Sbruce, that a great group at 200 yards with an AR! This is a good post, as there are some other nice gruops as well.
That's the only group I've fired with that particular powder charge/bullet combo. I still need to chrono it and see if it's repeatable. I've also got some Benchmark loaded with same bullet that I plan on trying.
There's some great long range groups here so far, Thanks for sharing folks.
The top picture is 20 shots from an AR spacegun at 100 yards, open sights with a sling.
The middle picture is 20 shots at 200 yards using an AR service rifle, open sights with a sling. The group measures @ 2" tall by 3" wide except the 9 which was the last shot.
The bottom picture was shot with an AR service rifle at 300 yards. It is 10 shots into 3.25" fired from the prone position, open sights with a sling. Start from standing, go prone, fire 10 shots in 70 seconds including a magazine change.
DZelenka, that's good shooting for prone/sling. Congrats.
I've never practiced that position much at all.
Even with a one hole rifle, I probably couldn't shoot 1/2 that good from that position.
It just takes practice. You learn how to build a solid position. Then it is just executing the fundamentals - make sure your natural point of aim is in the center of the target, focus on the front sight, break the trigger without disturbing your sight picture.
All of those groups were shot with 77gr Sierras or Bergers, 24.1 gr RL 15 in a LC case.
