Not if you understand physics. A 170 gr 30-30 bullet will easily out penetrate a 200 gr 35 caliber bullet.

The original comment had nothing to do with penetration which is hardly the issue with either cartridge. Both will fully penetrate a deer. Hell you can shoot through Alabama deer with a 22 magnum. Traumatic tissue damage kills. And there is no way in hell that a 200 grain 35 caliber bullet traveling at the same speed as a 170 grain 30 caliber bullet is going to do less damage. Which is the claim I responded to. Want to argue that the difference is negligible? Fine. But to claim it will do less damage is just ignorant.
