RE: 30-30 Winchester
the 30-30 makes a great gun for whitetails, i dont have any experience hnting elk but i do know your max range with a 30-30 is 200 yrds tops, the 30-30 just doesnt have enough muzzle velocity for shots past 200 yds, also your remaining energy probably wouldnt be sufficient to harvest a very large animal like an elk.
