Trying to size and lube some MP 454200 bullets. Using White Label Red 160 lube. I was successful with sizing/lubing a bunch of bullets from an NOE 452-230 mold, but I guess the bullet style is enough different that the MP bullets are giving me fits with getting the lube to inject into the groove (and STAY there) and ONLY in the groove. Too often the lube ends up in 3 small clumps on the nose of the bullet - lined up with the lube holes in the die. Then, the lube hole furthest away from the supply hole in the casting frequently leaves gaps in the lube groove. The gaps I can rectify by cranking up the pressure in the lube tube, but then the problems with lube getting on to the nose of the bullet increases. And all of this is affected by the temp of the lube as the Lyman (NOT Magma) heater grows warmer.
Whereas I managed to find the 'sweet spot' with the NOE bullets, these MP bullets are just NOT working out.
AAARRRRRGGGGGHHH
