I have an 338 Marlin. Bought new Jan. 09..... 2008 serial..... anyways, Made an elk trip last season (2011) was not sure if was going to be able to tuff it out (motorcycle wreak)..... Had two guys wound their elk with those large mags....... I had to track both down with my " too damn small of a gun to shoot elk.... You need a buy a real gun"...... tracked first one about 3/4 mile before got finishing shot....... Second, tracked it over 1.1/2 miles before got shot at it......... What got me though was the wound channel of the 338 compared against the 300 whiz bang mags.......... Like the 338 so far................
