Bullet Rise/Mid Range Trajectory

can someone tell me where the "engine" is located in a bullet? I have been wondering for years now.... oh and the wings too!

Yet right. Need thrust and lift. Now if some of you Rimfire boys mention a rh twist climbing into a 3 o'clock wind, it definitely do. It just don't drop quite as far.

Bullets don't rise. We point them upward and they drop into the target.

English is my native tongue. In my experience the word "rise" means the same to most folks as it did to Mr. Webster who said this about the word "rise":

"To move from a lower position to a higher one; come or go up."

When I point the muzzle up, the bullet rises to it's apogee which is invariably above the muzzle where I shoot F-Class matches. Of course, if you're shootin' fish in a barrel, things are different.

yes there is a typical arc in bullet flight.
my 300 win mag 208 goes aprox 8 feet above line of sight(los)
at 1000 yd sight in, 105 dasher does less.

Yep, an arc around 8 feet above the muzzle is about right for normal target shooting at 1000 yards.

But take a look at shooting a target at 600 yards. My 6.5 Creedmoor only rises 25 inches above the muzzle, which is a lot less than most shooters would estimate. And it makes you think about the wind you're shooting in when you are looking at wing flags up on 20 or 25 foot tall poles.
 
yep...most people have no clue WHERE the bullet is and WHAT wind is affecting it.

i actually built a wind flag that was set for 7' above line of sight. offered it up as a mid "range flag" no one wanted to know.

The term you’re looking for is “maximum ordinate” - the peak in the bullet’s arc, which the bullet may or may not ever hit. You need a ballsistics calculator to figure it out.

While that may be true, unless the shot is fired absolutely vertical, the bullet begins to fall immediately upon clearing the barrel.

Perhaps English is not your first language. Here's what the Dictionary says: FALL 1. Move downward, typically rapidly and freely without control, from a higher to a lower level. It is quite clear that bullets don't always do this.

A bullet's path is restricted by the barrel while it's traveling down the barrel. That is obvious. As it exit the muzzle, it's path comes under the influence of the force of gravity. No argument there. But a bullet being under the influence of gravity and "falling" are not the same thing.

A bullet fired in a typical target match will rise at first because the barrel is inclined upward relative to the LOS to the target. And by "rise" i mean the conventional meaning of the word rise; i.e. the bullet is gaining altitude, going from a lower level to a higher level, getting further from the earth, etc.

The firing line is assumed to be more or less level with the target for the sake of this discussion.

At some point approaching halfway to the target, the bullet reaches it's apogee and from that point it falls. In other words, it is going from a higher level to a lower level. For the sake of this discussion we assume we're on earth and that gravity hasn't somehow reversed itself.

The concept of "falling" is really a simple one........... some would say it's as simple as falling off a log.

Thank goodness real life is not like the Internet.

Within the context of a bullet's trajectory, A bullet will "rise" from line of sight, and "fall" from line of departure. You may have the definition of the words, but it is the application of them that is confusing people.

I have never seen a bullet that didn't do this, unless it hit and stuck in something while it was up there. A bullet will always fall, unless your rifle shoots above escape velocity.
