This can be a problem with the monsters 300 wby, rum, 338 or 375 h and h. Cost of ammo is another concern with practicing with the monsters. If you get a good 30-06, you can shot all day and still have a very versitile gun. A 30-06 will drop any animal you can find in America.

270 is a great calib. as well. Between the 308, 30-06, and 270 there is little difference. If you reload you can do a little more with the 30-06. I own them all, and they all work great and get the job done. If you will not be shooting over 250 yrds, there is not need for an ultra mag. I have a ultra mag, not because ill ever need it, Im simply addicted to big guns. (no jokes about compensation) Any of the above mentioned calib. can reach deer out and touch any deer at any ethical distance.
