there is usually quite a difference in case capacity between Winchester and Hornady, Winchester being a thinner walled case with a higher capacity.
But the best way to tell is some time on the range, shoot a couple of groups on separate targets one with Winchester brass and one with Hornady brass. Note the difference in group sizes and more importantly the difference in group center from point of aim.
If this is acceptable run with it if not cull the brass your not happy with.
