Actualy bullets fired into game tend to not go where you expect. So you have never actualy shot a animal? What kind of hunting do you plan to do? White tail deer? Well I think the 7.62X39 is not the most ideal gun for the job but it works on midsize deer out to 100 yards. And shot placement is the key. Anyway I onece shot a coyoted from behind with a 7.62 fmj, Actualy it was my last round after my friend fired 5 soft point shells(runing shot) and hit it in the leg. All that was on me was 1 fmj. Well the thing was slowly getting away and Then I loaded the shell and fired well he died right there up one end and out the other more less.
I have shot some dear with the 7.62X39 and it works all of them droped on the spot but I like the .270 because it can handle the bigest of them and out to 400-500yards at that.
