Have been told many times a 30-30 is only good for 100 yards. Well on a hunting trip a few years ago Kirk, known here as KP and his son shot two nice trophy Caribou with a 30-30. These were not small animals either. Here is the story from Kirk's writing.
( The plan wasn't to shoot my bull with a 30-30. We had two double shovel bulls at 130 yards, two tags in our pockets, so we let the lead fly. The reason we only had the 30-30 with us was because I left my 300 WM next to a tree to make the final move for the shot. Well that turned into 10 more yards, then 10 more, then 10 more, etc... Now we were only 130 yards from a nice bull and the fog was lifting fast. Kyle pulled the trigger, dropped his bull and the other monster jumped up from his bedding area. That one was less than 150 yards, so I grabbed Kyle's rifle and put him down too.
Marlin 336 in 30-30 Win + Nikon 2-7 X 32 + Hornady Leverlution 160 grains bullets = 2 dead caribou bulls
BTW, we recovered two bullets and the weight retention was excellent. I'll try to post pictures of those later. I felt confident that the gun and bullet would do good out to 200 yards, but limited ourselves to 150 yards.)
