I have a 98 mauser in 22-250 and if I shoot in realitively rapid fire say 10-15 seconds per shot .shot #6 will show pressure signs and about 8 or 9 will just have a primer drop out . Even with mild hand loads every time with white box Win. I've never had the bolt hang up or even get whatI would call hard lift though .

I think it has to due with the mass of the bbl and the action and cooling .
If you can get the bolt all the way up use a brass or if you must a crs steel rod use the rods wieght to "drive" the case out. If the bolt won't lift just take it to a gun smith that 30-40 bucks wilbe well spent if somthing lets go .
