Wes,
I would appreciate any references you could give me of tests that show that culling by weight improves accuracy. I have been wrong lots of time before.
I have never been able to find evidence that culling by weight improves accuracy, but about all my tests involve only one caliber and a limited range of bullets. Maybe for other situations it matters.
However, evidence such as a pair of ten shot groups or a few pairs of five shot groups mean absolutely nothing. As I mentioned, I already have the examples of a day's test of a few groups with culls vs. a few groups of uniform weight bullets that seem to show that the"good” bullets were more accurate.
The trouble is that I have an equal number of days when the same test shows that the culls shoot better.
If there are well controlled tests INVOLVING LOTS OF GROUPS that show that culling by weight improves accuracy, we should try to get the author to write it up for the Fouling Shot.
In other discussions of this topic some very good shooters have said that they don't know if it really helps but it gives them confidence and I think this is a legitimate reason.
I don't think anybody is advocating sloppy casting or loading but there are always weight and other variations in everything and the question is how much is too much.
