Regarding rifle canting and bullet strike.

Now you know why I posted the popcorn emoji. Even I figured it out this time...

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.

Finally!!!! Science explains my misses.

Spk....I owe ya bigtime, buddy.

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?

The earth is flat,  so curvature doesn't exist.  Hell, everybody knows that.

Then there's Coriolis force...

LOL!!! Reminds me of when Buzz Aldrin punched that lunatic flat earth/fake moon landing idiot, Bart Sibrel. Ol' Buzz still has it!

As the old, often mis-attributed to Einstein, axiom goes, “The definition of insanity is doing the same thing over and over again and expecting different results.”

That's why I don't exercise.

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

I didn't take it well.

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.

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

Met him and had a chance to talk to him a few years back.  No one to mess with 😁
