It just really depends on how light you want to go, how your rifle balance is and what you're willing to accept. I believe the bergara is a 700 footprint which opens you up into a huge variety of stocks. What does your stock weigh currently?
Sounds like you are standing on the edge of the rabbit hole. Keep the 300 a least for now. Decide what the target weight of the gun you are wanting. Buy an action that will be modular, I use Zermatt / Bighorn origin long actions. I can change the bolt faces to match what I'm shooting and long action makes it where I can shoot most anything. Order your barrel, pencil profile will be the lightest, but most are to small to thread for muzzle brake or suppressor. Then order a stock, trigger, and scope that keep you in the target weight. Then look at your bank account and wonder where the $5000+ went. Finally sell the bergara and order another caliber barrel for variety.I actually don't know. I believe the whole gun is 7.6 lbs. I think I should just sell or leave it in the safe. Anyone interested in buying the gun in previous picture let me know!
To me the recoil difference isn't much, but keep in mind everyone will feel the recoil differently. Creedmoor feels like shooting a light projectile 308 and the prc feels like a 270off topic a bit but...guys who have hunted with the 6.5 prc and 6.5 creedmore....is there that much difference? More recoil? Faster for prc? Ive read the stats etc but curious to first hand opinions.
