A few months ago, when i bought a comparator, i loaded up a batch of 20 rounds using a lee die in a lee press, using hornady bullets. I found that there was a difference of upto 8 thou between the longest and shortest. Since then, ive been checking every round loaded to ensure the OAL is correct. Nearly every time it needs tweaking to be spot on as i would say every other round would be out slightly.
Am i being OCD? Would more expensive dies give smaller discrepancies? Does it matter?
Well, actually, it matters to me, hence why im asking the question. It doesnt bother me for stalking but when playing around trying to optimise a load for the rifle, i want all variables the same apart from the one being tested..
The snag with checking each round is that it takes forever. I was thinking of getting some new dies anyways, ones with adjustable neck sizing bushes.
Next question.. has anyone had a go with a target master powder system? Ive gone off my digital scales (they were cheap) because they werent accurate to within +/- 0.5gn. So i have gone back to a balance beam, which is also Lee. Now although i think it is a little crude and may not be giving me exactly the charge i want, it is consistent. i think.
Im fully aware that the deer wont know the difference, or any other cliches along that line, but im looking at this from a more scientific PoV..
Mucho grassy ar*e!
