The .35 Rem is kind of a bumped up 30/30. The case is not the same necked up as is the case of the .308 win to .358 win though. Factory ammo has a 150 gr and 200 gr bullet. The factory ammo is underloaded a good deal though. If you handload you can use different bullets and load them hotter, this helps the old cartridge show off its stuff. Also if you have a magazine feed rifle you can load pointed bullets which helps even more. The .35 Rem is much better than the durty/thurty and a lot easier to find brass and more bullets available than the .32 win special.
