Did this project. Here is my take. I had to buy a new firing pin for the new bolt head as I had an older model Savage 10 I did this with. Had a large pin. PTG uses small pin if I have my details straight. I bought a new ground recoil lug and nut as well. I ordered my barrel from Shilen. Got a 24" Select Match Barrel. Takes time because they air gauge them so they have to wait on something that gauges correctly. Barrel does 1/2"-3/4" MOA with several factory loads. Feeding is not the greatest I feel. I even took the time to try and polish the ramp. Mine sits in an Oryx chassis. I'll post pics if I have any on my phone. Otherwise it will have to wait till most likely this weekend.
Worst best idea and project I have ever done. Only did it because I had the action already with a barrel that didn't shoot well. Money I spent could have gone better towards a custom action. Spent A LOT of time polishing everything and working things in with valve grinding compound and cratex tips so it felt more custom and less Savage. (If you do decide to go this route, remember to take your time, go slow, not something you rush. Plenty of info on how to lap bolt lugs, polish feed ramps, etc.) Got a longer bolt handle with knob, tracked down a bolt lift kit, messed with the firing pin spring tension, checked firing pin protrusion. With rifle properly greased and lubed, she is between a Christensen and a Curtis as far as ease of bolt lift and smoothness.
Would I do it again. Honestly, no idea. I did learn a lot though. I also really love the rifle, but that could be sunk cost fallacy. At the end of the day, no matter what you do to it, it's still a Savage. It's mine though, and she hammers.
