Hello All

I need to know where I might be able to find a manual for the RL 450? I've been reloading for about 20 years or so and have never had a progressive press. Well some one has offered me a Square B and a RL 450 for a good price I think ($100), but I know nothing about them. I did download the manual for the Square B and for what I can tell it is all there, but I have no idea about the RL 450. Will the RL 550 manual be about the same? I have not contacted Dillon about it. Any help would be appreciated

Thanks in advance
Mike
