when the marlin xlr come out i had read that it was made with the hornady flex round in mind and that is one of the hi end guns and it does seem to shooting well for you
i have a old 336 that was gifted to a freind it was in the rafters down in the basement of a guys grandfather rust all over it i got it tore down soaking in oil for him.
i dont think it has seen day light in 30 years that is one thing you wont have to worry about with that ss that is a nice looking gun
