Lots have discussed it, but its not a real sticky thing.. some prefer the heavier bullets the 35 uses for Black Bear.. but both will do a great job on the ones east of the Mississippi .. To me there is not enough real world difference between the two .. so its all personal preference as to what you like.. some like the availabilty of the 30-30 ammo better.. the recoil is little milder I would guess. ( never shot a 35 much). I think with the new ammo from hornady the 30-30 has benefited the most from it.. but neither is a bad choice for rifle.. If I was rich I probably would have one of everything Marlin makes.. :lol:
Ballistic wise. the 30-30, 35 Rem, and 32 special are all fantastic rifles.
