John and I have discussed this many times and while he considers rounded edges, frosty bullets and/or other small defects as not detrimental to accuracy [as in "Most of the advice you read about rejecting cast bullets for rifles is untested B.S."] he has been provided with ample "evidence" that rejecting such bullets and proper weight sorting is essential to best accuracy/precision.

Larry,
Sorry to be a little slow in answering, but I can't let your post stand without a bit of a rebuttal. The subject of the thread was about frosted bullets with slightly rounded edges producing some good groups for a factory rifle. I noted that such bullets usually shoot well since they have always shot well for me when I compared them to shiny bullets with sharp edges.
You seem to take offense to my claim. My memory isn't what it used to be, but I can't remember when you have ever provide me with evidence, ample or otherwise, on the subject of either frosted or rounded edged bullets. In fact I don't think we have ever discussed those two "defects." If this is just my faulty memory please give me a hint where I can find such evidence posted by you in the archives. Since I don't want to be saying things that aren't true, can you remember the threads involved or at least the category or perhaps repost your evidence.
As far as your implying that the limited quality of my equipment and/or limited shooting ability may be the reason for my questionable statement, you are absolutely right. Because I only shoot cast bullets in factory rifles, most of my testing as well as my competitive shooting is at the precision level of about one minute of angle for AVERAGES of five shot groups, seldom much better. So you are right, for shooters with custom built guns shooting AGGREGATES of much less than one minute these small defects may make a difference. I usually note that limitation in my articles but didn't in my post above.
However, for the 95% of cast bullet shooters whose average for strings of five shot groups is usually larger than one minute, the conclusions from my experiments should apply. If a defect can't be shown to affect groups averaging one inch it is unlikely that they will affect the two or three inch groups that most of us shoot.
