I am pretty new to rifles as I don't hunt but enjoy shooting and that is why I am asking so many questions on this forum of late. Today I traded for two additional rifles and would like to get opinions on them. The first is a used Marlin Mod 336 in 30/30. It is a 1970 vintage 100th anaver. addition. The second is a new Remington Model 7 in cal 260 Rem. I am not familiar with this round at all. Thanks for any info.
