Has anybody done a comparison of straight versus not straight rounds in terms of accuracy? I'm somewhat serious with this question as I don't really know. All I ever did was replace the spent items to some degree and shot again.
FWIW I have. Not "extensively" but several hundred rounds.
I did the same thing wit' me' Juenke. More rounds than the straight VS crookedy test....
It is because of these tests that I now use fitted dies exclusively.
And haven't spun a bullet for 15yrs.......
