If one is looking to see what a hunting rifle will do there's two things I'd avise. One is in the beginning reach a little deeper in to one's pocket and try as many different factory offerings as possibble. Make it cost effective maybe you have a friend who has a rifle chambered in the same round , you can split the cost while experimenting. Second keep your strings to 3 shots. In hunting situations most will be lucky to get two shoots let alone three and five would be out of the question 99.9% of the time.
Then it's practice ,practice ,practice. I've found that most rifles will shoot better than most are capable two and that if you shoot factory ammo Hornady and Federal are the two most consistent offerings on the market from box to box.
Most of my big game hunting I do is with a 7mm rem mag. in a LH Rem 700 DBM.. When I do my part the rifle delivers 1/8" center to center 3 shoot groups @ 100yards and 3/4" when I'm not and have a flyer.
