You've got too much tension on the forearm or mag tube is what it sounds like. Barrel warms up and shots start moving. My best shooting Marlins have a bit of movement in the forearm. See if the mag tube touches the barrel anywhere. Wander on over to
www.marlinowners.com and read thru the gunsmithing section. There are threads that will walk you thru what to check and how to set your marlin up to shoot more uniform groups. Good luck! DP
