This may help with regards to case to moonclip reference. I've found too that Starline cases need the .025" clips but still are loose. I'm playing with Federal and R-P right now to find a more snug fit. Also check the ogive/profile of the Bayou vs Berrys too. You may find the Bayou is better for moon clip usage. Also FWIT I talked to Dave at Precision bullets in Texas and he makes me 125g RN coated, although they are not listed. I send him an order and when he makes his 9mm .355" swaged RN buyllet, he runs my .358" 125RN with them. Don't be in a hurry though, he only does it when he runs the 9's. Hope this helps..
