I am going to build some loads for my father-in-law's 7MM STW, I am thinking about starting with some 140 accubonds and 140 Nosler balistic tips. Have any of you had much experience with this caliber? Should I skip the lighter bullets and go to the 165+ grain class? He did not draw an elk tag this year, and if he were to shoot it this year for hunting, it would only be deer. Any advice is appreciated, I have no experience with this gun or caliber.
