This statement was made recently while shooting 22lr at 200 yards, which is super fun,educational, and quite challenging. I am not a long range shooter. The longest I have ever shot at was 500 yards,and that with a 45-70 and black powder. So, I don't know what it's like to shoot 308 Winchester at 800 yards. I can see how the challenges would be somewhat similar, but the statement was made with authority. The chap who said it is by no means a blowhard. He's a confident, capable shooter. I asked if this was based on a formula of some kind, but he said "they have roughly the same ballistic challenges". But I can't see it. Wind must be exponentially harder to read and understand. Muzzle velocities are vastly different. Figuratively, I could accept it, but even assuming properly scaled targets, 800 yards is so very much farther. Just the difference in sight picture alone must be huge. So, what's the verdict: figuratively valid if factually incorrect, or utter codswallop?
