Hello , just got another mx ,and yes serial # is 91 but it is a remington and I am just in from shooting it ........ The wood is excellent but heavy .... fit is ok and I had to shim it just with two of the marlin shims from previous guns to boresight it. Well it shot good to excellent action is rough I hope it gets better , I only had time for 16 [email protected] to get it on the straight and arrow as work comes first. 2'' group ,but I ask again A question as I am concerned that my primers were hitting very low again ,is this something to be alarmed about. This goes out to all the guys with good 338 mx's can you tell me if your primers are hitting on centre or off low to the bottom ? I know I am new and it may have been posted ,but I wil continue to purchase and send them back until things are ok , ps my gun broker recognizes my # and I dont care I am sure he is getting tired of ordering and sending back and reordering marlins for me
