Went to my first long range shooting comp today…

Think about this.
If the bullet sees wind at the shooter area and gets blown off course early in it's travel it will drift further off point of aim vs just seeing wind 1/2 way down the range.

Most trajectory calculators assume wind is constant from one direction.

Kinda!!!!!!! If bullet near shooter at higher velocity drifts X vs bullet at slow velocity at far target drifts X then NO it may not be further off point of aim.

Friend of mine did some experimenting with winds at his range and blocked the first few yards of the wind by the shooter and shot at the 100 yard target.
Then moved the few yards of wind block down range and shot at same spot and found the first few yards of wind near the muzzle made a huge difference in wind drift.

He was all excited to show me.
Try it before you give me X VS X

LOL you went from commenting on long range shooting back to 100 yd shooting and still dont know your ABC's of X vs X's etc.

His comparison with a bullet with less than half the BC of the other to justify his article needs some ABC's too

308 150 gr @ 3000fps
223 75 gr@ 3000fps

I am not comparing different bullets at all. I am talking same bullet same velocity same path just where wind is at.
10 mph wind near shooter will tilt the bullet off path and move POI farther.
Than 10 mph wind at 50 yards down range and no wind at shooter.

No math needed for that just common sense.

I tried shooting my Remington 700P in 308 Win out to 1k. 175gr Sierra MK. I to was struggling. An old timer bench rest shooter told me to dump the 308. Evidently between 900 to 1000yds the bullet drops subsonic and weird wobble/oscillation occurs. I dropped down to the Sierra 155gr Palmas and pushed them harder. It helped but was no cure unless I wanted to change to a 30” barrel. I shifted completely to a Remington 700P in 7mm Remington Magnum (Secret Service choice back then). Problem solved. Now Im shooting a 6.5mm Creedmoor.
