What speed are you shooting? Normally Winchesters have a max of .007″ headspace and don’t push primers out more than about .001″. Hot loads do some weird things.
All were various factory 150 grain ammo, no reloads.

My 1894 Takedown 30-03 made in 1913 is exhibiting excessive headspace. Went to the range yesterday and noticed the primers backing out in these measurements: 0.0175, 0.011, 0.0145, 0.013 and 0.0155. Would you consider this excessive? I am thinking about replacing the locking bolt with an oversize one. Any recommendations on how much oversize? TIA.
That’s quite a range of variation. If it were me, I would look at .015″ oversize if it’s an option. Your casings will probably suffer case head separations if reloaded as that is quite a “stretch” for brass if indeed the headspace is that excessive.
