If it retains a slightly greasy/creamy texture and has remained in the lube groove(s), it should work fine as is. If it has dried out and/or come out of the groove(s), it probably won't work well.

I'm not a fan of liquid alox, but without a sizer lubricator, the liquid alox may be the only way to salvage your bullets if the original lube appears to be ineffective as described above.
