Meh, what's that guy ^ know about long-distance shooting . . . .

I know of some folks that shoot their Palma rifles (.308 target rifle, prone with a sling, iron aperture sights) out to 2000+ yards. It's a silly sport and they acknowledge that. The targets they shoot are 25' x 25' or greater in size and usually metallic with a fresh coat of white paint. They shoot at them for a while, while a guy hiding behind a berm uses a stick to point at their hits for them. After a bit of shooting he scoots out and paints over the hits and they begin again.

That same group of folks once told me that of all the .308 projectiles in existence, the SMK 175 grain had the most interesting ability to re-stabilize after passing through destabilization (happens when moving from super to sub-sonic). I don't know of this phenomena being documented anywhere, it was given to me by word of mouth, but it came from reputable sources.

The obvious bummer is that while the bullet has destabilized, it can make some pretty egregious course changes. That being said, they all swore by the SMK 175 grain when shooting a .308 Win at silly-stupid-no-reason-but-for-fun-distances.
Best,

Okay I finally had a chance to do some long-range shooting. Previously my longest was 200 yards. I went to Eastern Washington, and shot at 380 yards, 700 yards, and 800 yards.

I could only put a target at 380 yards, 8" gong. Hit it 100% of the time.

At 700 yards and 800 yards I was just shooting at the ground, rocks, bushes, spots between rocks etc. My ballistics calculator was spot on, and my shots dropped right where I expected them to go. Without a target, and just looking at puffs of dirt, it's hard to tell whether I was Minute-of-Angle, Minute-of-Deer, Minute-of-Elk, or Minute-of-Elephant.

Next up, I need to go back with real targets so I can actually see my results. I also need a range finder that works beyond 860 yards.
