Perfection is unattainable, but the fewer gross imperfections the simpler the task at the reloading bench, which is where accuracy originates. The key is learning what some of these things, such as 'perfectly fitting brass" for example, truly are.
When I was trained to make ultra precision bearing assemblies, I learned that "Accuracy starts in the parts" ie. you have to have a precision unit from the ground up. If your barrel is slightly out of straight, and your chamber was reamed slightly crooked, and your boolits are pretty close to being right, and your........fill in the blank, I think that the further you are from perfection, the speed that you can shoot with a soft boolit degrades exponentially. No, it degrades in a linear fashion to about 120-140K rpm.
It's just like the theory that glass is one of the strongest substances on earth, because it needs a flaw to start a crack. Theoretically, if there are no flaws, then there is no place for a crack to start, and it wont crack, no matter how much pressure you put on it. Sort of....
I look at HS cast lead boolits in a similar way. I have no proof to back this theory up whatsoever, but I am experimenting, and hoping I can understand what I cannot see. Experimentation, guided by the right person, will help you understand. Lot of meaning to that word.
I have studied the rifle barrel very closely, and I can see definite flaws in all but the best rifled barrels, and factory barrels and chambers are a joke. It doesn't surprise me that most folks with factory rifles are unable to achieve any better than 1800FPS when they slam their boolits sideways into a warped hole, which sizes the boolit down as it is rolled against the wall of the barrel as it traverses chamber to crown. Some people with factory rifles and even worn-out military rifles can do much better than that, it's all in that understanding thing. If you've learned enough or at least read and listened enough to say the things you say, you should also realize that even a perfect rifle is useless without the knowledge to make it shoot, the same knowledge required to make any rifle shoot.
Anybody know if I'm on the right track, or am I majoring in the minors here?
