[QUOTE="marksman1941, post: 3066146, member: 68542"] The 7’s will carry velocity better at that range. Energy is less important; matching your bullet velocity threshold with your impact velocity matters more. Most (huge disclaimer on the “most”) bullets have a lower expansion window between 1800-2000fps. Trying to keep comparisons consistent, I used the heaviest factory Hornady load shooting eldx bullets in the following data. A 28 nosler shooting 162gr eldx and a 7prc shooting 175gr eldx (factory ammo) both reach 1,000 yards with between 1250-1300 ftlbs of energy, and velocity over 1800fps (so likely decent bullet expansion). A 300 win with 200gr eldx hits 1000 yards at 1600fps with 1150ft lbs of energy. A 300prc shooting 212gr eldx hits 1000 at 1680fps with 1340ft lbs of energy. A 300rum or similar launching longer heavier bullets that can match the BC of the 7’s is where you’re going to start seeing the .30 outpacing the 7, but the smaller 30’s slow down too fast for most bullets at 1000. Of course a person can find specific ammo within each caliber that will perform better or worse, but this is speaking in generalities . [/QUOTE]
