F-class .308 factory ammo question?
 
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?:confused: I thought the conventional wisdom was that the heavier bullet performed best at longer ranges. 67"?

You need the weight to help buck the wind.

The 155gr your going to need a 32" barrel as they are the palma match. they are made just for palma shooting and I believe the 155 SKM Palma is the bullet used for all Palma matches show in the USA. As the country holding the comp has to supply the ammo.
