Tonight I noticed the closed bolt on my .243 has movement in it. I placed my fingers on the bolt and my thumb under the action on the stock and squeezed. I saw movement. A considerable amount. I didn't notice it with a snap cap chambered or on my .270 though. What gives? I know the rear baffle on the bolt head is floating for bolt head alignment. My .243 is older than my.270, since 04 did Savage change a design to tighten up the rear baffle?
