ADIDAS69,
Good job on that.
I agree that the inherent accuracy concept is flawed. It's a matter of what appropriate components are available, especially bullet quality, what impression the quality of available commercial ammo gives, what the barrel twist rate choices are, and, of course, how well the handloader can do his job. Some cartridges have just been more thoroughly explored than others, giving the impression they must be better (assumed crowd wisdom). The old belief that the .30-06 and .222 Remington would always be inherently more accurate than .308 Winchester and .223 Remington was premised entirely on neck length difference. The assumption was better alignment could be got from a long neck. Well, there are match bullets with bearing surfaces shorter than the neck lengths in any of those cartridges, so they won't benefit from neck length. Plus, today we have better dies and measuring tools than were available when those rounds were developed and lots more powder and bullet and primer and brass choices. So, no, it doesn't really hold up.
BTW, please use the board's mandatory warning wording for hot loads. I put it in for you, but you can read about it in
this sticky at the top of the forum. Thanks.
