I'm in the process of replacing the old crappy 1970's trim room by room in my house, and of course the drywall is almost 1/2" proud of the door jamb in the first room I'm working on. I've been researching ways on how to proceed, as my understanding is 1/2" gaps are way too big to fill with caulking.

Would love to hear from the experts on what is the "right" way and what is the "easier" way. I'd like to do a decent to good job, but I don't need perfection. Based on my research:

• I could pound the drywall to condense it, but I think that no amount of pounding is going to condense by 1/2"
• I could extend the jamb by ripping primed pine or similar, and use glue and/or 18 gauge nails to float the jamb, and then attach the trim to the jamb. If I go down this road, I'll need to buy a table saw (which is fine)
• I saw someone on YouTube use a foam backing rod and wood filler to fill the gap.

Any advice or recommendations is much appreciated, thank you!
