Some where I saw an accuracy test on as cast bullets and being out of round, They could get up to .005 -.006 with no real ill effects on accuracy .As long as it would chamber.

This was pistol I believe and I don't know the standard for how good of groupings were concidered acceptable. It would be a nice little test some day, but all my molds are MP, NOE, and Accurate so .001-.0015 is about the worst out of round I could test.

If you think about it, the bullets get swaged to the bore when shot, as long as the "average" diameter of the out-of-round bullet is a bit bigger than the bore diameter it should "size" round going down the barrel. Have no real proof, but would like to play with it.

Frankenmauser's bore rider wouldn't work out very well with that I wouldn't think.
