Thread: 6.5mm questions....

A 100-150fps difference in MV won't make a huge difference in range I wouldn't have thought, would have to check the energy numbers. A very accurate and low recoiling 6.5 makes for a highly effective 500-600m+ pest goat controller, doesn't need to be fast.

I believe it's the combinations of bullet-length,plus rpm's (8-twist), and BC/SD, that make the 6.5's so efficient at the lower FPS. It appears to be one of the few calibers that gets everything right. With the 6.5x55, it was second only to 9mm parabellum, in having the highest no. of ballistics-experts, involved in its development.
