Re: Finding max load for semi-auto .308
You can also go with a 155 Match bullet.
The new Sierra Palma bullet, Berger, Hornady, Nosler or Lapua Scenar will all shoot well to 900 yds, and the Lapua is good out beyond 1000yd because it has a higher BC.
Nosler has a 175 now, for 1000 yd work, the 175 Sierra, 178 Hornady A-Max, and the 155 Lapua Scenar all have about the same BC.
Obviously the 155s can be driven faster with less pressure, so it is a popular bullet for long range.
