Was sighting in my rifle today 338 lapua. And after the 3rd round all my cases were stuck and so was the bolt. I had to tap the bolt up and back then use a tipton 40" rod to knock it out . Later I cleaned the chamber and scrubbed it with a bore brush then ran a wet patch of hoppes #9 then oiled the bolt. Fired one round from the magazine and it cycled flawless. Wondering if the chambers is a bit rough cause its new ir the hornady brass is just low quality. I seen brass shavings in my bolt head.
