Yes, the OP's GSR is probably one of the earlier ones. The first one I had not long after they came out had a binding bolt as well.
When retracted, you could move the bolt sideways a good inch. It was getting better with use and liberal lube, but I did a move to a different place, and sold some things, the GSR being one of them.
Supposedly, Ruger listened to complaints, and I'm sure were tired of getting them back to "remedy" for the customer. So they changed the stainless specs on the bolt, and tightened up the bolt raceway tolerance.
The later ones are reported to be better, and the one I now have cycles smoothly, for a Ruger anyway.
You do have to remember, when working the action to smartly run the bolt to the rear if you want the empty to eject clear. If you baby it while pulling the bolt back, the spent brass will be laying there, loose from the bolt head, but on top on the next loaded round, so you have to tilt the gun to the side and flick off the offending empty so you can feed the next round.
I never have that problem with my M700 or Savage, but have to remind myself when going back to shooting the GSR that the bolt needs to be run hard for positive ejection. The ad copy for the GSR on Ruger's website says: "Non rotating Mauser type control round feed is the most positive case extraction system ever invented, and features a fixed blade type ejector that positively ejects the empty cases as the bolt is moved fully rearward".

Well, all bolt actions require that you move the bolt fully rearward, but on the GSR (the two I've had anyway) you really need to get some excess velocity so you fully run all the way back, almost like a little snap at the end.
Is guess that was a good thing, when I was working up loads, that I could open the bolt gentler and pick the brass off the top of the magazine to put back in the ammo container.
And yes I save all my brass, even when working the bolt fast when shooting steel, and if I can find them, when hunting. I bought 500 rounds of new Lake City .308 brass, ( sold as Federal American Eagle 7.62 x 51 unprimed brass) and mostly load the 168 grain Hornady A-Max for my general purpose load.
These short, medium weight, good hammer forged barrels on the GSR can produce some really great groups with the right loads.
I sure enjoy my GSR.
