Oh dear, another one who believes the moon landings were real. We shouldn't allow this sort of conspiracy theory stuff on the forum.

Oops, done it again, I need to remember to insert emojis. That was an effort at humour.  I like me a conspiracy theory about as much as a digital prostate exam.

SO ! Let me see if I get agreement.

Shall we make the distance 250 m, because only after about that distance do we really begin to see the real curve in trajectory using common modern velocities.(Also the distance I cut my clients off at)

If I can get a 160 gr .270 bullet up to similar velocities as what I shoot a 150 gr bullet, I will not lose much any if trajectory at 250 yards.

My Quick Load packed up - I miss it.

Quote from: Ds J on Today at 12:48 PMI remember a youtube video about a feather and a ball falling in a vacuum from the same height. They touched earth at basically the same time.

Aerodynamics/wind resistance makes all the difference.

Quote from: 223 on Apr 18, 2024, 07:39 PMI size my 9mm cast bullets in a Lee .356" sizer.  They are quench hardened and powder coated.

Are you sizing first then powder coating ?

General Hunting Discussion / Rat had puppies
Last post by Treeman - Apr 18, 2024, 10:51 PM
The hunting dog had puppies, I wanted one of her, and every farm we hunted on wanted one of her if we ever went the puppy route.
 I really wanted this dog to live on through my last years and decided to allow her to breed.
This is the puppy we kept.

Quote from: BBCT on Apr 18, 2024, 08:47 PMMaybe here is a way to explain it:

Stage 1: Assume you fire a heavy bullet and a light bullet perfectly horizontally at exactly the same instant. They will drop and strike the ground at exactly the same instant in time irrespective of relative velocities or BC's. It is the same as holding both bullets in your hand and dropping them together - both will reach the ground together.

After that it gets a bit more complicated............

Stage 2: If launched at the same velocity, the bullet with the higher BC (typically, but not always the heavier one because BC is dependant on bullet shape) will travel further from origin before striking the ground because it will have a flatter trajectory. They will however still strike the ground at the same moment in time after firing.

Stage 3: Assuming both bullets are approximately same shape, the heavy bullet (typically better BC) is normally fired at a lower intial velocity than a lighter bullet so the lighter bullet starts off maintaining a flatter trajectory than the heavy one. The light (stubby, poorer BC) bullet will slow down at a faster rate and at a certain point, both will be travelling at the same velocity whereafter the heavy bullet (better BC) will overtake the light one. The bullet with the better BC (typically heavier) will maintain its velocity better.

Be aware that round nose bullets will always be heavier than then a spitzer bullet of the same length. RN bullets are normally designed specifically to get maximum weight that will stabilse in a barrel of given twist rate.

All of the above is pretty much meaningless at responsible/normal hunting distances of 200m or less because very few of us can shoot that accurately under field conditions.
*******************************
This is what i thought I knew and wanted conformation on.
If it were  not for aerodynamics, a feather a golf ball and a bullet of same weight would touch earth at same time if dropped from same height.
In shooting the faster one will travel further in same time, but the drop would be the same for the given time of travel.
