Above is a picture of a very old box or Remington factory match ammo meant to used in the Palma matches. At the time the match was shot using the .30.06 round. Today the .308 Winchester is used with ammo firing the 155 grain palma bullet shot from 300 to 1,000 yards with iron sights, or the 556MM using 80 gr bullets.
The 80 gr bullet from a 556 is a good combo for long range shooting. I never had very good results using the 155 Palma match bullets in a 308 myself. I prefer the 175 to 185 grain bullet in 308 for shooting to 1,000 yards.
Below is another couple of boxes of factory Remington match ammo, This made up for the Army marksmanship Unit for various competitions.
