So I am going on a dall sheep hunt in 2022 and have been planning the hunt and am planning on taking my Christensen arms summit TI 28 nosler with me. I have 200 rounds of factory ammo ready for it to be broken in, sighted in and practice and get familiar with it over the course of the next 7-8 months. During a discussion with a friend about what load and rifle I'm going to shoot he thought I was stupid to be shooting nosler e-tip 150 grain copper bullets in Alaska on sheep and that they will get sent to fast out of a 28 nosler and be unstable, and suggested I use a heavier 160-180 grain lead bullet. This now has me concerned if I made a mistake with purchasing this ammo for this rifle, for this hunt. Maybe I'm just getting in my head about it because of the hunt and it being once in a lifetime for me but what do you guys suggest and what is your advice on this rifle, round and load? Should I use a lead bullet? Is a 150 grain bullet to lite of a grain bullet for a 28 nosler? My barrel is a 1-9 twist barrel. Does anyone have this same rifle, and shoot 150 grain? Does anyone shoot 150 grain out of there 28 nosler? What's your experience?
