Re: 308 palma

sæll..

Síðast er ég vissi...Í alvöru international Palma Match, skjóta allir keppendur .308 Winchester (sama og 7.62x51mm NATO) hilki með Sierra 155 gr MK HPBT kúlu (eina kúlan sem var leifð).

A Palma chamber is typically one that has dimensions virtually equal to the USA SAAMI specs except for the leade or throat. Leade diameter is usually .001-inch larger in diameter than the bullet. Some 30 caliber bullets used prior to the 1992 World Championships were as small as .3070-inch and .3065-inch groove diameters were best for accuracy. Since 1992, the International Palma Committee has specificied the Sierra Bullets 155-gr. Palma bullet be the standard and these are sent to the host country for loading. Length of the chamber leade or throat is usually short enough to allow about .010-inch setback of the bullet when chambered. It's interesting that 4-groove barrels shoot these bullets more accurate than a 6-groove one.
