And another thing...
I ain't trying to pick on you, you were just the first one brave enough to try and answer any of my questions
.
But humor me for a minute and follow along.
Let's say, we do have inconsistent hardness and variation in neck tension. Just terrible inconsistent! Okay, so we anneal, now we have wonderfully uniform consistency of hardness and neck tension. Awesome!
How much difference - real MEASURABLE difference - as measured in group size, does anyone think that could make? .050 MOA? More, less?
Be very interested in what the proponents of the accuracy benefit of annealing think? I really would. Put a number on it. What do you think it's worth, in real MOA?
I think it has to be less than .050. I mean, when it comes to real accuracy, .050 is a LOT. A whole lot. It's the difference between 1st place and about 100th place at a big bench rest match. My guess, for a rifle accurate enough to actually show the difference, it's not worth more than .025 MOA. In some circles, .025 MOA is still a whole heckuva lot.
But, let's say it's .050. Heck, let's go with it and say it's worth .075 MOA. Three quarters of a tenth, which is a chit ton, huge, if we're talking real accuracy.
My next question would be... How many rifles, can shoot well enough to really show .075 MOA? Less than a tenth. I know I do own several that absolutely can (they show no improvement from annealing though...). But those are high end customs. I have rarely seen a factory rifle that could show .075 as a consistent thing. My own guess, is less than 5% of the rifles owned by the members of this board could show that difference.
But I'm also guessing that is way more difference than annealing will actually provide! Because that is just such a big number. If it could really do that, there would be a lot of data around to support it and I'd have me an annealing machine for sure.
I'm even guessing that most well cared for and conscientiously loaded brass does not suffer from significant hardness and neck thickness variations. And anyone that would frequently anneal, would surely qualify as conscientious of their brass.
Add it up, and, well, I'm skeptical of all this annealing accuracy stuff. I really think it's me too marketing and wishful thinking. Before there were $500 machines to do it, nobody ever got too excited about it and there was plenty of experimentation and talk and such.
I could be wrong...
