Here's my two cents, the 30/30 is marginal for killing big game adequately, bottom of the barrel concerning todays active carts, Yes the 30/30 may of taken the most game, due to there was very few carts to pick from in the early days that were affordable or available, the 30/30 was the most common cart. I believe there is much better tools in the shed in todays times, even my 300 Savage is about the limit for me hunting big game, If your hunting big dangerous game like brown bear/griz, you tell me you would take your 30/30 and face a 1200pd bear with a bad attitude to boot, and you just look like lunch to him. If you would you need a wakeup call, not saying a properly constructed and placed bullet would not do the job, but would you want to be on the safer side and use something with more power, I would. There is certain carts for certain category's for hunting game animals, Id rather be on closer to the Maxim power band than the minimum end myself. Dead is dead right, shot placement will always be no#1, the rest comes after. I consider the 30/30 a good deer brush gun at best. Aim small hit small. RAMbo.
