[QUOTE="milanuk, post: 512047, member: 376"] Palma is shot from the prone position, using a shooting coat, sling and glove, and a rifle normally chambered in .308 Winchester and equipped with micrometer-adjustable aperature sights. For International competition, 155gn is the weight limit (no such limit for domestic U.S. competition), and twist rates of 1-12 to 1-13" are common, as are 30" barrels. Some of that barrel length is for getting the bullet up to speed to keep it well above the speed of sound at distance, but also for increased sight radius to aid in precise aiming. The sights are often referred to as 'iron' sights, but bear about as much resemblance to the open buck-horn sights on a .30-30 as a Nightforce 12-42x NXS does to an ACOG or Aimpoint. Between adjustable aperatures in the rear (which allow you to close down the size of the hole and increase the focal length) and front sight (which allow you to adjust the 'line of white' between the black aiming bull and the front sight ring), plus the use of diopter lenses (which help with bringing both the front sight and the target into focus)... most people who say things like "Iron sites at 1,000 yards is beyond what my eyes can do!" have probably never actually taken a look thru a set of modern aperature sights. As for the bullets... they are first and fore-most target bullets, meant for poking holes in paper. This particular weight class has enjoyed a lot of scrutiny and development over the years, so they do shoot extremely well out of a lot of guns and work well for a lot of things they maybe weren't designed for.
