I have some brass .303 Brit ammo. It is in bandoleers and stripper clips. It appears to be boxer primed. The stamping on the case base is HXP 75. I assumed that because it was boxer primed it is non-corrosive. Is this the case?

  HXP is Greek, but I don't know if one can tell if these mil-surp rounds are always non-corrosive.
  
  (Sometimes you'll see "mildly corrosive or semi-corrosive" IMO those are "corrosive" and should be treated as such.)
  
  Maybe someone with experience with these exact rounds can chime in, my .303's are all cordite-powered rounds from WWII that I treat as corrosive when I clean.

  Just like HXP 30-06 is non-corrosive, so is the .303... so I'm told.
  
  It is indeed boxer primed and reloads well.

  I believe it's non-corrosive. That's what it has always been represented to me as, and I've shot quite a bit of it without any problems.
  
  Some of it was marked 'Mk VII Z'. The MK VII bullet was one of the most effective combat bullets, and the design remains widely copied. The 'Z' suffix indicates a cooler-burning powder, which was used primarily in machine guns.

  I would like to thank all of you for the information you posted. I really appreciate your efforts.
  
  I purchased the ammo years ago & did not mark it properly for future reference.
  
  Again,
  
  Thank you
