I'm wondering about the accuracy levels of plain base revolver bullets of single groove vs multiple grooves. I find lubing what looks like a Thompson style revolver bullet with multiple grooves harder to position correctly in a Star luber. The Keith styles are easy to hit with the larger, single groove and longer body style. I got to wondering if either style is more accurate than the other.
I have not seen any studies on it, nor have had anyone give anecdotal data.
