I am going to try and squeeze in a range trip this weekend to test out a new scope. I am trying to get a wide variety of ammo to try and see what grain and bullet type my rifle likes. I have a CHF 16" barrel with a 1:7 twist. My question is regarding different bullets. I have some 62gr Fusion rounds, 75gr Hornady BTHP, 60gr Nosler, 68gr Hornady BTHP and assorted 55gr FMJ. How much should I expect accuracy to differ between Soft Point, FMJ and BTHP? I know POI will change mostly due to bullet weight. But what difference in group size should I see? I am more interested in finding the most accurate hunting ammo. I can not use FMJ ammo for hunting in my state. No restrictions on caliber. Recommendations and information are appreciated.
