I got a LnL conversion for my rockchucker and have had nothing but problems so far. I spend more time trying to seat the damn die than if I just threaded the sucker in there. I get inconsistent resizes because I can't get the bushing to seat exactly at the same place every time. At this point I just took it off and will be threading them in. I wish they made the bushings have a grip surface with markings on them so you could lock them in exactly in the same place every time. Maybe I just got a defective one?
