Im having trouble lube sizing these on my Magma Star sizer, I have the 90457 6 cavity mould. The lube Im using is the blue Magma lube. I don't have an air cylinder on the Star and my sizing die is .356. The issue is spots on the bullets lube groove not being filled with lube. I have the top punch at 33 1/2 mm from the casting which as I measured is in the middle of the grove when the handle is operated all the way down with the piston pushing lube and have tried some differ top punch depths , heat settings and have good pressure on the spring loaded lube reservoir . The lube groove on this 9mm bullet is very narrow and so I think its just a difficult one to lube because of that, sizing is not an issue they seat securely with a taper crimp. I also cast .38, 40 S&W , 44, 45 acp and 45 Colt bullets with out the troubles Im having with this 9mm. The grease grooves are well defined on my bullets no obstructions seen , as said just very small in size.
