Sorry not irrelevant. When the bullet accelerates there is a force; F=MA.
This force causes recoil, heat, barrel whip… all of which are relevant.
Sorry, but that force doesn't cause those things. Momentum is responsible for recoil. Different equation all together. That one is f=Δp/t. The heat comes from the energy of a chemical reaction or friction, not from F=MA. Barrel whip also does not come from F=MA. Barrel whip comes from the explosion of the powder, very much the same way that striking a pipe with a tuning fork causes a vibration in the pipe.
It's actually extremely complicated, but one thing that has nothing to do with it, directly, is acceleration.
Not totally irrelevant, because it gives you a better understanding of the forces the bullet is undergoing.
It is totally irrelevant to whether or not a bull barrel is more accurate. Totally. The bullet undergoes massive acceleration, much higher than most people would expect, but it's acceleration has *zero* to do with what type of barrel is more accurate. (Incidentally, a very fast bullet can experience over 300,000 Gs)
So this has never crossed your mind before? Try thinking out of the box once in awhile. This is certainly relevant, it takes time for the bullet to clear the crown and a lot of stuff happens during this time interval, you have barrel whip going on, your barrel is already in recoil, the bullet is rotating at about 35000 rpm causing a torgue. The top shooters try to time their bullets to exit the muzzle when these factors are minimal.
The top shooters do not time the
tips exit and no one else does either. No one cares when the TIP exits. The body is still in contact with the barrel.
No one cares about the tip. I never said that loads aren't tweaked for bullet exit. In fact, I have many times pointed folks to
Dan Newberry's OCW load development technique, which I first learned about from UncleNick.
That technique (and all the others) have *zero* to do with when the
tip of the bullet exits the barrel.
You are not grasping the physics here. The bullet and bore/muzzle are NOT in full contact. A force is applied to the tail of the bullet which is not even close to the bullets center of gravity, this causes a torque on the bullet and can cause your bullet to key hole on paper. I bought some 357 magnum reloads from a gun shop and they key hole at 15 feet due to severe recoil. Other ammunition shoots great.
You sir, are the one who does not understand what's happening. Bullets keyhole because they do not have sufficient rpm to stabilize them against aerodynamic forces. It has nothing to do, *NOTHING*, with the barrel "slapping" the bullet. They don't keyhole due to recoil either.
Its obvious you do not know the meaning of the word premise. A premise is a statement that is assumed to be true. A question can not be a premise. “Are Bull Barrels More Accurate” is a question. Perhaps the omission of the question mark confused you.
The title of the thread is a question... your treatise is a PREMISE... a proposition supporting or helping to support a conclusion. The ending statement "if you are considering pushing the accuracy envelope, consider the bull barrel." is a CONCLUSION and/or suggestion based on the conclusions that we're supposed to arrive at based on your PREMISE.
Your premise (all of them) are either faulty or irrelevant.
