Quick Answer
The 6.5x55 Swedish Mauser rifle is known for its versatility and accuracy across various bullet weights. In general, it performs well from 100 to 200 grain bullets, offering a good balance between expansion and penetration.
Performance with Lighter Bullets (100-120 grains)
The 6.5x55 excels with lighter bullets, particularly for hunting smaller game such as deer and wild boar. At these weights, the rifle’s muzzle velocity remains relatively high, typically around 2700-2800 ft/s. This allows for effective expansion and deep penetration, making it suitable for shots at longer ranges. However, it’s essential to choose bullets designed for hunting, such as the 107-grain Sierra GameKing, to maximize performance.
Performance with Mid-Range Bullets (140-150 grains)
For larger game like moose, the 6.5x55 performs exceptionally well with mid-range bullets. The 140-grain bullets, such as the Hornady ELD-X, offer a great balance between expansion and penetration, achieving velocities of approximately 2600-2700 ft/s. This weight range is also ideal for hunting at medium to longer ranges, making it a popular choice for Scandinavian hunters.
Performance with Heavier Bullets (170-200 grains)
While the 6.5x55 can handle heavier bullets, its performance may suffer slightly due to reduced muzzle velocity. For example, the 180-grain bullets, like the Nosler Partition, typically achieve velocities around 2400-2500 ft/s. However, these bullets are still effective for hunting larger game, particularly at closer ranges, and offer excellent expansion and penetration.
