    Just for your notes, at 700 yards, the earth curves ~ 1_3/16" (1.181102") but, of course, the pdog terrain will vary more than that. But ya never know, could be useful. 😜
    Funny.....I've shot more than a handfull of 700+ yard pdogs, and never once took the curvature of the Earth into account.

    So the curvature of the earth is constant as in theory, there’s no flat spots. 

    So does the fact that I shoot East to West as apposed to North to South. Effect the bullet path congruent to the curvature/rotation?

    Here's home video of when my dad first told me the earth wasn't flat. 😂

    Depends on what side of the equator your on ,as to if you sight one east to west or west to east.😈

    I find if I hold a rifle upside down and backwards the results are not good, especially for anyone standing behind me.

    A few years back I was hunting deer in a creek bed...sitting in some brush against an old fence post...I had a sizeable doe wander in from behind me from my left at about 50 yards out...there was no moving around to get a good shot...but I found that by leaning forward and canting my AR 90 degrees to the right, I had a perfect set-up...The rifle was zeroed dead on at 100 yards...impact was slightly right and a bit high from my POA...the doe ran about 25 yards before piling up....

    We practice “side prone” (laying the rifle on its left and right side while shooting) out to 200-300 yards. 

    A comp I attended once had a 400 yard side prone shot.

    That sounds like a fun day at the range. 👍

    There is a drift effect at extreme range caused by rifling but I don't know how much it means in practical terms.
    Concealed carry is for protection, open carry is for attention.

    Spindrift.  About .5 MOA at 1000 yards.  That's for a relatively fast spin.
