I currently shoot a 7mm rem ultra mag and was looking to purchase a 300 rem ultra mag and a 308 because so many people told me that there are more options for the 30 cal. when reloading. So my choice would be to stick with my 7mm rem ultra mag and purchase a 7mm 08 so I can reload both or go to the 30 cal.....what do you guys suggest and do any of you or have any of you used both calibers so I can hear the good, bad and ugly.
