Thread: .308 Ballistics

Na that was with my 16" Rock River. Velocity should be around the 3000fps mark, somebody told me they were getting 3100fps out of an 18" tube with it.

On that same trip my mate shot a goat at about 20m with a 55gr Nosler varmint projectile, out of his 14.5" and it didn't fragment violently. It actually ran a few meters before collapsing. There was no evidence of bullet blow up, basically just performed like a soft point. I think that the 55gr Hornady soft point is just unpredictable. Sometimes it fragments, other times it pencils through. I did have one shot of it do catastrophic damage at closer range. Massive open exit wound in the neck/shoulder, arterial bleed and stuff, was pretty messy.

The 75gr BTHP (Hornady) is meant to be more reliable at killing than the 77gr Sierra's. Slightly higher BC too. I believe it is what they use in the 75gr TAP load. It is a shame you can't fit the A max's in an AR, I'd imagine they would be devastating, within reason.
