This sounded like an errant statement, so I ran the numbers on my infinity program based on our 7mm rem mags.
Without getting into detail, the the berger 180 vld at 2950, which is easily attainable in all of our guns, hits way harder, is going faster, drifts far less, and shoots flatter than a 140 Nostler BT at 3200, also very attainable in out 7 mags. Now, if the data is to fast for the AI, just back the numbers off a hundred FPS and get exactly the same results.
Your statement seems to sugjest that the lighter bullets perform better than the heavy bullets at long range. Just wondering what you ment. I confuse easily, you know!!
