I have a bighorn orgin sa that I am going to get another barrel for… it’s sitting in a manners pro hunter, I have been trying to figure out what to pick, I hunt deer for the most part and the furthest shot in my area is 600 yds but I shoot steel further, 1200 sometimes. I would like to be able to take elk out to 500 ish but I would also like to be able to find decent factory ammo, let me hear what you recommend!
