If this was in my shop I would likely resort to my C/K oven followed by more centralized heat applied with a high wattage hot air gun.

I wouldn't be too concerned about damage to anything with that. Torches are the things to avoid here... Good luck.

4-500 degrees won't hurt anything.

I've done many. Heat and lot of it or you'll be there all day . When you smell the epoxy breaking down use your press. I have a 20 ton press bought for just that purpose. Makes a good barrel vise these days. Call me if you want to talk about it.

Are you wanting to save the barrel?

Make a sleeve to go over the threads to the shoulder then press on that. By plenty of heat I mean it will take careful application of an acetylene torch to get a mass that big to 400+ degrees.
