Winchester has changed the composition of the primer metal in the last year or so - there's reports here and there on the reloading boards about this light-strike problem.
The new ones have a slightly different color.
I loaded some of these in .45ACP for a Glock 30, which is striker fired. Had a devil of a time for awhile till I got them used up.
Now I use Federal or Remington for pistols, CCI for semi-auto rifles.
