30-30 at one time was considered to be a very powerful cartridge suitable for pretty much anything in NA. That being said, the cartridge has some limits, just as every other cartridge dose. While a 200 yard shot is doable, its not the smartest thing to do. I was not there nor Have I read the artical mentioned. 30-30's took truck loads of elk moose deer sheep and what have you over the years. I had a Marlin 336 so chambered and it was fine, killed a lot of game with it, but I found I was better able to place bullets better when shooting under 150 yards, 125 was my limit. Peep sights and I wore glasses at the time. With a scope maybe a few yards more, I don't know I never put a scope on any of the lever action rifles I owned or played with, I liked the light flat easy carry lines the Marlin had, and puting a scope on it would defeat that purpose. The 170 gr Bullets that are loaded in the 30-30 do way more that what paper says they should.
