Newbie question. I'd like to restrict the question to 1000 yard factory match load performance. I used JBM Ballistics online calculator to compare a 155 gr Palma Matchking vs 175 gr Matchking. Seemed like no contest. The lighter bullet won. faster at 0,500 and 1000 and 67" less bullet drop at 1000. Am I missing something? I thought the conventional wisdom was that the heavier bullet performed best at longer ranges. 67"?
