Do Western Rite Churches use the Byzantine lectionary, or do they use an older Latin lectionary? I'm curious if Western Rite Churches hear the same readings as we do.
No, in the AWRV we do not have the same lectionary as the Byzantine Rite. The readings for the Masses according to the Liturgy of St. Gregory the Great follow the same readings as the pre-1955 Tridentine Masses. We do not use the revisions that were done to the pre-VII Masses that were done in 1961. In 1961, they got rid of many of the traditional octave seasons and got rid of many of the vigils for the Apostles' feast days, to name some examples.
The Byzantine calendar and the traditional Western liturgical calendars are set up differently. For example, during the season of Pentecost, which is from Pentecost through the last week of November, if there is no feast day during the week (a feria) the Mass readings and all the propers (introit, collect, secret, etc) are from the previous Sunday's Mass. There are no daily readings assigned like they are for daily liturgies in the Eastern rite. An exception is Lent, when the Western Rite has daily Masses and assigned readings and propers for each Mass (unless there is a feast day that outranks it).
So this is not a pre- or post-schism thing. The Byzantine rite and the Western rite have their calendars set up differently and also their lectionaries. I would imagine this would hold true if comparing Armenian rite or Coptic/Ethiopian rites with the Byzantine rite. Each has its own customs. I hope this helps.
