Are you picking between these two because it's a short range brush rifle. When it comes to ballistics, the .35 Rem may shed velocity and energy quicker than the .30-30, but if it's recoiling at around 20% more, then there may be more ballistic oompf at short range. On the other hand, either is plenty.

I like the .35 Remington for what it is. If it's new to you, it's not the worst thing to try out just for fun. I doubt most would notice much recoil problems. Lever gun?
