I'm not sure if you fixed this yet, but I had the same problem with my short action 6.5 creedmoor. What I did is start by ordering a set of pin gages from .699 up to around .703. You can get them on Amazon individually:

I'm not sure what the standard raceway diameter is for your gun, but once you figure that out, order pin gages that are a bit smaller and a bit bigger than that. Next I ordered a custom Savage short action bolt body from Pacific Tool & Gauge:

Basically what you do is take your pin gages and find the one with the least slop by running them into the chamber from the back with the bolt removed. I found that .701 was a perfect fit. I originally followed the company's recommendations and ordered a bolt by subtracting .002 from the measured size. That did NOT work for me. I ended up with a bolt that was no better than the factory one. So, I ordered a second bolt and told them to make it as close as possible to the size I measured with the pin gages (.701"). It fits perfect and the slop is totally gone and it doesn't hang up. Also, don't be drawn in by the fancy fluting. It looks cool, but it will not help your problem. Hopefully this works for you.
