Thanks, @JonB . I read that back when I was struggling with my first RDO 359-190, like the one in @CWLONGSHOT 's recent post about a new paint color. I fought that mould for a while, and that article offered great insight. It did convince me that I wasn't going crazy, because I noticed a propensity for the several "micro-band" bullets I had exhibited this phenomenon - even the 22.
The article helped with all of them, but didn't cure the 359-190, as it was simply cut too small in the waist. It worked OK in a .355" groove ROssi 92 and is apparently working in the new recipient's Marlin, 35 Remington. The base and front band are big enough that the under-sized micro-bands seem to work like one great big grease groove.
I need to see if I can find so me pics of the gnarly bullets I've had this problem (per the OP) with.
