doesn't need barrel break-in.  The ONLY benefit that MIGHT come out of it would be marginally less fouling and easier cleaning.  Repeat "marginally."   
 
A 94 isn't inherently accurate enough to demonstarte any improvement that break-in might show.  Nor does it operate at high enough pressure or velocity to foul badly. 
 
So it'd be as pointless as downdraft wings on a moped.
