Absolutely nothing wrong with the 30-30! It has killed more game in north America, than any other rifle! I believe it was the first smokeless rifle cartridge. It can take any north American game animal, including a Griz, with proper round, 170 grain, and proper shot placement. Not my first choice, but it will kill one. But it is a great hunting round, and out to around 250 yd.s it is very effective! Use it with pride! It is a great rifle round, especially for brush. I am currently looking to find a good used 30-30 rifle, for brush hunting. I have a Marlin 45-70, but would still like to get a 30-30.
