Hello , I am just getting started on reloading and am looking for anyone who has a good recipe ? I am shooting a savage 112 in 300 win mag that has some work done to it . I am a big game hunter looking to place shots out between 600 - 800 yards and am thinking something in the 165 -200 grain bullet . I live and hunt primarily in Colorado at around 7500 - 10,000 ft elevation
