.243 is a very good round but its heavy on the meat damage ,good for fox and deer but theres better cal if its just for deer. 25-06 .270 6.5 308 30-06 and the 7mm which you wont get but its about the best ,the 30-06 will take any thing we can throw at it in this country a beast of a round not for first timers i think ,good if your going abroad shooting, .308 is a good round shoots well plus plenty of differant ammo to play with and plenty of rifles to buy second hand going cheep. the .270 will do the job very well , 6.5 is a very good round its the one i would go for if i did not have the 25-
