The BAR is not a typical action used for long range shooting, not at least if you care that you hit what your shooting at.
Thats a bullshit statement! I got a BAR 7MM and its a tackdriver! It's not made to shoot 300+ yards it's a hunting rifle! not a target rifle. I shoots very well for a auto. If you want a auto to target shoot with go with a AR10 My BAR is good up to 300 yards easy. It's a older model I got a Leupold mk3 on it. Nice rig just a little heavy.
Sorry guys but the origional post said long range targets. That would be something well beyond 300 yds. Suddenly you develope a need for heavy bullets, which the BAR might not stabilize well. Out at 400+ yds, the world changes. If you have one that shoots well at long range targets, count yourself lucky. Give some 160gr match bullets a try and see how you do with them at 500yds.
Understanding wind currents and thermals in hilly, broken terrain can often be incredibly frustrating. I've found that collecting and storing milkweed seed pods during the late summer has made me a better hunter in the bluff country that I hunt. These little feather like seed dispersers will float on the lightest of air currents and will show you what the wind is not only doing right at you're location but more importantly down range. I like to use the off season to float them...
