.30 Rem.

The 30 Remington, also known as the 7.62x39mm is an American-made rimmed centerfire rifle cartridge developed by Remington Arms Company in 1906 for use in their Remington Model 8 semi-automatic rifles.

The 30 Remington is a medium power round, operating at relatively low pressures which makes it suitable for use in older or weak actions such as those found in most surplus firearms. It has good accuracy potential and the flat trajectory makes it ideal for shooting out to medium range distances on target. The terminal ballistics of the cartridge are decent with soft point or hollow point bullets offering clean kills on animals up to the size of medium-sized deer depending on shot placement and conditions.

Ammunition for the 30 Remington is widely available as it's quite popular with hunters due to its relatively low cost compared to other hunting cartridges available. Most manufacturers offer several different bullet weights ranging from 85 to 110 grains, loaded with either soft point or hollow point bullets for maximum expansion within the target area.
