The mini 30 and the mini 14 are reliable and nice looking weapons. Their accuracy is not that good. If your target is within 100 yards they will do fine. If over 100 consider another weapon. M1A, AR-10, AR-15, and if you are thinking of a bolt gun there are many that will do the job. The Remington 700 and 710 series available in many different calibers will do what you want done.
I have to disagree with you on this. I make 300 yard shots with my Mini 14 and I don't miss.
