Jerry,
Thanks, very astute observations they are too. Tempering all this stuff with practicality, and sensability is the approach I take, but can afford to as well... no 1000yd BR up here ya know.
Some, if not most all my fiddling with the finer details like this are just a way to ensure upmost consistancy by catching the few (probably very few too) wild *** fliers from such causes, that's about it too.
How much groups open up from each one of these little details is unknown to me at this point, just know what I've read is all. Eliminating some of these things, well it allows me to focus on my load without much thought as to my component quality and consistancy causing fliers or high SD's.
I know BountyHunter is a strong advocate of bearing length batching, others batching of brass, others the Juenkee I.C.C. etc, etc. I just hope to quantify for myself at some point, what controling each one might gain me. If I can't measure its gain, it won't be worth nothin in the end but knowing it did or didn't. If all other variables are not elliminated, which is almost impossible with relaoding in and of itself, we can never put a number or a range of possible improvement on it. Part of me enjoys answering these questions for myself, part of me hates the livin hell out of doing it.
Kinda like verifying a drop chart for the umteenth million time with the same or, new load for what ever reason, when I'd like to be bounching around at unknown ranges testing my freakin skills on other things. Gotta keep the foundation solid tho, the other stuff don't mean squat if you don't keep the basis solid as a rock. Vertical IS something I can control, the other stuff I'm workin hard on gettin my hands around.
In the end, I'll be sacrificing a tenth or so MOA that others may never, like you said, comes down to wind mostly. Rangefinding ability and accuracy is right up there too. The RF deal can be dealt with if enough $$ is available, wind is purely upto an individuals ability and will always be a wild card in many ways.
