I never hunted with it but rather built an across the course rifle around the Sierra 140gr HPBT Matchking 20 years ago. 31" very heavy stainless barrel with 1-7.5" twist launched the 140 at 3150 and the 155 at 3050 and if you did your part they stayed sub-minute at 1000 yards. Powder was 65 grains AA-8700 and I put close to 9000 rounds through it over 3 years with no loss of velocity or accuracy. Granted it was a 15.5 pound match rifle not a hunting rifle. Slow powder, long barrel and long heavy bullets will allow you to reach way out there accurately.
