A second issue with the Hornady brass is it is often TOO LONG. They need to increase their case head diameter, and DECREASE their "trim to" length.
The cases that literally stick in the chamber (a separate issue from just the extractor missing the rim and the bolt coming back empty handed)...
...anyway, these cases that tend to stick are probably too long, if you measure them they'll be as long as 2.745" in some cases, fully .030" longer than they should be, at around 2.715" for the Savage chamber. A case that is too long can "bottom out" in the chamber and crimp the bullet like a vise--driving up pressure greatly, and yes, sticking the case in the chamber as often happens with over-pressure loads.
The Savage chamber is very tight, and that's a good thing... once you have brass that works in it, and of course the Lapua brass does work.
